Buf vs Ankr
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.
Decentralized Web3 infrastructure with RPC node access across 30+ blockchains; globally distributed nodes reduce latency; premium dedicated nodes for apps needing guaranteed throughput.
About
Ankr is a Web3 infrastructure platform offering remote procedure call node access to more than 30 blockchain networks through a globally distributed network of nodes run by independent operators. Unlike centralized providers that operate their own data centers exclusively, Ankr's decentralized architecture routes requests across geographically distributed nodes, improving latency for users in regions underserved by US- or EU-centric infrastructure. Its public free-tier RPC endpoints — available for Ethereum, BNB Chain, Polygon, Avalanche, Fantom, and dozens of others — have made Ankr one of the most widely used infrastructure providers in the multi-chain developer ecosystem.
