About

Platform that generates client SDKs, MCP servers and API documentation from an API specification.

Stainless generates client libraries, MCP servers and API documentation from an API specification, so API companies can ship SDKs in several languages without hand-writing each one. Generated SDKs cover areas such as auth, headers, webhooks, streaming and async.

The docs product supports custom domains, custom JS and CSS, AI chat and password-protected docs, with Git as the source of truth. A Free plan includes up to five generators and five seats for APIs up to 25 endpoints, with Starter, Pro and Enterprise plans above it.

Key features

SDK generation in multiple languages; MCP server generation; API documentation with custom domain; Git as source of truth; Preview builds in CI; Unit tests for generated SDKs; AI chat in docs
