Why CHose Axoniq

Why store the result, when you can keep track of the entire story?

Traditionally, only banks, large retailers and highly regulated institutions needed to keep track of every change in their systems. This is called event-sourcing. With AI agents running around every production system, this is no longer the case. Everyone needs event sourcing and Axoniq is making it as accessible as your legacy system.

Why Axoniq platform

Axoniq platform lets you build systems that remember,
at entreprise scale

Giving your systems reliable memory must cover the entire product stack. From effective modeling, to your programming stack until deployment and post deployment. Axoniq platform is the only solution that covers the entire stack.

Axoniq framework

The number one event sourcing and CQRS framework. Fifteen years in production and still setting the standard.

Event sourcing by default. Rebuild aggregate state from its own event history, with no ORM mapping to maintain.

CQRS building blocks. Aggregates, command, event, and query handlers wired together with minimal boilerplate.

Workflows. Durable execution for long running, multi step processes across services. The modern successor to sagas.

Spring Boot native. Auto configuration and starters get you productive in minutes on the stack you already run.

Axon server

How the world's leading institutions deploy mission critical, event sourced systems. Event store and message routing in one.

Event store: specialized database for event stores

Message routing: Routes commands, events, and queries between your services, so you do not run a separate broker.

Clustering and high availability: Replicates across nodes for zero downtime and read scaling under production load.

Security and multi-context. Access control, isolated contexts, and audited access, out of the box.

Axoniq intelligence

Start, build, and use your Axoniq systems with an AI layer that understands your events.

Axoniq Discovery: map your domain and events in brownfield projects

Axoniq Dev Agent: build and evolve faster ith spec driven development

Axoniq Insights: natural language and SQL access to your event store
