Free, open-source, and battle-tested by half of GitHub's OSS projects — the safe default for docs-as-code.
The default pick when you want docs that read like a real product, not a wall of Markdown.
Point it at a GitHub repo and get a polished, AI-searchable docs site without touching a CSS file.
Already on Next.js? This gets you a fast, MDX-powered docs site without adopting a second framework.
If your product is an API, this turns your OpenAPI spec into docs devs can actually test requests against.
Docs that live next to your code and flag themselves as stale in CI when the code moves on without them.
The generator Vue and Vite use for their own docs — lean, fast, and Markdown-first for Vite-based projects.
