FastPubSub Network

Resilient realtime pub/sub over the global Internet

Realtime delivery for API platforms

Add realtime customer connections without exposing every origin server. The mesh keeps customer streams alive when Internet paths between regions degrade.

Built for API businesses that need global reach, origin shielding, stable latency, and backend workers processing realtime traffic in parallel.

What API platforms usually fight

Origin exposure

Realtime clients can force your own servers to hold long-lived connections from every customer, region, and network.

Peaks are expensive to provision

Buying capacity for worst-case traffic leaves infrastructure underused most of the time.

One backend path is fragile

If all realtime traffic is pinned to one ingress or one worker path, failures and slowdowns show up directly in customer experience.

What changes with FastPubSub

Shield the origin

Customer clients connect to edge relays. Your services publish and subscribe behind your own perimeter instead of exposing every realtime connection directly.

Multi-backend active-active

Run multiple backend workers active-active for realtime traffic instead of depending on one central socket server.

Scoped access tokens

Issue scoped tokens for tenants, channels, publish/subscribe rights, and short-lived sessions, so customer apps, workers, and services get only the access they need.

Separate tenants for customers and environments

Keep dev, staging, and production traffic separated with different tenants, tokens, and channel namespaces.

Pay as you go

Launch without sizing a global realtime cluster first; grow capacity with usage.

Enterprise reserved capacity

For guaranteed bandwidth or reserved capacity, contact us and we can allocate dedicated resources on a non-public network for enterprise customers.

Good fits and wrong jobs

Good fits

  • Realtime APIs for customers and partners
  • Origin shielding for long-lived connections
  • Tenant isolation for customers, projects, and environments
  • Scoped tokens for tenants, channels, publish/subscribe rights, and TTL
  • Active-active backend workers consuming live traffic
  • Enterprise reserved capacity for guaranteed bandwidth requirements
  • Global edge access without building your own PoP network

Use another system for

  • Long-term storage and retention
  • Historical replay and analytics pipelines
  • Strict ordered stream processing
  • Large object delivery and caching

FastPubSub is for live delivery. Keep databases, queues, and analytics systems for the durable parts of the platform.
