OMN-Go

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 at https://github.com/mvbasov/OMN-Go/releases - the same notes and the same interface. Optional git synchronization keeps a desktop device and a phone in step.

I tried to describe as much as possible in the built-in documentation. Please read it.

I design this application to my needs and use it everyday for several years. I will be glad if this application meets anybody needs also.
