SchemaDiff

Detect breaking changes between API schema versions automatically

Code & DevelopmentFreemium

SchemaDiff compares OpenAPI, GraphQL, Protobuf, and Avro schema versions to identify breaking changes including removed fields, type narrowing, new required parameters, and enum value removals. The tool classifies changes as breaking, non-breaking, or potentially breaking with detailed impact analysis showing which clients would be affected. API platform teams run it in CI to gate breaking changes while API consumers use it to understand what changed between versions and assess migration effort before upgrading.
