Error tracking for your live v1 (UK SaaS, Claude Code 2026)
Your v1 is live, three founding members are using it, and the next outage is a question of when, not if. This is the right-sized observability layer for a brand-new UK SaaS: the three things actually worth watching, how to wire error tracking and a money-path alarm into a Next.js app with Claude Code in one session, source maps so a stack trace points at real code, a simple uptime ping, and the discipline to stop there instead of building enterprise monitoring for three customers.

Your first feature build session after launch (UK SaaS, Claude Code 2026)
Your v1 is live and three founding members are using it. The feedback is rolling in faster than you can build. This is the UK indie hacker guide to your first feature build session after launch: how to read founding feedback for the one signal that matters, pick the single feature that removes the most friction, scope it to one Claude Code session, build and test it against the money path, and ship it the same day with a 'you asked for this' note that turns a paying founder into an evangelist.

Ship your v1 to founding members (UK SaaS, Claude Code 2026)
Scaffold done, auth and billing wired. Now you ship the v1 to the founding members who already paid. This is the UK indie hacker go-live checklist: the pre-launch checks that stop launch day going sideways, how to onboard three pre-paid founders by hand, the feedback loop that tells you what to build next, and the first iteration cadence that turns a founding cohort into retained, paying customers instead of three refunds.

Supabase auth + Stripe billing for a UK SaaS (Claude Code, 2026)
Your skeleton is live. Now your founding members need two things: a way to log in and a way to keep paying you. This is the UK indie hacker walkthrough for wiring Supabase auth and Stripe subscriptions with Claude Code - the auth flow, the subscription model, the one webhook that actually matters, and the UK-specific decision every US tutorial skips: do you take payments through Stripe directly and own your VAT, or go through a Merchant of Record like Paddle and hand the VAT headache away?
Scaffold your validated v1 with Claude Code (UK, 2026)
You did the hard part. You ran the smoke test, made the Mom Test calls, and three founding members have already paid. Now you have to build the thing. This is the UK indie hacker walkthrough for turning a validated idea into a working app skeleton in a single Claude Code session: the PRD that anchors every decision, the CLAUDE.md that keeps the agent honest, plan mode before any code, the first five files, and why you deploy to Vercel on day one before you have a single feature.
Founding-member onboarding after the pre-sale - the UK SaaS playbook (2026)
Three Stripe receipts hit the inbox. Now what? Most UK indie hackers blow the handover - either over-promising delivery dates or going dark for six weeks while they build. Founding members convert at around 70 per cent to paid renewal when handled well; cold leads do not. This is the concierge onboarding kit: the 24-hour reply, the 15-minute kick-off call, the weekly Friday Loom cadence, the private channel, and the launch-flip that turns three pre-sales into three evangelists and the foundation of months 3 to 12 cashflow.
Mom Test customer interview questions for UK indie hackers (2026)
Most founder interviews fail because they reward the founder for asking and the customer for being polite. The Mom Test is a discipline for asking customer questions that produce signal, not soft praise. This is the UK indie hacker version: the ten questions that work, the GBP price-anchor question that earns its keep, the specific places to find UK candidates, and the three signals you must hear before you launch a Stripe pre-sale link.
Smoke-test landing page for UK SaaS with Claude Code (2026)
Before the pre-sale, before the Mom Test calls, before the build - there is the landing page. Not a marketing page for a product you already have, a smoke test for a product you have not built. This is the UK indie hacker walkthrough: the five sections that actually validate, the Claude Code prompt that drafts the whole page in one session, the Tally form that captures intent in pounds, and the 100-50-3 rule that tells you whether to keep going or kill the idea.
Pre-sell your UK SaaS with Stripe payment links before you build (2026)
A waitlist tells you people are curious. A pre-sale tells you they will pay - and it is the only validation signal that survives contact with reality. This is the founding-member pre-sale mechanic for UK builders: a Stripe payment link you can stand up in twenty minutes with Claude Code, the GBP pricing that converts, the honest refund promise that removes the risk, and the three-sale rule that decides whether you build. No product required - just a link and a price.
Build a competitor-teardown agent with Claude Code (UK, 2026)
Validation has a third leg after demand and willingness-to-pay: the competitive picture. This is a small Claude Code agent that scrapes competitor pricing and positioning pages with Firecrawl, extracts structured facts with Claude, diffs them week over week, and alerts you when a rival drops a free tier or hikes a price. Subagent architecture, the ethics, the validation step, and a GBP cost line that undercuts a GBP 100+/mo SaaS.
Read keyword data like a builder: free UK tools to size demand (2026)
Most keyword-tool roundups are written for marketers chasing rankings. This one is for builders deciding whether to write code at all. Search demand is the cheapest, fastest demand signal there is - free, readable in an hour, before you commit a weekend. Here is the free UK stack, how to read volume and intent like a build/no-build decision, the winnable-battle heuristic, and a small Claude Code script that aggregates it all into one CSV.
Validate a UK SaaS idea in a weekend with Claude Code (2026)
Validation is not the opposite of building - it is the cheapest build you will do all month. This is the weekend sequence: mine real complaints, ship a smoke-test landing page in the prospect's own words with Claude Code, drive a little paid traffic, run Mom Test calls, and ask for money. The harness itself is a one-evening Claude Code build. Decision rule, GBP cost line, and the one signal that actually counts.
Build a Claude Code morning brief agent (UK indie hacker, 2026)
A full Claude Code morning brief agent built in a single session. Pulls Companies House new directorships against your watchlist, GSC trailing 7d, and Met Office DataPoint, drafts the brief in Sonnet, sends via Resend at 6:55 every weekday. Deployable code, GBP cost line, smoke check, full pattern end-to-end.
Pool A vs Pool B: a UK indie hacker migration audit (June 2026)
On 15 June 2026 Anthropic splits Claude subscriptions into two pools. Interactive Claude Code keeps drawing from your normal plan; the Agent SDK and `claude -p` move to a metered Pool B. Here is the UK indie hacker audit checklist - which calls land where, what the GBP-per-month maths look like, and the decision tree for staying subscription, moving to API, or running dual pools.
Claude Code on Fly.io: a UK indie hacker global-edge worker (2026)
Fly.io gives you a micro-VM in the UK for the price of a coffee a month and scales to zero when idle. Here is how to deploy a headless Claude Code worker pinned to LHR, with GBP costs, scale-to-zero economics, and the Pool B billing notes that matter from 15 June 2026.
Claude Code on a Raspberry Pi at home: the GBP 50 always-on agent (UK indie hacker, 2026)
The Hetzner VPS is GBP 3.30/mo recurring. A Raspberry Pi 5 (8GB) is roughly GBP 80 one-off and zero recurring beyond the electricity. For a UK indie hacker who wants a Claude Code agent at home, the maths is interesting - here is the full setup, the ARM64 OAuth gotcha, and when the Pi beats the cloud box.
Claude Code observability step 2: alerting rules (UK indie hacker, 2026)
Yesterday's post got Claude Code metrics into Grafana. Today is what you do with them - Prometheus Alertmanager rules for daily cost thresholds, Pool B drain alerts, failed-job alarms, and runaway-loop detection. UK indie hacker setup, GBP costs, four alerts you actually need.
Vercel WDK + Claude Code: durable workflows for UK indie hackers (2026)
Vercel's open-source Workflow Development Kit turns ordinary async functions into durable, crash-safe workflows. Here is how to use it as an orchestration layer for Claude Code agents - and when it beats systemd timers or Anthropic Routines for a UK indie hacker.
Claude Code observability on a budget: OpenTelemetry to self-hosted SigNoz for GBP 0 (UK 2026)
Pool B spend visibility is the whole game from 15 June 2026. Claude Code already emits OpenTelemetry metrics and traces. Wire them to a self-hosted SigNoz on a Hetzner VPS and get a single dashboard for every agent, every token, every tool call, for GBP 0 in software.
Claude Code on a Hetzner / UK VPS: the 2026 UK indie hacker setup
A VPS gives your Claude Code agents the one thing a laptop cannot: persistence through laptop close. Here is the GBP 3.30 a month setup on a Hetzner ARM box, the Cloudflare OAuth workaround that catches everyone, and the UK provider price comparison.
Claude Code on Linux: cron vs Routines vs systemd timers (UK indie hacker decision matrix, 2026)
Three ways to schedule headless Claude Code on Linux in 2026: classic POSIX cron, Anthropic Routines, and systemd timers. Here is the decision matrix, the GBP cost of each, and the sensible default for a UK indie hacker.
The 15 June 2026 Claude credit split: what UK indie hackers should do this month
Anthropic announced on 13 May 2026 that from 15 June, programmatic Claude usage moves to a separate monthly credit pool, capped at subscription price. Here is what the numbers actually mean for a UK indie hacker, and the four things to do in the four weeks of runway.
Deploy a headless Claude Code worker to Railway: a UK indie hacker guide for 2026
When the home PC is the wrong host - webhooks, public endpoints, multi-user triggers - Railway is the cleanest move for a UK indie hacker. Sterling billing, EU regions, a Dockerfile-or-Procfile worker. Here is the full walkthrough, including the storage and env gotchas.
Claude Code on Windows Task Scheduler for UK indie hackers in 2026
Your UK desk PC is on anyway. It is cheaper, faster, and more private than a cloud worker for most overnight jobs. Here is how to wire Claude Code into Windows Task Scheduler properly: PATH, working directory, NonInteractive, logging, and a 7am morning brief that just works.
Multi-agent Claude Code orchestration patterns for UK indie hackers (2026)
One agent is enough until it is not. The moment your build has a planning step, a building step, and a review step, you want orchestration. Here is the UK indie hacker playbook for multi-agent Claude Code: the five patterns that earn their keep, the ones that do not, and a weekend morning-brief worker pool you can ship.
Headless Claude Code: claude -p scripting for UK indie hackers (2026)
Most UK indie hackers run Claude Code as a chat. The -p flag turns it into a one-shot CLI you can drop into bash, cron, GitHub Actions, or a Vercel cron job. Here is the headless playbook: piping, JSON output, allowed tools, max turns, and a 50-line weekend scraper.
Claude Agent SDK for UK indie hackers: build your own programmatic AI coder in 2026
Claude Code is brilliant when you sit in front of it. But what if you want an agent that runs without you? The Claude Agent SDK is the same engine, exposed as a library. Here is how a UK indie hacker uses it to build their own schedulers, scrapers, and ops bots in a weekend.
Claude Code in GitHub Actions for UK indie hackers: the auto-fix CI workflow that fixes failing tests while you sleep
Push a branch at 17:00, CI goes red, you are on a train, the fix waits until 19:30. Claude Code in GitHub Actions removes that: when a build fails, the agent reads the logs, traces the root cause, writes a fix, and opens a PR before you see the notification. A complete auto-fix workflow file, cost controls in GBP, and the security guardrails an autonomous CI agent needs.
Claude Code memory and context management for UK indie hackers: how to keep a long build cheap and on-track
Every UK indie hacker hits the same wall around hour two of a long Claude Code session: the agent starts forgetting things. That is a context window filling up. Two memory systems, the /compact mechanics, the 80% rule, and the task-chunking maths - an atomic task needs 5-10k tokens, a do-everything session needs 80k - that is the biggest lever on a solo founder's token bill.
Claude Code slash commands and skills for UK indie hackers: the six custom commands that turn the agent into your team
Most UK indie hackers use Claude Code like a fast junior dev, typing the same instructions every session. Custom slash commands and skills fix that: a markdown file in .claude/commands becomes a /command, a skill the agent can also reach for on its own. The six copy-paste commands a UK micro-SaaS founder actually uses, and the one rule that decides which jobs become commands and which become skills.
Claude Code plan mode for UK indie hackers: the three-screen ritual that stops the one-shot disaster
The fastest way to brick a weekend project is to one-shot a refactor. Plan mode is Shift+Tab+Tab and a fundamentally different agent posture - the agent looks, drafts a plan, and only edits once you've agreed. The three-screen ritual that stops the one-shot disaster on Stripe Checkout, live Supabase migrations, and billing webhook rewrites.
Claude Code MCP servers for UK micro-SaaS: the four wires (Stripe UK, Supabase EU, Postgres, GitHub) and one rule that stops the agent guessing
Every Claude Code user hits a wall around month two: the agent can edit files but cannot see your Stripe charges, your Supabase rows, or your GitHub PRs. So it guesses. MCP fixes that. This is the UK micro-SaaS primer for the four servers that move the needle - Stripe UK, Supabase EU, Postgres, GitHub - plus the one read-only rule that keeps the agent safe.
Claude Code hooks for UK indie hackers: the eight automation patterns that pay for themselves on the first ship
The vibe-coder crowd treat Claude Code hooks like dev-ops ceremony. They are not. Hooks are the cheapest insurance a UK indie hacker can buy: a few lines of shell in settings.json that catch the rogue rm -rf, the force-push to main at 23:30, the leaked Stripe key in a debug log. Eight patterns that pay back inside the first weekend.
Claude Code subagents for UK indie hackers: the parallel-build unlock
Most UK indie hackers using Claude Code never touch subagents. They are the single biggest unlock in the tool, and they are buried two levels deep in the docs. The result: weekends that should ship five things ship three. This post fixes that - the 30-second definition, three concrete weekend scenarios where subagents save 60-90 minutes each, copy-paste prompts for each, and the honest 'when not to use them' because they are a power tool, not magic.
CLAUDE.md for UK indie hackers: the project file that compounds week over week
Every UK indie hacker who tries Claude Code reaches for CLAUDE.md within a week. The Anthropic docs tell you it exists; generic dev blogs tell you it is where project rules live. Neither explains the thing that actually matters: CLAUDE.md is the file that turns Claude Code from helpful assistant into a builder that compounds. The 7 sections that earn their keep, the 3 anti-patterns that look helpful but rot the file, and a real copy-paste 80-line template.
Cursor vs Claude Code vs OpenCode: the UK indie hacker three-way for 2026
Yesterday we did the visual-builder three-way (Lovable vs Bolt vs Replit). Today is the IDE/agent layer underneath: Cursor, Claude Code, and OpenCode. The top of the SERP is US-shaped - global comparison sites, USD pricing, no UK angle. This post is the UK-builder primer. GBP throughout, a three-question decision tree, and the two-tool combo most weekend builders settle on by month two.
The weekend vibe-coding playbook: ship a paid UK micro SaaS Friday to Sunday
Vibe coding started as Karpathy's weekend habit. Two years later it is how a measurable share of UK indie hackers ship their first paid product. The SERP is full of definitional think pieces; what is missing is the hourly weekend plan that actually gets a real GBP-5/month UK micro SaaS live by Sunday night. This is that plan - Friday 18:00 to Sunday 22:00, exact AI stack at each checkpoint, the five things to cut, and a Monday recovery plan if you slip.
Lovable vs Bolt vs Replit: the UK builder's head-to-head for 2026
Three AI app builders take the bulk of indie-hacker mindshare in 2026 - Lovable, Bolt, and Replit. Every comparison out there is written either by one of the vendors or by a US-centric content site. This is the UK builder's version: independent, priced in GBP, with UK Stripe and Supabase EU wiring notes, and a five-job decision matrix that tells you which builder wins for each common UK side-hustle shape.
Claude Code first project for UK indie hackers: install to deploy in 30 minutes
Two ways UK indie hackers are using AI in 2026: as an in-IDE copilot, or as the IDE itself. Claude Code is the second shape - the agent that runs in your terminal, reads the project, edits files, runs tests, commits. This is the missing UK-native, GBP-priced, install-to-paid-product walkthrough: install Claude Code, scaffold a Next.js 16 + Supabase EU + Stripe UK GBP micro SaaS, deploy to Vercel, and have a first paying customer flow in 30 minutes of clock time.
IP assignment from your sole-trader period to your new Ltd: the silent SEIS-killer for UK indie hackers (2026)
You built the MVP as a sole trader. You have 50 paying customers. You incorporate, raise GBP 75k SEIS, and four weeks later HMRC writes back: SEIS refused, the company does not own the asset it is raising on. The IP is still legally yours - the sole trader. The fix is a one-page IP assignment deed, executed before the SEIS Advance Assurance application is filed. This walks the timing, the deed template, and the three SEIS-killer mistakes UK indie hackers make on the sole-trader-to-Ltd transition.
Founder vesting and reverse vesting at pre-seed: the UK SaaS playbook with worked SAFE follow-on maths (2026)
Standard advice says 4-year vest with a 1-year cliff, good leaver / bad leaver, done. The reality for a UK indie SaaS pre-seed is messier - you do not need vesting before the first cheque, reverse-vesting is the structure that keeps founder shares on CGT not income tax, and the SAFE / convertible note follow-on round can quietly reset the vesting clock if you are not careful. This walks the timing question, the tax distinction, and a worked GBP example through a GBP 75k SAFE round at a GBP 3m valuation cap.
AMV vs UMV: the HMRC EMI valuation maths walkthrough for a UK SaaS founder (April 2026 expansion edition)
AMV (Actual Market Value) and UMV (Unrestricted Market Value) are the two share prices HMRC wants on every EMI grant - and getting the gap between them right is what turns a GBP 20k EMI grant into a defensible 35-point tax swing for your first hire. This walks the April 2026 expansion (GBP 120m gross-asset cap, 500-headcount cap, GBP 6m total-pool cap), the minority-discount / restriction-discount stack, and worked GBP arithmetic at a GBP 750k pre-money valuation so you can see both sides of the maths.
PSC register first run for the UK indie hacker: alphabet shares, nominee shareholders, and the 25 percent UBO trap in 2026
Year one of a UK Ltd: PSC register has one entry, you. Year two: co-founder via alphabet shares, SEIS angel via a nominee, spouse on B-shares for inheritance planning. Suddenly the PSC register has four candidate entries, two of them are not registrable for the reasons you would expect, and getting it wrong is a criminal offence. This walks the five PSC tests, the Nov 2025 Companies House register move, the 2026 mandatory ID verification, and three worked alphabet-share cap tables for the year-two indie SaaS.
EMI share options for your first hire: the April 2026 expansion, the 92-day HMRC clock, and the worked arithmetic for a UK SaaS founder
Your first hire is the most consequential decision a UK indie SaaS founder makes. EMI share options turn a GBP 60k cash-only hire into a GBP 35k cash-plus-options hire who is more committed than the cash-only version. April 2026 expanded the regime: doubled headcount cap to 500, quadrupled gross assets to GBP 120m. This walks the 25-hour working time test, the 92-day HMRC clock, the AMV vs UMV split, and worked GBP arithmetic on a 15k base + 20k EMI grant at a 750k pre-money valuation.
SEIS Advance Assurance for the UK side-hustle SaaS founder: the GBP 250k cap, the 6-week HMRC clock, and the worked arithmetic on a 75k seed in 2026
The UK indie hacker who is still on PAYE somewhere and shipping a SaaS on the side has one extraordinary advantage: SEIS. 50% income tax relief on a GBP 25k angel cheque means it costs the angel GBP 12,500 net of tax. This walks the GBP 250k SEIS cap, the GBP 5m EIS top-up, the Advance Assurance pack, the 8-week-before-round rule, and worked GBP arithmetic on a 75k seed at 750k pre-money so you can see the cap-table maths from both sides.
Stripe vs PayPal vs GoCardless for the UK indie hacker (2026 fee comparison + decision tree)
Stripe charges 1.5% + 20p on UK cards, GoCardless caps Direct Debit fees at GBP 4, and PayPal sits at 2.9% + 30p with a brand-trust premium. None of the global comparison posts work the actual GBP arithmetic for a UK indie hacker shipping in 2026. This is the comparison that does: real fee math on a GBP 14.99 transaction, churn implications for recurring billing, chargeback exposure in plain English, and a four-question decision tree that gets you to the right processor in under a minute.
Reddit and X distribution for UK indie hackers in 2026: the subreddit map and non-engagement-loop fix
Reddit and X are the cheapest distribution UK indie hackers can run, and the most commonly fumbled. Reddit is intent-rich and the UK has a strong subreddit ecosystem; X is broadcast-cheap and the LA-morning slot lets a UK builder reach US makers without staying up. This post is the UK-native combo playbook: the UK subreddit map with per-sub self-promotion rules, the X non-engagement-loop fix, the Reddit-to-X flywheel, and a 14-day starter calendar.
First 100 organic visitors as a UK indie hacker in 2026: the SEO flywheel playbook
100 organic visitors a month is where channel-message fit becomes legible. At a 2 percent conversion rate, that is two paying customers at GBP 14.99, GBP 30 MRR, and the first feedback loop closes. This post is the UK-native SEO playbook for indie hackers in 2026: the free stack (GSC, GA4, Plausible), keyword research with Claude Code, the UK long-tail multiplier, three UK content patterns that index fast, linkable UK assets, and a realistic 90-day timeline.
Product Hunt launch from a UK timezone in 2026: the indie hacker timezone-calculus playbook
Product Hunt launches start at 12:01am PT - 8:01am UK in winter, 9:01am UK in summer. UK indie hackers need a 16-hour conscious window to ride the launch through to the LA evening surge, and the most common UK failure mode is going to bed at 11pm UK and missing the peak voting hour. This post is the UK-native Product Hunt playbook: timezone calculus, two scheduling options, the UK pre-launch list, hour-by-hour launch day, and the 5 mistakes that kill non-US-maker launches.
Stripe Atlas UK alternative for indie hackers in 2026: sole trader vs Ltd in 4 hours, with a decision tree by revenue
Stripe Atlas is the Delaware C-corp incorporation route US indie hackers default to. For a UK-resident indie hacker trading in the UK it adds US tax filings, foreign-resident complexity, and zero practical benefit. This post is the UK-native alternative: sole trader in 10 minutes via HMRC for free (suits GBP 0 - 40k revenue), or Ltd via Companies House in 4 hours for GBP 50 (suits GBP 50k+ or contracting). Decision tree by revenue, full Saturday morning checklist, and the Stripe + bank + accounting stack that fits each.
AI side hustle from GBP 0 to GBP 1k MRR in the UK in 2026: a month-by-month playbook for the 9-to-5 indie hacker
GBP 1,000 MRR is the threshold where a side hustle starts to behave like a business. Get there as a UK indie hacker on a 9-to-5 and the calculus of leaving the day job changes. This is the month-by-month playbook from GBP 0 to GBP 1k MRR using Claude Code, Vercel, and Stripe - 8-12 weekend hours a week, the MRR/users/cost table at each stage, the UK tax checkpoints that bite at the GBP 12,570 personal allowance and GBP 50,270 higher rate, and what breaks at month 4.
Indie hacker first paying customer in the UK in 2026: the GBP 14.99 user playbook from build to bank account
The first paying customer is the only signal that means anything before you have a product. Most playbooks are written by US founders who incorporated in Delaware and reached a global audience on launch day. UK indie hackers operate differently - sole trader instead of Ltd in month one, GBP pricing instead of USD, and a domestic audience that does not hang out on Hacker News. This post is the UK-native playbook: why GBP 14.99 is the right anchor, the 5-step path from build to first sale using Claude Code and Vercel, the UK distribution channel matrix, and the traps that kill the first sale.
Base44 review 2026: the honest UK indie hacker take on the all-in-one builder and the platform lock-in trap
Base44 launched late 2024, hit 2 million users by end of 2025, USD 100 million ARR by early 2026, and was acquired by Wix for USD 80 million cash. The speed is real; a working CRM in under 10 minutes is a real benchmark. The catch is one sentence long and matters more than any of the tier comparisons: you cannot export the backend. This is the UK indie hacker honest take - what Base44 is brilliant at, the platform lock-in trap named upfront, and when it is and isn't the right call.
Replit Agent for UK indie hackers in 2026: the 45-minute SaaS test, where it falls apart, and the GBP cost of taking it seriously
Replit Agent 3 really did ship a SaaS billing dashboard with Stripe, auth, and usage analytics in 45 minutes - that benchmark is real. The harder question for UK indie hackers: is the code something you can maintain in six months? This post takes the honest builder view: what the 45-minute test actually delivers, where Agent 3 falls apart, the GBP cost of going Pro, and the ship-to-validate-then-refactor pattern that keeps the speed without the long-term tax.
Lovable vs Bolt 2026: the UK indie hacker buyer's guide with GBP pricing, three founder profiles, and a one-week test plan
USD pricing pages do not help when you are paying with a UK Mastercard. Here is what each costs in GBP, three UK indie hacker founder profiles to map yourself to, and a one-week test plan that gives you a sharp answer for under GBP 40 - so the choice is about what you are building, not what is cheapest.
Ship a UK SaaS in a weekend with Claude Code + Vercel + Supabase: the Friday-to-Sunday playbook with GBP costs and the four mistakes that kill the timebox
Two days. One UK SaaS. The Claude Code + Vercel + Supabase + Stripe stack from Friday-evening init to Sunday-night production smoke test. Under GBP 30/month, the four mistakes that burn the timebox, and what to ship Monday morning.
Cursor vs Claude Code in 2026: the UK indie hacker buyer's guide with GBP pricing, three founder profiles, and a one-week test plan
Cursor or Claude Code? GBP pricing for both, three founder profiles (greenfield MVP, mid-codebase iteration, production refactor), the 30-minute switching cost reality, and a one-week test plan that gives you a sharp answer for under GBP 32.
Claude Code first-week starter playbook for UK indie hackers: the four commands you actually use, your first feature, and the mistakes that burn a week
Day one to day seven with Claude Code: install, four commands, a hand-written CLAUDE.md, the first feature you should actually build, the four mistakes that burn a week, and the GBP 17/month UK indie hacker budget.
UK SaaS VAT place of supply 2026: B2C EU sales, B2B reverse charge, OSS Non-Union registration, and the US sales-tax trap
You are a UK-based SaaS founder, your first paying customer is in Berlin, your second in San Francisco. Stripe charges them whatever you tell it to. VAT? Place of supply rules say two different things depending on B2B vs B2C - and post-Brexit the UK is a non-Union supplier of digital services. Get it wrong and HMRC will not refund you. This is the 2026 decision matrix.
UK SaaS bookkeeping stack 2026/27: FreeAgent vs Xero vs Pandle for solo founders, MTD ITSA readiness, and when to switch
MTD ITSA went live 6 April 2026 for self-employed earning over GBP 50k. The bookkeeping software question is no longer optional. A solo SaaS founder needs three things: MTD-compliant submission, multi-currency Stripe-friendly receipts, and bank feed reliability. Three serious contenders - FreeAgent, Xero, Pandle - different price points, different sweet spots. This is the founder-first decision matrix.
UK SaaS micro-entity accounts 2026/27: the £1m turnover threshold, FRS 105 vs FRS 102 Section 1A, and what to actually file at Companies House
Your accountant probably files full small-company accounts (FRS 102 Section 1A) by default. From April 2026, more UK SaaS founders qualify for FRS 105 micro-entity accounts after the £1m turnover threshold raised. The micro-entity route is shorter, cheaper, exposes far less detail to competitors, and saves £400-£900 a year on accountancy fees. Most solo SaaS founders should be filing FRS 105.
UK SaaS sole trader to Limited company switch 2026/27: the GBP 50,270 trigger, incorporation relief s.162, and the clean transition timeline
The single best switch trigger for a UK SaaS sole trader is the GBP 50,270 higher-rate threshold. Below that, sole trader simplicity usually wins. Above that, Limited company saves significant tax via dividend optimisation, employer pension contributions, and corporation tax efficiency. Worked example: GBP 60k profit, sole trader keeps GBP 41k. Limited keeps GBP 47k. That GBP 6k uplift compounds with the SIPP route to GBP 30k+ a year. Plus incorporation relief s.162 shields the goodwill.
UK SaaS founder pension SIPP solo director 2026/27: the employer route, the GBP 60k allowance, and how the company pays the SIPP for a 33-38k tax saving
The employer pension contribution is the single most tax-efficient compensation move available to a UK SaaS solo director — and most founders miss it for years. Up to GBP 60,000 per year goes from company bank to your SIPP with zero NIC, zero income tax, and the company saves 19-25% corporation tax on the same money. Worked example: GBP 60k contribution saves GBP 33-38k in tax vs the dividend route on the same cash.
UK SaaS founder PAYE first salary registration HMRC 2026/27: the GBP 12,570 sweet spot, the GBP 6,240 LEL anchor, and the solo-director walkthrough
First salary as a solo director is the most-asked question in UK SaaS founder Slacks. The answer is anchored on two numbers: GBP 12,570 (the practical sweet spot for tax efficiency) and GBP 6,240 (the LEL anchor that buys you a state pension qualifying year). This walkthrough covers the 2026/27 thresholds, why GBP 12,570 beats GBP 9,100, the HMRC PAYE registration mechanics, and the four mistakes solo founders make on first salary.
UK SaaS Companies House strike off 2026: voluntary DS01 vs HMRC striking off vs solvent winding up for a failed indie SaaS
Closing a UK Limited isn't failing -- it's freeing capital. The right route depends on what's left in the company and your tax position. DS01 saves GBP 2,000 in liquidator fees for failed indie SaaS; MVL with BADR saves five figures on bigger wind-downs. Here's the decision tree, with worked numbers.
UK SaaS S455 director's loan tax 2026/27: the 9-months-1-day window, beneficial loan threshold, and the GBP 8,000 calendar trap
Most UK SaaS founders take a director's loan at some point. The s455 tax is HMRC's enforcement mechanism: 35.75% on any unrepaid balance 9 months and 1 day after year-end. This guide walks through the precise window, the GBP 8,000 calendar trap, and the L2P refund route.

UK SaaS R&D tax credit 2026: the merged scheme, ERIS for loss-making indie SaaS, and how a solo founder can claim £20k-£50k back from HMRC
Most UK SaaS indie founders don't claim R&D tax credits because they assume R&D is what big companies with research labs do. Wrong. Under the merged scheme that applies to accounting periods from 1 April 2024, qualifying activities include solving genuine technical uncertainty in your dev work. Loss-making SMEs with R&D over 30% of expenditure get 27% cash back via ERIS. For a solo founder spending £80k-£120k on a technically novel product, that's £20k-£50k back from HMRC.
UK SaaS VAT registration 2026: voluntary vs the £90,000 threshold, the flat rate scheme decision matrix, and why most indie founders should wait
The 2026/27 UK VAT threshold is £90,000 in any rolling 12-month period. Below that, registration is voluntary. Most B2B SaaS founders should register from day 1 to capture input VAT reclaim. Most B2C founders should wait until forced. The Flat Rate Scheme's 'Computer and IT consultancy' 14.5% rate combines with the limited-cost-trader test to produce a 16.5% effective rate that wipes out the scheme's main benefit for most pure SaaS.
UK SaaS accounting reference date 2026: how to pick yours, when to change with Form AA01, and the calendar trap that costs solo founders thousands

This is the founder-side walkthrough: which ARD to pick, how to change cleanly with Form AA01 in year 1, and the £8,000 calendar trap that catches founders 21 months in.

UK SaaS error budget and SLO setup 2026: Vercel + Better Stack + Sentry, the 30-min ship-it
