Why deploy on Railyard

Railyard runs it standalone on a server you already pay for — no addons to provision, with zero-downtime deploys and scaling still included.

Deploying Centrifugo is one piece of a bigger stack you can keep building — add a database, a worker, a cache, or another app, all on the same servers you already pay for.

Good for

Real-time features (chat, live updates, notifications) for a web or mobile app
A language-agnostic pub/sub layer in front of your own backend, over WebSocket/SSE/HTTP-streaming
Presence and online-status tracking across many concurrent connections

Good to know

Runs with the in-memory engine — presence/history don't survive a restart; point ENGINE_TYPE/BROKER at Redis after deploy if you need that to persist or to scale beyond one instance
The admin web UI is enabled and served on the same port as client connections
