Connect your GitHub and pick any repo. Heimdall handles the rest.
Sign in with GitHub and pick the repo you built. No installs, no config files, no terminal. The whole setup takes about ten seconds.
Heimdall runs every check in parallel: exposed API keys, broken auth, missing privacy policy, CORS holes, and a dozen more. You watch each one finish in real time.

CriticalYou move fast with Cursor, Lovable, Bolt, and v0. Heimdall makes sure nothing dangerous ships with your next deploy.
AI tools ship code fast, but they don't audit their own work. Heimdall checks for the gaps, misconfigs, and missing protections that slip through.
Every finding includes a fix prompt written for Cursor, Lovable, or Bolt. Paste, ship, move on.
Add an ownership check to DELETE /api/orders/[id]so the route compares the order's owner with the session user before deleting.
Exposed keys, missing auth checks, broken access control. The kind of stuff that blows up after launch. Caught before you push.
Essential protection for side projects before they go live.
Advanced hardening for shipping real products.
Total 360° integrity. No limits, no compromises.
