The problem
Vibe coders ship sloppy AI-pair-coded SaaS.
Claude Code is genuinely useful. It can scaffold a full stack in an afternoon, refactor a module without breaking the tests, and write the boilerplate you'd never write yourself. The problem isn't Claude. The problem is that most setups have no guardrails — no memory of past decisions, no protection against the named catastrophes, no honest accounting of what it can and can't do without supervision.
The result is a specific failure mode: a vibe coder who ships fast, ships confidently, and every few months loses two weeks to a disaster that was entirely predictable and entirely preventable. The service-role key that sat on the public site. The production table that vanished during a "small" migration. The force-push that erased two months of authentication work.
These aren't hypotheticals. They're a catalog — things I've personally seen, mostly from people too embarrassed to admit it publicly.
The solution
A senior-developer Claude Code setup in sixty seconds.
Claudekit installs a structured .claude/ configuration via a single MCP tool call: a CLAUDE.md with opinionated defaults, a set of catastrophe-blocking hooks, and a reviewer agent that watches Claude's work. Nothing is hidden from you — the manifest preview shows you exactly what will land before it does.
The personal area gives you a live view of what's actually installed in each project, which disasters your setup covers, and which ones it doesn't. We show the gaps on purpose. Hiding them would make the product easier to sell and harder to trust.
"The kit is what I'd build for my own projects if I had a weekend and no other obligations. Now it installs in sixty seconds."
The builder
Berlin-based. Seen too many disasters.
I'm Mitja Eichhorn. I've spent the last several years watching vibe coders and semi-technical founders use AI pair programmers to ship faster than they've ever shipped — and make the same class of catastrophic mistakes faster than they ever have. Claudekit is the setup I'd hand them before they hit the first disaster, not after.
