Swarm Lab

Tens of thousands of agents, simulated end-to-end on your GPU in WebGL2. Eight modes, each a faithful implementation of a landmark paper in collective behavior and active matter — and the order parameters are read back from the GPU, so you are watching the physics, not a decorative loop. Every mode links its source paper.

0 agents

Three local rules — separation, alignment, cohesion — produce coherent global motion with no leader.
