MarkHub

In the AI era, documentation lives across multiple repositories and branches — design docs on feature-x, API specs on main, architecture notes on v2-refactor. MarkHub brings them all into a single, beautiful web interface.

Point it at any number of local repos and git refs to instantly browse Markdown files with live hot-reload, syntax highlighting, and a premium reading experience. Zero configuration, single binary, just run and read.
