Detailed overview

Speakeasy turns OpenAPI descriptions into production-ready SDKs, documentation, and related API tooling. Teams can generate client libraries in several popular languages, customize the generated output with configuration and overlays, and publish updates as their API evolves. Its workflow is designed for API producers who want consistent developer experience without hand-maintaining every client library. Speakeasy also provides tools for testing generated SDKs, managing breaking changes, and integrating generation into source control and CI workflows. The platform can fit organizations that expose public APIs as well as internal platform teams standardizing service interfaces. It is more specialized than a general code generator because its central workflow depends on an API description and generated artifacts. Teams should confirm language, runtime, publishing, and governance needs against the current documentation before adopting it.
