Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

Arol is a CLI tool that scans local code repositories for usage of third-party APIs with upcoming deprecations, detecting deprecated calls at the source-code level rather than just package manifests. It operates fully locally without network calls, making it a practical CI gate for catching deprecated API usage before it breaks.

Target audience: backend devs

Repository: https://github.com/benminor/arol · TypeScript
