ReadMe

ReadMe is the established interactive API documentation platform: OpenAPI specs become beautiful reference docs with a live try-it-out explorer, versioning, changelogs, and guides. Its differentiator is the Developer Dashboard — endpoint-level analytics showing which developers call what, where errors cluster, and where adoption drops off, powered by a Metrics SDK you embed in your backend. Recent additions include a one-toggle hosted MCP server generated from your docs so AI coding assistants can list endpoints and call your API. A free Starter tier covers personal projects; paid plans scale to Enterprise with SSO, staging environments, and private APIs.

The honest picture: the realistic entry point for teams has crept up — recent comparisons put Pro around $250/month billed annually, with the AI chat assistant a $150/month add-on. The renderer is closed and hosted-only (no self-hosting), and the analytics only appear once you integrate the Metrics SDK. Teams wanting an open-source docs renderer should look at Scalar or Redoc instead.

Sign up at readme.com, create a project, import your OpenAPI spec (or sync from GitHub), and publish. Embed the Metrics SDK in your API backend for analytics.
