Stainless

Stainless is a tool for generating client SDKs from OpenAPI specifications, built for API providers who want to offer developers ready-to-use libraries instead of asking them to write API clients by hand. It turns an OpenAPI spec into production-ready SDKs across languages. What Stainless does Generates native client libraries automatically from an OpenAPI specification Builds rich type systems for the generated SDKs Implements intelligent auto-pagination for endpoints that return paged results Adds retry logic to handle transient request failures Handles authentication for API requests within the generated SDK Who uses Stainless Stainless is used by teams that maintain a public or internal API and need to distribute SDKs to the developers who consume it. Rather than hand-coding and maintaining client libraries for each supported language, these teams keep their OpenAPI spec up to date and let Stainless produce the corresponding SDK code, including type definitions, pagination handling, retries, and authentication logic. In a maker's workflow, this shifts SDK maintenance from a manual, language-by-language task to a byproduct of keeping the API specification current, freeing engineering time for the API itself rather than the client libraries built on top of it.
