Builds
Pick what you want to make. Each build lists the blocks, how they connect, the steps, what will catch you out and the monthly cost as you grow.
Web apps 3
Products people sign in to, use and pay for.
Auth-heavy B2B app (Neon + Clerk)
A B2B SaaS that keeps auth separate from the database, with organisations, MFA and no third-party branding.
Internal dashboard
Stand up an internal dashboard your team can log into — tables, filters, and a safe data path — without overbuilding or guessing the monthly £ bill.
SaaS with payments
Ship a small paid SaaS: sign-up, a simple product surface, and UK card billing — with a clear monthly £ bill at launch, ~100 users, and ~1,000 users.
AI 2
Apps and agent teams that run on AI models.
AI chatbot app over your own content
A deployed chat assistant that answers from your own docs, FAQ and product pages. It stores each user's history, runs moderation on input and has a spend cap on the AI API.
Cheap AI agent team (Sonnet/Opus lead + Haiku subagents)
Run a coding or ops agent team on the Claude API. A lead model plans and reviews, and cheap Haiku subagents do the routine work, for about 68% less than an all-Sonnet team.
Selling online 2
Taking money for downloads, courses and listings.
Digital products shop (downloads / courses): Stripe vs merchant of record
A storefront for a UK creator that takes payment and delivers the file or course access. VAT is handled either by you (Stripe) or by a merchant of record (Lemon Squeezy or Paddle).
Directory site with paid listings
A searchable, SEO-friendly niche directory where businesses pay by card to submit or feature a listing. It sends a confirmation email and puts each listing in an approval queue.
Mobile 1
Apps for iOS and Android.
Launch and security 2
Getting ready to go live, and staying safe once you do.
Pre-launch security pass for vibe-coded apps
Before you launch a vibe-coded Supabase + Vercel app: turn on RLS checks, secret/dependency scanning, hosting hygiene, and optional AI code review — with a clear £0–£22.47/mo add-on bill.
Waitlist / landing page
Launch a clean waitlist: landing page, signup capture, and confirmation email — on a £0 free-tier stack (or a small paid hosting upgrade if you need commercial Vercel).
