> Open-source documentation platform for Markdown and MDX with search and AI chat

Tome is an open-source documentation site builder built with React, Vite, and Hono. It converts Markdown, MDX, and Markdoc into fast documentation sites featuring full-text search, API playgrounds, and AI assistant widgets. It serves as a self-hostable alternative to paid tools like Mintlify without expensive monthly subscriptions.

## Why it was saved

- [@vec0zy, 12 March 2026](https://x.com/vec0zy/status/2032221668341395700): Positioned as a free/open alternative to Mintlify's $200–600/month tiers — the author was quoted $250–300/month for a second docs project and built this instead in three days.
