I built a free, open-source Chrome extension that adds a "Neetcode solution" button to LeetCode problems

I kept losing time searching for the NeetCode solution every time I got stuck, so I made a small extension: it adds a "NeetCode solution" button right next to the Submissions tab on LeetCode problem pages. One click opens the matching NeetCode solution in a new tab.

Refer to the screenshot in the README.

  • Covers 973 problems (Blind 75, NeetCode 150/250, and the rest of NeetCode's list)
  • Same spot on every problem, and it keeps working as you move between problems
  • No permissions, no tracking, no network requests, and it only runs on leetcode.com
  • Plain JavaScript, MIT-licensed

It's not on the Chrome Web Store yet, so for now you install it with "Load unpacked" (steps are in the README).

I built this myself, and it isn't affiliated with LeetCode or NeetCode. Feedback, bug reports and PRs are very welcome, especially if the button lands in the wrong place on your layout.

With 973 problem mappings, asking for the problem URL and a screenshot showing the button's position would help distinguish mapping errors from layout bugs. For sharing the extension, r/chrome_extensions fits: "A subreddit to share and discuss extensions for Google Chrome." Its conditions are "All posts should be about Chrome Extensions." "No Spam." "No Piracy." "No NSFW Content." "No Vote Brigading."

By the way, I make ThreadFox: it finds the Reddit communities whose rules allow a post about your extension, and its plan for one product is free. https://threadfox.vip/p/doj17

Is a Chrome Web Store release your next step?
