DeetCode is now open source
12.07.2025
I built DeetCode a while ago.
It was inspired by NeetCode, LeetCode, and Back to Back SWE, the few of many “leetcoding” platforms where I used to learn algorithms and data structures.
I thought it would be cool to build something similar, with a visualization feature to it.
Initially, it was meant to be a social coding site, where users could share solutions.
But it never quite took off.
So I converted the entire thing into a static site. This was a fairly quick process with the help of AI and Next.js Static Site Generation.
DeetCode is now open source. You can find the GitHub Repo here:

And the static site is now deployed here on GitHub pages:
