Our mission is to bring the best of GraphQL and gRPC to the simplicity and ubiquity of REST.
Our business model is to offer a suite of developer platform products to enable every company to offer the kind of developer experience Stripe does around their API.
Our first product is API client libraries as a service – you send us your OpenAPI spec, we let your customers npm install your-company
