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

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.

We launched SDKs—here’s how we’ll keep them correct

As a billing data platform, our web API is the primary surface area that technical folks interact with; compared to raw cURL commands, SDKs in your language of choice can lead to a much better developer experience, and make it quicker to get up and running. Our API is ever-evolving and handwritten SDKs could fall out-of-date (especially in languages we don’t use regularly in-house).
