ReactGrind

Hey Everyone

I'm Astik, a solo full-stack dev, and I built ReactGrind a LeetCode-style platform, but instead of reversing linked lists, you're solving real React problems: building components, managing state, fixing broken hooks, debugging re-render issues, etc.

Why I built this:
I kept noticing a gap tons of platforms train you for algorithmic interviews, but almost none train you for the actual React problems you'll face in interviews and on the job. So I built ReactGrind from scratch (A Sandpack, running live in-browser) to fix that.

Because building products has become much more accessible thanks to AI, the bar has had to rise a bit, or at least the expectations have become stricter.

I built my own tool  SafeLimit, but personally, I wouldn t launch it on Product Hunt yet because it s still very basic and doesn t even have a website.

I built ReactGrind because every time I prepped for React interviews, I ended up solving generic DSA problems on LeetCode that had nothing to do with what I'd actually be asked hooks gotchas, state management bugs, re-render performance, compound components.
