Find out your signup is broken
before your users do.

FlowSnitch clicks through your app's signup, login and checkout every day, scans for leaked API keys, and emails you the moment something breaks. Made for vibe-coded and small web apps.

Free, read-only, about 30 seconds. We only load public pages and never submit forms.

AI plans your checks once

Add your site and FlowSnitch maps your key journeys: sign up, log in, pricing, checkout. Then it replays them every day with no AI guesswork.

Catches what uptime monitors miss

Your homepage can return 200 while signup throws a 500. FlowSnitch fills the forms with test accounts and tells you exactly which step failed.

Security scan built in

Leaked Stripe or OpenAI keys in your bundle, a public .env, Supabase service keys, missing HTTPS headers. These are the mistakes AI-generated code makes most.

How it works

  1. Run a free Launch Check on any URL to get a grade and a fix list.
  2. Create an account and add your site. Prove you own it with a meta tag or DNS record.
  3. FlowSnitch plans your flow checks and runs them daily. Test signups use you+fstest-…@ addresses and send an x-flowsnitch-test: 1 header so you can filter them out.
  4. You get an email when something breaks, and another when it's fixed.
