Grinding LeetCode teaches you to pattern-match memorized solutions, not to actually see how algorithms work. TraceCode is different, you step through real code, watch state change live, and do drills that make you predict what happens next. Fewer problems, deeper understanding, better interviews.
TraceCodeLearn algorithms by watching them run

Hey PH! 👋 I built TraceCode because I'm a visual learner. I'd grind LeetCode and my eyes would glaze over solutions I didn't actually understand, I was basically pattern-matching, not learning. One of those nights, I pasted an algorithm into Claude and asked it to help me visualize what was happening, some weird DP recurrence, and it clicked instantly. I thought, "what if this existed for every...
