Overview

Buf.build provides a platform focused on API development, specifically utilizing Protobuf, gRPC, and Kafka technologies. Its main product, the Buf Schema Registry (BSR), allows teams to manage and collaborate on Protobuf schemas across different repositories, making it easier to work on the foundational elements of their software. This platform includes features such as API discovery, documentation browsing, and code generation management, which help streamline the development process.

The company's goal is to simplify and improve the API development process for tech teams of all sizes.
