Robust & polished SDKs
Great SDKs for your API drive faster integration, broader feature adoption, quicker upgrades, and trust in your engineering quality.
At Stainless, we work hard to make each SDK feel as though it were hand-written by an expert in the language who had the time to get it right.
All our libraries include: rich types (for autocomplete and docs on hover), auto-pagination, auto-retry with backoff, seamless auth, and much more.
Provide your OpenAPI spec
All Stainless needs to get started is your OpenAPI spec. It doesn’t have to be perfect.
We’ll create a starter Stainless config file that standardizes naming and defines core functionality like pagination and authentication.
Generate your SDKs
Receive shippable SDKs in the languages your developers demand.
Iterate & customize
You can customize the Stainless configuration for more bespoke SDKs that best represent you and your developers by fine-tuning names, docs, and more.
Add any custom code, anywhere
Unlike other codegen systems, you can freely edit the generated code as if it were a normal repo – any change, anywhere in the codebase. Your changes will persist the next time Stainless generates a new version.
Automate your updates
Push your updated OpenAPI spec to us whenever it changes with a GitHub Action (or equivalent). We regenerate your SDK and open a pull request.
“Proud to have Stainless as a partner at OpenAI. All our SDKs are generated by them. The team is extremely thoughtful about SDK design and push us to improve our API + other products while they're at it. Stainless is bringing a new standard of SDKs to our industry and this is a great thing for all developers.”
Stainless: the API Company
You can think of us like Stripe's API platform for any REST API, but our ambitions are a little bigger, and our starting point is a little narrower.
Know when the framework launches
We’re building a full-stack TypeScript API Framework. It’s inspired by the internal API Framework we used at Stripe, and will enable you to build amazing REST API’s from the get-go with end-to-end type safety, pagination, auth, and more built-in.
“If I told an engineer they have to build all these libraries, they’d tell me it would take at least a year. With Stainless, it’s like magic.”
