Draw: Click and drag to place walls. Shift+click for weighted nodes (5x cost).
Place: Right-click twice to set start and end points.
A* (Manhattan): Uses Manhattan distance heuristic. Guarantees shortest path when diagonal movement is off.(respects weighted nodes)
About this tool: All algorithms run client-side with zero dependencies.
Click to draw walls, Shift+click for weighted nodes (5x cost), right-click to place start/end.
Generate mazes and compare how different algorithms explore the grid.
