XRSPSOSRS in the Browser

Build gamemodes. Write extrascripts. Run your own server.

🧩

Gamemode System

Extend VanillaGamemode to build your own server experience — custom XP rates, drop tables, tutorials, UI, and progression. Override what you need, inherit what you don't.

🔌

Extrascripts

Drop-in content modules that work on any server. Debug tools, admin commands, custom content — just export a register function and it loads automatically.

🛠️

TypeScript End to End

Client and server both written in TypeScript. Shared cache, shared types, shared networking protocol.

🎮

Browser-Native Client

Full OSRS client running in the browser with WebGL rendering. No downloads, no Java — connect and play.
