    • Well, in PostHog (I'm a colleague of Twixes), we just decided here [] to go with Kea, as I had more experience with it.

    Had Redux Toolkit been around when I started with Redux in 2016, I probably wouldn't have needed to write Kea. However I'm glad I did, as I now do consider Kea to be the better toolkit for the same job. :D. I know you disagree, and that's all fine of course :).

    In my mind Kea fills in all the missing parts from React, while Redux Toolkit is still a set of utility functions for state management. You still need to find another set of tools for data loading (I see this has improved), complex data or form management, app routing, scene handling, etc. Redux Toolkit doesn't bother with most of that, and I don't think it should.

    Kea however comes with solutions for all of those. The only thing missing from being able to build a complete app is a JS module bundler. Just sit down and start writing your actual app with the least amount of syntax possible to explain things in a redux'y way. Many people have told me that with Kea, the framework basically gets out of the way and disappears.

    Now with the Kea 3.0 Logic Builder syntax, Kea is suddenly like lego for state management. I'm curious to see if this picks up or not. I can't unfortunately link Kea from redux.js.org to drive traffic :).
