Stainless generates idiomatic, production-ready SDKs in multiple languages from an OpenAPI spec, eliminating the manual work of building and maintaining client libraries.
Stainless is a developer tools company founded in 2022 that automates the generation of high-quality, idiomatic API client SDKs from OpenAPI specifications. The company addresses the significant engineering burden of maintaining accurate, well-designed SDK libraries across multiple programming languages like Python, TypeScript, Java, Go, Ruby, and Kotlin. Stainless generates SDKs that include features like pagination, retries, streaming support, and type safety that are difficult to implement consistently by hand. The company is used by notable API companies including OpenAI, Anthropic, Cloudflare, and Stripe, which have used Stainless to generate or improve their official SDK libraries. Building and maintaining SDKs across multiple languages is a hidden cost for API-first companies that can consume significant engineering capacity, and Stainless turns this into a solved problem. The company raised significant seed funding and has built a reputation for producing SDKs with the polish and ergonomics of hand-crafted libraries while eliminating the ongoing maintenance work as APIs evolve.
