CodeViz runs your real DSA code and lets you step through execution line by line — not a fake animation. Write in Python, JS, Java, C, C++, C#, or Go. Hit Visualize and see: • Which line is running • Variables changing step by step • Arrays as bar charts • Program output as it runs Build a private question library with starter + solution code per language. Mac desktop app + web beta. Free during early access.
Hey Product Hunt 👋
I built CodeViz because reading algorithm solutions wasn't enough — I needed to see what i, j, and the array were doing at each step.
Unlike visualizers that replay pre-made animations, CodeViz instruments your actual code and returns a real execution trace. Works in 7 languages today.
What you get:
→ Monaco editor + step-by-step playback
→ Variable diffs (amber highlight when values change)
→ Array bar charts when your code uses arrays
→ Your own private question library
Still early — graph view is text-based, linked lists/trees coming next. Would love feedback on what to prioritize.
Try it free, no credit card. Let me know what you think!
