I built an Event-Sourcing Database Engine, because I love Event-Driven Architectures: Meet Genesis DB
What It's Not: It's not trying to be Kafka, Postgres, or a replacement for existing battle-tested systems. But maybe that's a good thing - maybe that's exactly what makes it interesting. This is the first public release, and while it's still growing, it already covers the core features you'd expect from a serious event store. It's not trying to lock you into anything.
Why I Built It: Because I love building systems this way - and I wanted a tool that matches how I think about events, not the other way around.
You might love it. You might hate it. You might even start using it in your own stack.
