Event Sourcing has been around for decades, yet many developers still find it intimidating. Buried under domain-driven jargon, inconsistent examples, or complex frameworks.

That’s exactly why I built eventsourcing.dev. A concise, no-nonsense guide to understanding and implementing event sourcing from first principles.

Why This Exists

Most tutorials mix theory and tooling in confusing ways.

On eventsourcing.dev, the goal is different: to make the concept of event sourcing approachable, explain its core ideas clearly, and show how to use them in any tech stack, without prescribing a framework or product.

What You’ll Find

• Fundamental Concepts: Events, Streams, Aggregates, Snapshots, ... explained in plain language.
• Design Principles: How to structure event-driven systems that scale and stay maintainable.
• Learning Path & Glossary: For those who want to go from curiosity to real-world implementation.
• Resources Section: A curated overview of major event sourcing databases and libraries such as Axon, Kurrent, ...

No Product Pitch - Just Clarity

The site isn’t about promoting any specific tool.

It’s about understanding event sourcing deeply, so you can decide what fits best for your architecture and team.

Anyone can contribute to make the list of libraries and software resources more complete and no one’s excluded, and every genuinely helpful project deserves a place.

The goal is to build a source of knowledge that stays neutral, practical, and open.

Why It Matters

Event Sourcing isn’t just a persistence strategy.

It’s a mindset: designing systems that remember what happened instead of just where they are now.

Once you see data as a timeline instead of a snapshot, consistency, auditability, and traceability stop being problems, they become features.
