Everything your stack needs
Designed for teams who need reliable real-time infrastructure without the operational overhead.
Sub-ms delivery
Events reach subscribers in under 0.4ms at p99. Our global anycast network routes around failures automatically.
Type-safe SDKs
First-class TypeScript, Go, Python, Rust, Java, Ruby, PHP, and .NET. Full IDE completion for event schemas.
End-to-end TLS
Every byte encrypted in transit. Mutual TLS available. SOC 2 Type II certified, GDPR-compliant data residency.
Durable replay
72-hour event history on all plans. Replay any window to recover missed events or backfill new consumers.
Schema registry
Enforce contracts between producers and consumers. Backward and forward compatibility checks on every publish.
Live metrics
Per-stream throughput, latency percentiles, and consumer lag. Prometheus-compatible export. PagerDuty alerts.
One API. Every pattern.
HTTP/2 server-sent events, WebSocket, and long-polling — all behind the same endpoint. Switch transports without changing your client code.
# Publish a single event curl -X POST https://api.flastone.com/api/stream/publish \ -H "Authorization: Bearer $FLASTONE_KEY" \ -H "Content-Type: application/json" \ -d '{ "stream": "orders", "payload": { "id": "ord_9x2k", "amount": 4200 } }' # Response { "event_id": "evt_01hxyz", "delivered": 12, "latency_ms": 0.3 }
