Master Algorithms Visually
The most comprehensive algorithm visualizer for students, educators, and developers. Watch, compare, and understand 67 sorting and 28 pathfinding algorithms in action. Platform brought to you by Shard LLC.
Everything You Need to Learn Algorithms
The most comprehensive, free interactive platform for algorithm concepts
Real-Time Visualization
Watch algorithms unfold step-by-step with smooth animations. Follow comparisons, frontier growth, swaps, and path construction in real time.
Side-by-Side Compare
Compare strategies on the same problem setup. See how different approaches behave on arrays, grids, and constrained scenarios.
Step-by-Step Mode
Pause, step forward, step back. Ideal for understanding every decision point, transition, and state update.
Benchmark Mode
Run repeatable benchmarks with multiple trials and export results to CSV or JSON for analysis and classroom use.
Custom Code Editor
Prototype your own algorithm ideas, inspect the behavior, and share experiments with a simple link.
Purpose-Built Interface
Themed visuals, responsive controls, sound cues, and polished interactions keep deep technical learning approachable.

Built for Education
Whether you're a CS student cramming for exams, a professor preparing lectures, or a developer brushing up on fundamentals, this platform helps abstract algorithm ideas become concrete.
- ✔ Visual Memory: See algorithms operate on data, grids, and state changes instead of reading static traces
- ✔ Active Learning: Pause, inspect, rewind, and experiment at your own pace
- ✔ Compare & Contrast: Understand trade-offs between search, optimization, and ordering strategies
- ✔ Write Your Own: The best way to learn is by doing
