Hubble.md turns local Markdown folders into searchable documentation sites
Hubble.md converts a local directory of Markdown files into a browsable, searchable documentation site, using automatic file-tree navigation and live reload for instant feedback. Created by Ben Holmes as a developer-focused utility, the tool uses the Astro framework for a high-performance interface. It offers zero-configuration setup, global search, syntax highlighting, and frontmatter support, so developers, technical writers, and students who keep local notes can browse and find content without moving files off their machine.
What the tool does and who benefits
Hubble.md builds a local documentation site from a folder of Markdown. It reads the directory structure and presents files as a navigable tree while indexing content for search. This makes it useful for people maintaining README collections or knowledge bases who need quick access to many local notes. The tool targets developers and technical writers who prefer local-first workflows and want documentation visible in a browser rather than a raw file explorer.
How it interacts with your system during use
Hubble runs as a Node.js-based local server that serves files to a browser. It requires Node.js version 14 or higher, and you typically launch it from the command line (for example, via an npx invocation). Because it serves content locally, CPU and memory use follow typical development servers; the Astro foundation is chosen for fast page rendering and low-latency navigation.
Safety, privacy, and operational simplicity
Hubble.md keeps content on your machine and avoids external uploads, providing local-first privacy by design. The tool follows a zero-configuration model so you don't need a setup file to generate the site. Built-in syntax highlighting and frontmatter support let you present code blocks and metadata without extra plugins, while live reload shows edits in the browser as you save files.
Who should run Hubble.md and when
Hubble suits developers and technical writers who prefer local control over documentation and can operate a CLI-based workflow. It trades setup flexibility for immediate, no-configuration previews, so it's less appropriate for users who need a hosted or integrated editing platform. For anyone organizing a local Markdown corpus and comfortable with Node.js tooling, Hubble is a concise, focused option. Recommended.
