About LeetArena
STOP GRINDING ALONE. START WINNING. 🏆
Coding interviews are hard. Doing them alone in a dark room is harder.
Arena for LeetCode turns your solitary grind into a high-stakes multiplayer battle.
We don't just track your stats; we visualize the gap between you and your friends so you can close it.
⚔️ THE RIVALRY SYSTEM
Pick your "Nemesis" from your friend list. A massive, dynamic health bar stays pinned to the top of your extension, showing exactly how many solves you are ahead (or behind).
> Red Bar = You are losing.
> Blue Bar = You are winning.
Seeing that red bar is the ultimate motivation to solve "just one more."
🕵️♂️ LIVE SPY MODE
Hover over any friend to unlock "Spy Intel."
- See their "Last Active" timestamp.
- Did they just secretly solve a Hard DP problem at 2 AM? You'll know.
- No more friends claiming "I haven't studied" when they actually have.
📊 GOD-TIER VISUALS
Stop staring at plain text numbers.
- Beautiful, animated "Donut Charts" for every user.
- A premium "Hero Card" for your own profile.
- UI that looks better than the actual LeetCode site.
