Hey!

I'm Patric, and I just hit a major milestone - Genesis DB 1.0.(1) is officially production-ready.

Why I built this: Existing event sourcing tools felt too heavy, opinionated, or expensive. I wanted something that matches how developers actually think about events - simple, transparent, and powerful.

What Genesis DB is:

- Event sourcing database engine written in Go

- HTTP + JSON interface (no proprietary protocols)

- CloudEvents native with zero vendor lock-in

- One-command backups/restores

- Built-in Prometheus metrics & structured logging

Major features that made it to 1.0:

- Smart validation - Preconditions act as gatekeepers, enforcing business logic before writes hit the database

- Schema registration - Automatic event validation for type safety and data consistency

- Native GDPR compliance - One-command user data deletion, full data portability, built-in audit trails

- Battle-tested performance - Thousands of events/second, zero data loss, stable under load

- ...

The journey:

- Started because I love event-driven architectures but hated the tooling complexity

- A few versions, each adding features

- Now processing real production workloads across multiple industries

Want to try it? - Free tier: 10,000 events for testing/small projects (I’m not here to be the biggest cost factor in any business. If you’ve got special requirements, let’s talk.)

- Self-host or use the managed platform (coming soon)
