Hey everyone! I just launched TraceLit on Product Hunt.
TraceLit lets you paste your Python code, enter a test case, and step through execution line by line while
watching linked lists and binary trees transform as interactive node graphs.
Built it because I kept losing track of pointers when dry-running on paper. Now I can see exactly where
Hey everyone! 👋
Visualizing pointer logic in your head is hard. That’s why I created TraceLit—a visual execution tool designed to help you ace those tricky data structure interviews.
What makes it different?
Visual Execution: Watch nodes and pointers move in real-time as you step through your Python code.
Interactive Graphs: No more static diagrams; see exactly where your head, curr, and null pointers are.
AI Debugging: Get instant explanations for root causes when your code fails.
It’s live, free, and needs no sign-up: tracelit.dev.
I’m curious to know: Would this have helped you in your last technical interview? Also, let me know which languages or data structures you’d like to see added!
Can’t wait to hear your feedback! 🙌
