Low-latency pub/sub over the global Internet
Start from the product you are building: multiplayer sessions, realtime APIs, or an API platform that needs global delivery without exposing every backend connection directly.
State updates, player events, rooms, and session coordination where jitter is visible to users.
Turn backend events into realtime API updates for dashboards, SaaS products, market data, and customer-facing feeds.
Give customers low-latency realtime access while shielding origin services and spreading load across parallel backend workers.
Relays measure RTT, jitter, and loss continuously, then move traffic away from degraded Internet paths when a better route is available.
Clients connect to FastPubSub edge relays. Your application servers can stay behind your own perimeter instead of exposing every realtime connection directly.
A mesh of PoPs gives users a nearby entry point and keeps routing available even when one region, carrier, or relay path has problems.
Publish once and let the relay fabric replicate near listeners, instead of making your server send the same update to every subscriber one by one.
Use channels for one-to-one, one-to-many, and many-to-many traffic: player sessions, rooms, dashboards, collaboration, or live control flows.
Issue scoped tokens for tenants, channels, publish/subscribe rights, and short-lived sessions, so each client only gets the access it needs.
Separate customers, rooms, projects, and environments into their own tenants, with independent channel namespaces and access rules for publish and subscribe traffic.
Run multiple backend workers active-active for realtime traffic instead of depending on one central socket server.
Launch without sizing a global realtime cluster first; grow capacity with usage. For guaranteed bandwidth or reserved capacity, contact us for enterprise allocation on dedicated resources on a non-public network.
FastPubSub is a managed live-delivery service. Kafka, NATS, and RabbitMQ are usually software stacks you operate for durable streams, queues, or brokered workflows.
