The editor
A tessellation editor that runs in your browser, mobile first; with desktop builds for dedicated work.
The Tessella editor lets you design simple-polygon tessellations, click by click. Pick a polygon, snap it to an existing edge, fan it around a vertex, mirror a region — and export the result as SVG or DOT. It runs in any modern browser, mobile first; native builds are available for macOS, Windows and Linux.
