Show, don't
tell
Write code, watch it execute. See arrays fill, loops iterate, and variables change — step by step, in real time. Built for learners who want to understand, not memorize.

Here are some ways code visualization can elevate your learning, teaching, and sharing.
Build a better homepage demo
Embed a live visualization of your algorithm right on your landing page.
Add to changelogs or blog posts
For every new DSA concept, show how it works with interactive step-through.
Tweet an Arcade
Share interactive algorithm visualizations directly on social media.
Embed on your solutions page
Create an interactive visualization for each DSA topic — arrays, trees, graphs.
Create visualizations on the fly
Build custom step-by-step code walkthroughs to explain any algorithm.
AI explains every step
Our AI tutor breaks down each execution step in plain, simple language.

3 for(int j=0; j<n-i-1; j++) {
4 if(arr[j] > arr[j+1]) {
5 swap(arr[j], arr[j+1]);
