Stainless
Stainless generates idiomatic client libraries in seven languages, documentation that tracks the API, and MCP servers, all derived from an OpenAPI specification. Its homepage announces that the company is joining Anthropic.
- Removes SDK drift structurally rather than through discipline
- Idiomatic output is the specific failure that discredited older generators
- Seven languages is coverage most API teams cannot maintain by hand
- Documentation generated from the same source cannot describe a stale endpoint
- Everything inherits any error in your OpenAPI specification
- Unusual interfaces may not express cleanly in a spec
- The Anthropic announcement leaves continuity questions unanswered publicly
