Real-time messaging over measured low-latency paths
Keep multiplayer state updates fast when direct Internet routes are unstable. Cross-region session coordination over measured low-latency paths.
FastPubSub is a managed global service broker for live multiplayer messaging. Deploy globally across the planet or restrict traffic to a single region when you need regional operation.
Multiplayer loops break down when jitter grows or path quality changes. A few unstable paths can affect many players in the same session.
When players connect from different ISPs, mobile networks, and regions, direct Internet routes can become inconsistent over time.
For fast game coordination, live delivery matters more than persistence and replay.
Relays measure RTT, jitter, and loss, then route around bad hops to keep message timing stable.
Game services and clients can integrate through WebSocket today while the relay backbone runs over QUIC.
Messages are distributed near players, reducing central bottlenecks for live multiplayer updates.
Shared state updates for active sessions.
Server-side events to all players in a match.
Player signals to coordination services.
