Boids — Flocking Sim

A boids simulation demonstrates flocking behavior using simple algorithmic rules that mimic how birds move together. Watch as individual agents follow three key rules—separation (avoid crowding), alignment (match heading), and cohesion (move toward the group)—to create emergent swarm patterns. This free browser-based tool visualizes how complex, coordinated group behavior emerges naturally from local interactions between individuals, making boids simulation both intuitive and visually engaging.

Scatter the swarm and observe how it self-organizes in real time. The flocking simulation runs entirely in your browser with no signup required—just load the page and start interacting. Your data never leaves your device; everything happens locally for instant, responsive visualization of the emergent behavior. Adjust parameters, pause and resume, and watch the swarm react dynamically to your changes without any server connections.

Ideal for exploring swarm intelligence, this tool brings the classic boids algorithm to life with an interactive visual interface. Tweak simulation parameters, pause and restart at any time, and watch the swarm adapt and reorganize before your eyes. It's perfect for education, research, casual exploration, or developing deeper understanding of how natural flocking behavior emerges in birds, fish schools, and other coordinated animal groups.
