Repairo is a CLI tool that automatically fixes breaking changes in your codebase caused by third-party API updates. It uses OpenAPI spec diffs to detect breaking changes, maps the impact using AST analysis, applies deterministic repairs, validates with typecheckers, and opens a reviewable PR. The project stands out by combining dependency bumping with actual call-site repair, grounded in formal API contracts rather than probabilistic AI guesses.

Target audience: backend developers, full-stack developers, devops, platform engineers
