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!
