OMN-Go is a self-hosted personal wiki and note application that uses Markdown. It runs a small local web server on your device and shows your notes in a browser-style interface. It needs no account, no cloud service, and no third party to keep working. A note is a plain Markdown file with a small header block (title, date, tags). OMN-Go compiles each note to a static HTML page. You can read these pages and link between them with ordinary relative or absolute links. Key features: • Full Markdown editing, with the built-in editor or your preferred external text editor. • Optional git synchronization over SSH, so the same notes stay up to date on every device that runs OMN-Go. OMN-Go shows each conflict clearly and gives you a manual merge or a safe pull or push. • Optional LAN sharing, off by default. In the default state, OMN-Go answers only local connections. If you enable LAN sharing, other devices on your network can reach your notes over HTTP with a password. This is useful to read or edit from a second device without git synchronization. • An embedded SQL database that note scripts can read and write directly. You can create a backup of its contents at any time. Git can track this backup, and OMN-Go saves it with your notes. • Quick capture: a quick-note box that opens with one press, and a bookmark collector. Both work with the Android share-to-application function. • The Tags page, which OMN-Go generates automatically. It indexes every note by its tags and works offline. • On Android, a note can open a system settings screen or start another application. It can also run a Termux command. These links use an intent: URI, and the function is off by default. • Math formulas (KaTeX, opt-in per page) and automatic syntax highlighting for fenced code blocks. • Light, dark, and system-following themes. • Material Design icons and small HTML/JS building blocks that you can put into any note. OMN-Go also runs on the desktop. You can get the Linux and Windows builds
