ProtoPatch

Validate protobuf schema changes for backward and forward compatibility

Code & DevelopmentFree

ProtoPatch validates Protocol Buffer schema changes against backward and forward compatibility rules, catching breaking changes like field number reuse, type incompatibilities, required field additions, and enum value conflicts before they reach production. The tool maintains a schema evolution timeline and generates migration guides for consumers when breaking changes are intentional. API platform teams use it as a CI check to enforce their compatibility contracts.
