You know that @chmal.it is cooking 🧑🍳 with Rozenite. He's in Prague tomorrow doing a deep dive into React Native DevTools.
Ever wondered how they actually work? He reverse-engineered the whole thing and built a plugin framework around it.

You know it's a good rewrite coming up! AI space is pretty interesting.
Everyone's building AI agents and AI agent frameworks right now. So many different approaches. Everything changes each week.
Decided to focus on building some production workflows, hopefully this is the last one 😂

Meet Fabrice AI - functional framework for building AI agents.
While building Cali, I needed something stateless that can work on the server, inside CLI, breakdown complex tasks, and be simple.
Couldn't find one, so I built one. Give it a try!
