Playroom

Playroom, the multiplayer backend formerly known as Booom.ai, exists to remove the hardest part of shipping anything real-time: the server. Instead of standing up, securing and scaling your own networking infrastructure, you plug in an SDK and let Playroom manage rooms, presence and state synchronisation. Developers describe the result as multiplayer without the backend work, which is why the platform is popular with small web game teams and indie studios.

The product targets both games and collaborative web apps. On the game side it supports cooperative and competitive play where every player sees the same shared state at low latency. On the app side the same primitives power shared whiteboards, live cursors, multiplayer editors and other synced experiences. SDKs are provided for popular web frameworks such as React, Next.js, Vue and Angular, and for engines and 3D libraries including Unity, Godot, Three.js and PlayCanvas.

Pricing follows a freemium model, with a free tier to prototype and paid or enterprise plans as usage grows. The classic benefit is speed: a team can add a real-time layer to a prototype in an afternoon rather than spending weeks on websockets, reconnection logic and authoritative state. Teams that need more control can still reason about the architecture because Playroom exposes rooms and state explicitly rather than hiding them behind opaque magic.
