Why Heimdall?

Vibe coding moves fast. Heimdall acts as your silent guardian — catching every security gap and production risk before your users do.

Expose Hidden Secrets

Heimdall scans every file in your repository for hardcoded API keys, tokens, and credentials — before attackers find them first.

Shield Against Attacks

We check your CORS policy, security headers, and authentication flows so your app can't be hijacked or impersonated.

Ship with Confidence

From missing SEO tags to broken environment configs, Heimdall surfaces every issue that could embarrass you in production.

Ran this before my first real user signed up. Found a CORS misconfiguration I had no idea about.
