Buf

aid: buf
name: Buf
description: >-
  Buf is a modern developer platform for Protocol Buffers and gRPC, providing
  a CLI toolchain, schema registry, and streaming infrastructure. It replaces
  traditional protoc-based workflows with linting, breaking change detection,
  code generation, remote plugins, and the Buf Schema Registry (BSR) for
  centralized schema distribution. Buf also offers Bufstream, a Kafka-compatible
  streaming platform built on Protobuf. Used by enterprises including EA, Intel,
  IBM, OpenAI, and Okta.

    description: >-
      The Buf Schema Registry (BSR) is a centralized repository for managing,
      distributing, and documenting Protobuf schemas. It provides dependency
      management, generated SDKs in multiple languages, remote plugins for code
      generation, and a Reflection API for runtime schema discovery.

      The Buf CLI is a local Protobuf development toolchain providing linting,
      breaking change detection, code generation, formatting, dependency
      management, and schema push/pull to the Buf Schema Registry. It replaces
      protoc with a faster, more developer-friendly interface.

      Bufstream is a Kafka-compatible streaming platform built on Protocol
      Buffers. It provides schema enforcement, Iceberg integration, and
      administrative tooling for managing Kafka-compatible streaming workloads
      with Protobuf as the data format.
