Buf Rate Limits

Published rate limits for the public Buf Schema Registry at buf.build. Limits apply to ALL traffic regardless of plan; Pro (.buf.dev) and Enterprise dedicated instances are not rate limited under current configuration, which is where Buf says high-volume production workloads usually run.

Buf Rate Limits is the machine-readable rate-limit profile for Buf on the APIs.io network, in the API Commons Rate Limits shape.

It captures 4 rate-limit definitions.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers.

Tagged areas include Code Generation, gRPC, Kafka, Open Source, and Protocol Buffers.
