OpenAPI to SDKs + docs

Ship API docs and SDKs from one OpenAPI spec.

Upload OpenAPI. Review the generated TypeScript + Python SDKs, hosted docs, and release checks — then publish when everything passes.

Unlimited previews and up to 2 hosted docs review sites. No credit card required.

Docs that never drift from the spec

Every generation produces a hosted docs preview — versioned routes, per-operation pages, runnable examples, and llms.txt — at a private noindex URL your team reviews before anything is public.

API documentation tools

SDKs your customers will actually use

Typed TypeScript and Python clients generated from the spec, smoke-tested on install, and published to npm and PyPI only after a dry-run passes and an owner approves.

OpenAPI SDK generator

Every change reviewed before it ships

Spec diffs become a changelog with added, changed, and removed operations. Nothing reaches a registry, repo, or production domain without an explicit approval step.

How releases are gated

Agent tools from the same spec

Generate a reviewable MCP server and connector pack — tool inventory, safety report, and client files for ChatGPT, Claude, and Grok — from the OpenAPI you already maintain.

MCP server generator

Built for

Teams that ship an API as a product.

API platform teams

Replace hand-maintained SDK repos and docs plumbing with one reviewed pipeline from the spec you already own.

DevRel and docs owners

Hosted reference docs with examples that stay correct, plus a WYSIWYG editor and private review links for every change.

Teams shipping agent tools

MCP servers and connector packs generated alongside the SDKs, with a safety report before anything is exposed to an agent.

Replacing Stainless, Mintlify, Speakeasy, or Fern?

Sourced imports your existing config, reports feature-by-feature compatibility, and previews every SDK and docs change before customers see it. The comparisons below are maintained against public docs and pricing.

Free previews. Pay when you go live.

Unlimited SDK and docs preview generations, plus up to 2 hosted noindex docs review sites, free — no credit card. Paid plans start when you publish to npm, PyPI, GitHub, or a custom docs domain.
