Points that share space as cells, inside any shape
Open Voronoi · Run it · More tools
Every point holds its territory. Give one more weight and it pushes the borders; relax them all and the cells settle into a honeycomb.
Open robvagin.github.io/voronoi, or download index.html and open it from your disk. It is the whole tool: no build step, no dependencies, no network. Press H to hide the panel.
I'm a designer. I build small tools like this for my own work, with AI agents: I make the decisions, Claude Code writes the code. The panels follow one grammar across the whole set.
