rspress

Rspress is a static site generator built on Rust-powered tooling (Rspack) that compiles your Markdown into a blazing-fast React site. It's Docusaurus but with build times that don't make you reconsider your career.

It uses MDX, supports full-text search out of the box, has i18n, and generates an optimized site with automatic code splitting. The developer experience is solid: hot reload is near-instant because Rspack (the Rust bundler underneath) handles the heavy lifting.

MIT. Fully free. No paid tier, no cloud service, no account. Build your docs site and deploy it wherever you want.

The catch: it's emerging. The ecosystem is tiny compared to Docusaurus . Fewer themes, fewer plugins, fewer community answers when you get stuck. If you need extensive customization beyond what ships out of the box, you're on your own. And the ByteDance backing (web-infra-dev) means long-term governance isn't community-driven.
