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.

What it's for

  • Build and host technical product documentation from Markdown or MDX files
  • Provide interactive API reference documentation with an OpenAPI playground
  • Add an AI search and chat assistant to technical docs using custom API keys
  • Expose an MCP server so external AI coding agents can read product docs

Features

  • Markdown, MDX, and Markdoc rendering support
  • Built-in full-text and semantic client-side search
  • Interactive API reference and OpenAPI playground
  • AI documentation chat widget supporting custom API keys
  • Custom domains with automatic SSL certificates and global edge caching
  • Pre-configured theme presets and custom styling options
  • MCP server integration for AI agent compatibility
  • CLI deployment workflow with zero-config preview environments

Pricing

Open source. Free and open source under the MIT license; self-hostable or deploy to Tome Cloud

Why it was saved

  • @vec0zy, 12 March 2026: 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.
