Speakeasy reads a Swagger/OpenAPI spec file and generates typed SDKs in multiple languages from it automatically.
→ Production-quality SDKs auto-generated from the API spec — when the spec changes, the SDK regenerates without manual work.
Fern reads OpenAPI/Swagger specs and generates idiomatic client SDKs and server stubs from them.
→ Client and server code generated from the API contract — spec drift between code and docs becomes structurally impossible.
Stainless reads OpenAPI/Swagger specs and generates polished, production-ready SDKs with retry logic, pagination, and type safety.
→ Enterprise-grade SDKs auto-generated from the Swagger spec — the same quality as handwritten Stripe or OpenAI SDKs.
OpenAPI Generator reads Swagger/OpenAPI specs and generates client SDKs and server stubs across 50+ languages.
→ Broad language coverage from one spec — generate clients for any consumer language without maintaining them manually.
