Managed event sourcing
that scales with you.
Append events to immutable logs, deploy WebAssembly views to process them into materialized state, and query results instantly. No infrastructure to manage.
How it works
Three simple operations power event-driven applications
Append events
Send events to immutable logs. Events are ordered, never modified, and never deleted.
Deploy views
Upload WebAssembly views that process events into materialized state like totals, aggregates, or projections.
Query instantly
Query view results in milliseconds. Strong consistency ensures you always see the latest state.
Why engineers choose Primatomic
Ship faster
No Kafka maintenance, no Kubernetes clusters, no operational complexity. Just append events and query state.
Data you can trust
Immutable logs with full history. Automatic snapshots. S3-backed archives. Node failures don't lose data.
Scale without worry
Usage-based pricing. Pay for storage and compute only. No minimums, no surprises.
Perfect for
E-commerce platforms
Track orders, inventory, and customer history. Rebuild state from events for audit trails and analytics.
Financial applications
Maintain immutable transaction logs. Compute balances and positions through materialized views.
IoT and telemetry
Ingest sensor data streams. Create views for real-time dashboards and anomaly detection.
SaaS analytics
Capture user events. Materialize usage metrics for billing and product insights.
Primatomic vs. alternatives
| Primatomic | Kafka + custom | Database-triggered | |
|---|---|---|---|
| Infrastructure to manage | None | Kafka cluster, Zookeeper, consumers | Your database |
| Event replay from history | Built-in | Manual setup required | Not available |
| Snapshot & restore | Automatic | Manual implementation | Not available |
| Compute isolation (WASM) | Sandboxed | Shared process | Same as app code |
| Pricing | Usage-based | Infrastructure cost + engineering | Database cost + complexity |
Built for durability
Three layers of persistence ensure your data is always safe
S3 Archives
Every event persists to S3 independently. Replay from any point in history, even after stream retention expires.
Automatic Snapshots
View state checkpoints to S3 at configurable intervals. Fast recovery without replaying entire event history.
Automatic Failover
Cluster coordination ensures exactly-once processing. When a node fails, another picks up seamlessly.
