Moebius Screenshot


Moebius is an ANSI Editor for MacOS, Linux and Windows. The major feature that differentiates it from PabloDraw is the 'half-block' brush which allows editing in a style closer to Photoshop than a text editor, although you can still use the function and cursor keys to draw with, and you should find that most of the text editing features from PabloDraw are carried over to this editor. The editor is still a work in progress, but anyone who wants to try using it is also encouraged to log feature requests and bugs on the project's GitHub page.

Download packages

Packaged binaries are available through Github Releases or from the direct links below:

Installation & building

git clone
npm install
npm start

Moebius packages can be built easily with electron-builder. Note that a build for MacOS must be made on MacOS.

npm run-script build-mac
npm run-script build-win
npm run-script build-linux

Moebius Server

Moebius features collaboration by multiple users on the same canvas through a server instance. Users connect to a server which allows them to draw and chat. The server will also create hourly backups.

To start a server:

git clone
npm install
node ./server.js

This will start a server with default settings. In this case a password will not be set and any value entered in the Moebius client will be accepted by the server. The server runs by default on port 8000, Moebius clients can modify the port by entering the server as hostname:port

The following parameters can be set:

  • --file=filename.ans load an initial ANSI file after the server starts
  • --pass=password set a server password which clients need to provide to logon to the server
  • --server_port=8000 set the server port, defaults to 8000.
  • --web and --web_port=80 run the webserver for external viewing (default port: 80). This enables live preview of the canvas, the preview and SAUCE information in a browser, the URL would be http://hostname.tld:web_port
  • --path=pathname set a path for this server: users and webviewers would connect to hostname.tld/path
  • --quiet=true/false suppress console output after the server has been started
  • --discord=url Mirrors server joins and chat activity via a Discord Webhook
