Stainless
Stainless is a New York-based developer-tools company that turns an OpenAPI specification into a portfolio of high-quality, idiomatic SDKs, reference documentation, MCP servers, CLIs, and Terraform providers. The platform was founded by veterans of Stripe, Heroku, and Twilio with the explicit goal of bringing Stripe-quality developer experience to any API, and is used by AI-platform and infrastructure companies including OpenAI, Anthropic, Google DeepMind, Cloudflare, Modern Treasury, Perplexity, Replicate, LangChain, Beeper, and Runway. Stainless supports nine target languages today (TypeScript, Python, Go, Java, Kotlin, Ruby, PHP, C#, plus a CLI) and publishes generated code under the Apache 2.0 license into customer-owned GitHub repositories. The company exposes its own platform as a REST API at api.stainless.com (v0), with endpoints for managing organizations, projects, branches, builds, and the current user, plus a build-compare endpoint and matching client libraries. Stainless also ships the Stainless Studio (web-based config UI), the Stainless CLI, a Language Server, GitHub member sync, breaking-change detection, SSO, audit logs, and integrations with documentation hosts (Bump.sh, GitBook, Mintlify, ReadMe).
