Ship a multiplayer game this weekend.
You write gameplay — we ship everything else.

Identity, friends, leaderboards, real-time PvP rooms, in-game shop and distribution — all included with a 9-method SDK. One HTML file is a complete game.

Start building What is HOOP?
Included
Everything around your game, prebuilt

🎭 Identity & privacy

Players arrive with a per-game shadow ID, name and avatar. You never touch real accounts — privacy is enforced by the platform, not by your diligence.

⚔️ Multiplayer rooms

Create, invite, turns, reconnection, disconnect walkovers, mutually-attested results — a full PvP backbone via 9 SDK calls. The platform relays; your payloads stay yours.

🏆 Friends & leaderboards

Friends-circle and global boards, rendered-ready entries with ranks and avatars. Social distribution built in: invites land in real chats.

📱 Real-device testing

Others hand you a simulator. HOOP runs your draft on a real phone with the full production bridge — real friends, real rooms, real shop — before you ship.

🛒 Shop (soon: revenue share)

Sell game items through the platform wallet. Revenue sharing for developers is on the roadmap.

🚀 Instant updates

Your game is a hosted H5 page. Push an update, players get it on next open — no app-store review, no reinstall.

Start
Zero to multiplayer in five steps
  1. Copy the template. template-race21/ implements the whole integration guide with section-by-section annotations.
  2. Develop in your browser. One script tag gives you a mock platform: fake identity, friends, boards, and a bot opponent.
  3. Apply in the HOOP app. Settings → Developer Center → claim your game id.
  4. Test on a real phone. Point the Developer Center at your machine's IP — your draft runs with the full production bridge.
  5. Submit. One review, then your game is live in the Game Center for every HOOP user.
