Why KurrentDB?
Deliver intelligent applications at scale with a database designed for the modern, event-driven world.
Build Faster
Accelerate product development cycles by 30-50%
Evolve Freely
Iterate and adapt without downtime or costly migrations
See Everything
Understand not just what happened but how and why it led to outcomes
Sync Anything
Deliver the right data to the right place, in real time
Time to rethink the data model
Stop losing context. Move beyond the limitations of traditional state-based databases.
Remember
Loses data with every update and delete
Preserves your complete history
Explain
Can’t tell you how it got to where it is
Gives you the full story — every change, with context
Evolve
Requires time-consuming and risky schema changes
Projects the same source data into any new shape
Roll back
Current state only, unless you build workarounds
Replay, rewind or rebuild to any moment
Prove
Makes you build audit logs as an afterthought
IS the audit log
Communicate
Poll for changes, implement triggers, or bolt on CDC
Streams changes natively in real time
The KurrentDB difference.
Only KurrentDB Delivers
Complete data preservation
Built-in audit and traceability
Replay and time-travel
Data products in any shape
Change without refactoring
Integrated data movement

“Kurrent transformed how we think about our data. We no longer just store state; we store intent.”
Chris Bradford, Engineering Lead, Storied
“The real-time streaming capabilities saved us months of work building custom middleware.”
