Try Algo Viz exists because static pseudocode doesn't cut it. We believe the fastest path to understanding any algorithm is seeing it run — live, in front of you, with your own inputs.

Most people learn algorithms from textbooks — walls of code, abstract notation, and no feedback loop. They memorize patterns for interviews and forget them a week later.
We built Try Algo Viz to flip that model. Every algorithm here can be driven by you: set your own inputs, step through frame by frame, or run it at full speed. The mental model builds itself.
Whether you're prepping for a FAANG interview, taking your first DSA course, or revisiting concepts you thought you knew — this is your lab.
Watch every swap, comparison, and traversal happen live on-screen. No guesswork — just crystal-clear step-by-step logic.
Every visualizer ships with a synchronized code panel so you can map each visual state to its corresponding line of code.
Six hand-crafted themes — from Neon dark to Ocean light — designed so learning feels as good as it looks.
From Bubble Sort to Dijkstra's, 0/1 Knapsack to N-Queens — we cover the full spectrum of algorithms you'll actually need.
Each visualizer has a built-in learn guide explaining the "why" behind every algorithmic decision, right in context.
Jump straight to any algorithm or sub-technique with the keyboard-first global search. No hunting through menus.
All 11+ modules are free, no account required. Just pick an algorithm and dive in.
