Installation
OpenOnyx is a desktop app for macOS, Windows, and Linux. Install it, then choose a folder. No account is required for local writing.
Why it exists
The desktop app gives Markdown files a fast editor, graph, canvas, and thinking layer without moving them into a hosted database.
When to use it
Install OpenOnyx when you want a local workspace for an existing folder or a new personal vault.
Workflow
Download → install → launch → choose a folder → create a note.
Install
| Platform | Package |
|---|---|
| macOS | .dmg or .zip |
| Windows | .exe installer or portable executable |
| Linux | .AppImage, .deb, or Arch package |
Get the current build from GitHub Releases.
OpenOnyx tip
Keep the application and your vault separate. Updating OpenOnyx should never replace your notes.
OpenOnyx common mistake
An installer changes the application, not your vault. Open a vault only after you know which folder you intend to use.
