Tools

1. Editor

   Monaco (VS Code) editor with autosaved tabs, diff view, and open & save of real files via the File System Access API.

2. Draw

   Infinite canvas whiteboard powered by tldraw. Shapes, arrows, freehand, text, image export, autosaved locally.

3. Topology

   Build network topologies: draw devices and the ports between them, or generate a 2-tier / 3-tier fabric from a form, then lay it out, style it and teach from it. Everything runs in your browser: nothing you enter is uploaded anywhere.

4. Animator

   Animate a journey across a topology you drew in Topology. Click out the stops, write what happens at each one in your own words, and play it back. Animator reads no meaning into your diagram, so it fits a mobile core as readily as a campus.

Everything you make in these tools stays in this browser. You can save a backup of all of them at once, and read it back here or in the desktop app.
