Watch Algorithms Think.
Interactive, step-by-step visualizers that transform abstract algorithms into cinematic experiences. Built for engineers who want to understand, not just memorize.
Code Tracer
Paste any JavaScript. Watch it execute line by line with variable tracking, array visualization, and console output.
Pathfinding (A*, Dijkstra)
Visualize shortest-path algorithms on interactive grid mazes.
Binary Search Tree
Insert, delete, and traverse BSTs with animated node operations.
Graph Traversal (BFS/DFS)
Step through breadth-first and depth-first traversal on custom graphs.
The Engineer's Advantage
Reading about O(n log n) is one thing. Watching Quick Sort partition an array in real-time is another. These visualizers are designed for developers who want to build intuition — not just pass interviews. Every frame is a snapshot of the algorithm's state, giving you time-travel access to its decision-making process.
