| What makes it different | - Catches bugs code review misses by running the actual product instead of just reading diffs
- Every bug comes with a reproducible failing test that proves it
- Finds runtime vulnerabilities by firing real exploits against the sandbox
- Tests untested integrations and hard-to-mock async services
- Free for open source projects
| - No setup, API key, or third-party trackers required
- Transparent methodology with published formulas and per-model rates anyone can verify
- Works across 10 major AI platforms with a single extension
