Hi HN! I created reaktiv, a Python library that brings reactive Signals to the backend world.

The frontend ecosystem has already embraced Signal-based reactivity (Angular, SolidJS, React) with tremendous success. It's time for Python developers to enjoy these same benefits. My breakthrough came when I stopped describing it as "Angular signals for Python" and started calling it "Excel-like computation graphs" - suddenly Python developers understood the value.

reaktiv automatically tracks dependencies between computations, only recalculating values when dependencies change. This eliminates manual dependency tracking, prevents synchronization bugs, and reduces cognitive load when managing complex state - benefits that are just as valuable on the backend as they are in UI frameworks.

I'm seeing initial interest from data scientists and believe the Home Assistant/IoT communities could benefit greatly from this approach. Python deserves the same modern reactivity patterns that have revolutionized frontend development.

Would love your thoughts on bringing Signals to the Python ecosystem!
