The event infrastructure layer your app is missing.
Primatomic is an append-only event store with programmable views. You tell us what happened. We keep it forever and let you query it however you want.

Learn more →How it works
Four steps to production.
Create a log
An immutable, ordered sequence of events.
Append events
Raw bytes. JSON, Protobuf, anything. Never modified, never deleted.
Deploy a view
A WebAssembly function that processes events into materialized state.
Query state
Millisecond reads. Read-after-write consistency. Always up to date.
