BACKEND FOR GAMES THAT NEED TO SHIP
Deploy your game and get a live URL in 60 seconds. Add real-time multiplayer with one SDK. Built for indie devs who want to ship, not manage infrastructure.
Free beta — no credit card needed.
// That's it. That's the whole backend.
import { connect } from '@watchtower-sdk/core'
// Join a multiplayer room
const room = await connect('my-room')
// Send to everyone
room.broadcast({ x: 100, y: 200 })
// React to messages
room.on('message', (from, data) => { ... })
"I spent a week on multiplayer networking and I still don't understand lag compensation"
"Setting up a backend is taking longer than building the actual game"
"I just want players to connect and see each other"
"My game works on localhost. Deploying it is a different nightmare."
"I googled 'simple game backend' and got enterprise solutions"
"I'm mass quitting multiplayer. It's too hard." — actual r/godot post
