Generate
best-in-class SDKs.
Developers expect your API to come with a typesafe client library in their language.
With Stainless, you can deliver idiomatic SDKs while you stay focused on building the API.
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.
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.
“Stainless isn’t just taking our OpenAPI Spec, generating a bunch of code, and passing it along.
They’re exhibiting a strong sense of ownership over making sure it’s best in class and solves problems.”
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.”
