ReadMe builds interactive API documentation that developers can read, test and search. You import an OpenAPI file by URL or upload, then write guides, recipes, a changelog and discussion forums in a WYSIWYG editor, in Markdown, or from your own IDE through bi-directional sync with GitHub and GitLab. An Ask AI search assistant, an AI Linter that enforces your style guide, and a built-in MCP server and LLMs.txt file keep the docs usable by AI agents as well as people. The Starter plan is free for one project with a custom domain, an interactive API reference and usage metrics. Pro costs $250 per month billed annually, and Enterprise is custom priced.
The product suits API companies, developer relations teams, technical writers and product managers who treat documentation as part of the product. Small startups can publish a branded docs site on the free Starter plan without a developer building a portal. Growing teams on Pro get multiplayer editing, branching and reviews, private docs and custom MDX components so several writers can work in parallel. Larger organizations use Enterprise for multiple combined projects, SSO, role-based access, audit logs and dedicated support. Engineers who prefer working in a repository can keep docs in Git and let writers edit in the browser.
Typical uses include launching a public API reference with a try-it console, writing step-by-step recipes that walk through common integrations, and publishing a changelog so customers see releases as they ship. Teams migrate existing docs from another platform by importing an OpenAPI file or Markdown, then review proposed edits on shared branches before merging. Companies add a help center or SDK documentation beside the API reference, connect Google Analytics, Segment, Slack or Zendesk, and use usage metrics to see which endpoints and pages developers actually read. An MCP server lets coding assistants query the docs directly.
