Hey everyone! 👋 I'm the creator of Recursive — a free tool that lets you paste your code and watch it execute step by step. Why I built this: I was studying algorithms and kept running into the same problem — I couldn't see what was actually happening inside my code. Print statements weren't enough, and debuggers felt too heavy for quick learning. So I built something where you just paste your code, hit run, and see everything visually.
