What is Buf?
Buf is a developer toolchain for working with Protobuf, gRPC, and ConnectRPC. It combines the Buf CLI for local schema development with the Buf Schema Registry, a hosted service that generates SDKs, produces API documentation, manages Protobuf plugins, and enforces policy checks so API changes do not break downstream consumers. It suits backend, frontend, and platform teams that maintain APIs across languages. The registry is sold through paid plans, while the CLI and related open source projects like ConnectRPC and Protovalidate are available for local use.
