Building a Chrome Extension to Make LeetCode Prep More Practical
Source: Dev.to
The idea
Build a simple Chrome extension that shows company tags directly on LeetCode problem pages, inside the LeetCode UI itself.
- No new tabs.
- No distractions.
- Just information where it’s needed.
Get it on GitHub: LeetCo Here

What I built
The extension injects a small UI block below the problem title and displays:
- Companies that have asked the problem
- Interview relevance at a glance
The goal isn’t to replace LeetCode—just to make practice more intentional.

Feedback welcome
This started as a learning exercise, but I’d love feedback from:
- People who’ve built Chrome extensions
- Anyone doing interview prep
- Developers who enjoy building small productivity tools
Suggestions, issues, and PRs are always welcome.
Thanks for reading — and happy LeetCoding 🚀
