Buf vs Postman
Side-by-side comparison of AI visibility scores, market position, and capabilities
Buf is a developer platform for Protocol Buffers with CLI linting, breaking change detection, a Schema Registry, and generated SDK distribution — simplifying gRPC API governance at scale.
About
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.
World's leading API development platform with 30M+ developers; $433M raised at $5.6B valuation competing with Hoppscotch and Apidog after 2023 developer backlash over mandatory account requirements.
