Utility for comparing two OpenAPI specifications.
This repository describes an ignore specification, and can be used to integrate with OpenAPI-diff and customize your breaking changes.
CI-friendly OpenAPI breaking-change detector for versioned API contracts, with local diffs and machine-readable results.
Fails your CI build when a third-party API you actually call changes in a way that can break you. GitHub Action + OpenAPI diff, filtered to the endpoints you declare.
Browser-based OpenAPI breaking-change detector: paste two specs, get a plain-English report of what breaks your clients.
Learn what your API actually returns from recorded traffic, then diff that observed contract against your OpenAPI spec (JSON or YAML) and report the drift.
Detect breaking changes in your OpenAPI spec on every PR. Powered by monit.rs.
