Developer platform for Protocol Buffers providing schema registries, linting, breaking change detection, and RPC tooling.
Buf is a San Francisco-based developer infrastructure company building tools and a cloud platform around Protocol Buffers (protobuf), the binary serialization format widely used in gRPC-based APIs and microservices architectures. The Buf CLI provides linting, formatting, and breaking change detection for proto schemas, enabling teams to enforce style consistency and prevent API changes that would break downstream consumers. The Buf Schema Registry (BSR) serves as a central repository for proto schemas across an organization, enabling schema sharing, dependency management, and generated SDK distribution — solving the version management problem that has long plagued large organizations using protobuf. The company's Connect framework provides a modern alternative to gRPC that works natively with browsers, eliminating the need for a gRPC-web proxy. Founded in 2020 by former Uber engineers, Buf raised over $65M from investors including Accel, Tiger Global, and The General Partnership. It has become the standard toolchain for protobuf workflows in organizations ranging from startups to large enterprises.
