BreakShield CI
Catch breaking API changes in pull requests before they ship
What is BreakShield CI?
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
