We've been one of the very early Meteor users, since 2013 (our previous startup is featured on their landing page). After about 10 years of scaling on Meteor & Galaxy, we ended up moving Meteor into our own custom AWS cloud because of lack of observability.

As for the framework, we always wanted to have things like built-in config management, cron jobs, and better live data support (pub/sub was too rigid) - Meteor was actually a huge inspiration in creating Modelence.

The client/server communication in Modelence is somewhat similar to Meteor, for example: https://github.com/modelence/examples/blob/main/ai-chat/src/...

And then the client calls these via react-query useQuery/useMutation for which Modelence has an adapter.
