Blume is an open-source, zero-config documentation framework built on Astro and Vite that turns a folder of Markdown or MDX files into a production-grade docs site with no app boilerplate to write or maintain. It automatically infers navigation from your file structure and ships search, theming, Open Graph images, and SEO out of the box. Blume includes built-in AI features such as llms.txt generation, a hosted MCP server compatible with Claude Code and Cursor, an Ask AI assistant, and raw Markdown URLs for LLM consumption. The CLI handles scaffolding, dev serving, building, link validation, SEO auditing, and AI-powered doc evaluation in a single tool. Static output deploys to any CDN or static host, with server-mode adapters available for Vercel, Netlify, and Cloudflare Pages.
