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?
