Buf ORG

The best way of working with Protocol Buffers.

Buf is a CLI tool for Protocol Buffers that lints API definitions, detects breaking changes, generates code, and formats .proto files in one fast tool.

Build, format, lint, and check for breaking changes in your Protobuf schemas, and automatically publish to the Buf Schema Registry.
