Buf is a modern CLI toolchain for Protocol Buffers that replaces protoc with a fast compiler plus linting, formatting, breaking-change detection, code generation, and dependency management. It also connects to the Buf Schema Registry for publishing, versioning, and governing Protobuf APIs.

Use cases

• replace protoc with a modern protobuf compiler
• lint protobuf schema files
• detect breaking changes in proto APIs before merge
• generate code from protobuf definitions
• manage protobuf dependencies across repositories
• format .proto files
• call gRPC APIs from the command line
• publish and version protobuf schemas in a registry

When to choose

• you work with Protobuf or gRPC and want to move beyond protoc shell scripts
• you need CI checks for API compatibility and style
• you want reproducible, declarative code generation via buf.gen.yaml
• you need a schema registry with generated SDKs and governance

When to avoid

• your project does not use Protocol Buffers or gRPC
• you need a GUI-based API tool rather than a CLI
• you only need a one-off proto compile and already have protoc set up
