Kryptheon
Your AI says done. Kryptheon checks if your app still works
Your AI assistant says "done" without ever opening your app. Kryptheon checks. Record a flow once (sign up, log in, pay). After every AI change it replays it in a real browser and says in plain words what broke. It also attacks a copy of your Supabase or Postgres database's structure to find data anyone can read or change, without reading a real row. Works with Claude Code, Codex, Cursor, Antigravity and VS Code through MCP. Runs on your own machine.
Hi Product Hunt 👋 I'm the maker of Kryptheon.
I build with AI assistants every day, and kept hitting the same thing: the assistant says "done", but it never opened the app. Sign-up was broken, or a table it touched was readable by anyone.
So Kryptheon does two things:
1. You record a flow once. After each AI change it replays it in a real browser and tells you, in plain English, what broke.
2. It copies the structure of your Supabase/Postgres database (never the rows), attacks the copy as two made-up users, and shows what one customer could read or change of another's.
Add the MCP server (claude mcp add kryptheon -- npx -y kryptheon-mcp) and your assistant can run the check itself before it says done.
What it is not: nothing found is never called "safe". Every report ends with what could not be tested, and it does not replace a full security review. Apps on Lovable Cloud can't be scanned yet.
Starter needs no card. Pro adds the nightly details, the fix for each finding and an email every morning.
I would like to know whether you feel more confident about your project after using Kryptheon?
