APIVersionDiff

Detect breaking changes between API versions from OpenAPI specs

Code & DevelopmentFreemium

APIVersionDiff compares OpenAPI specification versions to identify breaking changes including removed endpoints, changed parameter types, narrowed response schemas, and modified authentication requirements. The tool classifies changes as breaking, non-breaking additive, or non-breaking compatible, and generates migration guides for API consumers explaining how to update their integration for each breaking change. API platform teams use it to enforce semantic versioning contracts and produce accurate changelogs.
