Buf CLIThe all-in-one Protobuf toolchain

‍Generate code, prevent breaking changes, lint Protobuf schemas, enforce best practices, and invoke APIs with the Buf CLI.

Try the CLI

Safely evolve your APIs across platforms

Ensure you never cause an outage by shipping a breaking, backward-incompatible change to production by using the Buf CLI to validate API changes both locally and in continuous integration (CI).

Generate code without managing a Protobuf environment

Generate code locally using the Buf CLI or remotely in an isolated environment on the BSR without worrying about managing compiler versions and plugins.

Enforce consistency and best practices

Guarantee best practices across all your APIs by running Buf's Protobuf linter and automatically reformatting files to correct violations.

Invoke gRPC and Connect APIs with ease

Call your gRPC and Connect APIs using Buf's cURL-like interface which automatically handles headers and message-enveloping while providing a readable JSON representation of binary responses.
