Speakeasy

What is Speakeasy?

Speakeasy is an OpenAPI-native developer platform that automatically generates production-ready, idiomatic, type-safe client SDKs from an API's OpenAPI specification, eliminating the slow, error-prone work of hand-writing and maintaining SDKs in many languages. 0 authentication, retries, pagination, error handling, and generated documentation.

Beyond SDKs, Speakeasy can generate Terraform providers, command-line interfaces, contract tests, and Model Context Protocol (MCP) servers, positioning itself as a control plane that makes APIs equally usable by human developers and AI agents.

It integrates into CI/CD via a GitHub Action so SDKs are regenerated, versioned, and published automatically whenever the spec changes, keeping client libraries in sync with the API.

Typical users are API platform teams and companies that publish public or partner APIs and want polished, maintained SDKs without dedicating engineers to each language. Pros include high-quality idiomatic output, broad language coverage, and automated publishing pipelines.

Cons include that you need a well-maintained, accurate OpenAPI spec to get good results, and advanced features and higher SDK counts require paid plans. Teams with highly unusual API patterns may also need extra configuration to get the exact output they want.

Pricing is freemium with paid tiers scaling by SDKs and features. Pricing changes often, so check the official site for current plans.
