BreakShield CI
Catch breaking API changes in pull requests before they ship
BreakShield CI is a GitHub App that automatically detects breaking API changes in every pull request. It parses TypeScript interfaces and OpenAPI specs using a full AST — not regex — and finds exactly which files and lines will break. Results appear as a PR comment and Check Run within seconds. What makes it different: - AST-verified evidence with exact file:line locations - Confidence scoring filters out noise automatically - Blocks merge on HIGH/CRITICAL risk - Free during beta
Hey Product Hunt! 👋
I built BreakShield CI after spending too many hours debugging production issues caused by breaking API changes that slipped through code review.
It installs in 30 seconds and works on every PR automatically. Would love feedback from anyone working with TypeScript APIs or microservices.
