DocuCommit is a self-hosted documentation platform that stores every page as plain Markdown in your own Git repository. There is no database: every edit is a real commit, so revision history, diffs, and restore come from Git itself, not from a vendor's revision table.
Non-developers get a WYSIWYG editor that writes clean Markdown (toggle to source anytime), a guided three-pane merge when two people edit the same page, and paragraph comments stored in a sidecar file so the Markdown stays clean. Developers get files they can grep, and AI agents can read the entire knowledge base with a git clone. No integration layer, no sync pipeline.
Includes full-text search, draw.io and Mermaid diagrams stored next to the Markdown, and one-click export to Markdown, HTML, and PDF. A desktop app for editing, plus a read-only server (Docker) that publishes the docs to the whole team. Leaving costs nothing: the repo is already yours, so there is nothing to migrate out of.
A startup from Sweden.
