DeltaBase Documentation
The serverless event store for TypeScript developers
Why DeltaBase?
Section titled “Why DeltaBase?”Traditional databases lose history. Update a record, the old value is gone. Delete something, it’s deleted forever. When something breaks, you’re left guessing.
DeltaBase keeps every change as an immutable event. Perfect audit trails. Time-travel debugging. Systems that don’t lose data.
Built on Cloudflare’s edge. TypeScript-native. Zero infrastructure to manage. Pay per event, not per server.
