Raising the bar

on REST

Stainless is building the platform
for high-quality, easy-to-use APIs.

Our mission

APIs are at the heart of all internet software, but right now they’re messy, chaotic, and hard to get right.

We're on a mission to build great open-source standards and tools that bring the benefits of GraphQL (types, field selection/expansion, standards) and gRPC (types, speed, versioning) to the simplicity and ubiquity of REST.

Bringing Stripe-quality SDKs to companies of all sizes

Stainless Founder Alex Rattray worked at Stripe where he designed and co-built the API developer experience that would go on to become the quality standard of the developer community. He created Stripe’s patent-pending client library codegen system and shipped TypeScript for the Stripe API.

After Stripe, Alex kept getting asked how to replicate the Stripe developer experience. Everyone understood they needed great SDKs, but only huge companies could afford the engineer-years it’d take to build a decent codegen system to make them. Frustrated with the available options, he started Stainless to bring the quality of Stripe's codegen to companies of any size.
