Can I open-source LeetCode?
NOT REALLY · nothing credible yetNo credible open-source replacement for LeetCode yet — Reactive Resume are the closest escape hatches, but they don't cross the moat. Because thirty-five dollars for the month before an onsite is trivially cheap against the salary delta, and because nobody wants to author their own curriculum while also preparing for interviews. Premium buys company-filtered lists and editorials, which is a shortcut through the one resource candidates are actually short on: time. A self-hosted drill app competes on none of that. It competes on being a nicer place to redo problems you already understand, which is a real but much smaller need.

How much does LeetCode cost?
LeetCode costs about $35/month (Premium, checked 2026-08-16), which is $420 per year.
What do I lose by replacing LeetCode?
Honestly: The problem bank itself, thousands of problems with hidden tests tuned to catch the specific ways people get it wrong; Company tags and frequency data, which is the main reason people pay for Premium; Editorials and the discussion threads where the actual learning happens; Contests, ratings, and the mild public humiliation that makes you keep showing up; Any signal that you are practicing the same questions your interviewer will ask. If any of those are load-bearing for you, keep paying.
