Unfortunately the solution presented in the article is locked to a closed cloud offering. I have nothing against those, Firebase for example is like that, but I dislike the fact that it’s hidden. “It’s just an sqlite extension”, oh and it syncs with our commercial cloud offering only.

Other vendors like Powersync and ElectricSQL have a similar offering but are upfront about it. And at least in Powersync’s case (don’t know about Electricsql) you can also run their offering yourself.
