Score: 6.8/10 (Innovation: 5, Technical: 7, Documentation: 8, Utility: 7)

Cognitox is an open-source local emulator for Amazon Cognito User Pools, enabling developers to test authentication flows without AWS dependencies. It's interesting because it implements 119 API operations in Rust with a hosted UI and admin console, filling a significant gap in local development tooling for serverless authentication.

Target audience: backend devs, devops, full-stack devs
