What it does: - Paste a Python or JS/TS code or function and parameters are auto-detected - Step through execution line by line with variable tracking - Arrays are displayed as a grid with change highlighting - Recursive functions are visualized as a call tree - Embed the visualization in your blog or Notion
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.

Who hunted Recursive?
Recursive was hunted by Seonghyeon Kim. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
