Build and test live APIs
quickly and confidently
Build, test, and iterate on your APIs in real-time without worrying about data serialization.
Create, test, and share API invocations
Leverage Buf Studio's autocomplete for APIs stored in the BSR to write and test API calls to staging environments, customize headers, inspect and save responses, and share invocations with teammates.
Invoke gRPC and Connect APIs with ease
Call your gRPC and Connect APIs using Buf's cURL-like interface which automatically handles headers and message-enveloping while providing a readable JSON representation of binary responses.
Integrate gRPC and Connect APIs with lightweight SDKs
Accelerate development with the suite of Connect libraries which provide first-class support for the gRPC, gRPC-Web, and Connect protocols in TypeScript, Swift, Kotlin, and Go.
Built on top of time-tested HTTP libraries, they generate lightweight, idiomatic APIs and enable engineers to build and collaborate quickly and effectively.
Enhance Protobuf data readability
Introspect Protobuf binary responses by easily converting between the binary and JSON formats.
Collaborate using draft API packages
Quickly iterate on proposed APIs by integrating generated draft packages on clients and servers during development using NPM, Maven, and more.
