Common reasons people leave LeetCode: teaches interview puzzles, not how to build real software, and official solutions and many popular questions sit behind Premium. We ranked 7 alternatives by how directly each one replaces LeetCode, then by reviews, real visits and how recently each app's facts were checked against its own website. GeeksforGeeks currently ranks first.
