I'd been grinding LeetCode for months. The visualizer made me actually see what binary search does — suddenly it clicked. Two pointers, sliding window, all of it.

75+ algorithms with step-by-step animations and your own inputs.
Most tools give you one thing. We give you the full picture — from interactive visualizations to a structured learning path to CS theory.
75+ interactive visualizers brought to life. Pause, rewind, and step frame by frame. Inject your own data. Watch the exact line of code fire in real time.
A 17-phase gamified journey from star patterns and searching to advanced algorithms. Your avatar moves through unlockable phases. Earn achievements. Build streaks.
Three curated reading tracks — Operating Systems, Databases, and Computer Networks — with phase-by-phase progress and per-article completion.
Build streaks, master algorithms, and clear the CS-fundamentals paths — your profile keeps score and the badges roll in.
Master 5 algorithms.
Maintain a 7-day activity streak.
Master 25 algorithms.
Master every algorithm in the catalogue.
We don't show you slides. We put you in the driver's seat of the algorithm itself.
Pause, rewind, and step through any algorithm frame by frame. Build genuine intuition, not muscle memory.
See the exact line of code firing in real-time, synchronized perfectly with the on-canvas animation.
Don't just watch a demo — inject your own values, pick your own start nodes, and see how it behaves.
Learning without structure is just browsing. The roadmap keeps you on track — and makes the progress feel real.
Unlock stages in sequence. Your avatar moves through the roadmap as you complete each algorithm — satisfying, visible progress.

Real notes from students, working devs, and self-taught learners who watched TryAlgoViz click for them.
I'd been grinding LeetCode for months. The visualizer made me actually see what binary search does — suddenly it clicked. Two pointers, sliding window, all of it.
We use TryAlgoViz in our weekly office-hours sessions. Cleanest interactive visualizations I have seen, and the article alongside each one is exactly the right level.
First time I understood DP wasn't 'a thing only smart people get'. The grid animations for knapsack and LCS are like a switch flipping in your head.
Finally a tool that doesn't just throw code at you. The Run button is addictive — change the input, watch it work, get it intuitively. I keep coming back.
Follow the roadmap, visualize every algorithm, and build the CS theory underneath it all. Everything in one place, at your own pace.
