Tool profile
API platform for generating SDKs, docs, and MCP servers from an API source of truth.
SDK generation
Stainless belongs in the catalog because it represents a more productized approach to API developer experience than writing SDKs and reference docs by hand. The official site positions it around generated client libraries, API documentation, and MCP servers, which makes it highly relevant for platform teams that want consistency and speed across their developer-facing surfaces.
The product is also commercially legible. Its public pricing page exposes a free tier and paid generator-based pricing rather than forcing every buyer into a pure sales motion. That matters editorially because it lets teams evaluate whether generated developer interfaces are worth paying for before they make a broader platform commitment.
Quick fit
Editorial take
Stainless should be judged on whether generated developer interfaces reduce enough manual maintenance to justify platform spend. It is strongest when SDKs and docs are business-critical surfaces, not side tasks.
