Vercel did a great job with NextJS and supports quite some OS projects.

But even before AI they had some serious struggles according to long time users.

With the introduction of the deployment platform NextJS appeared to be having advantages being deployed there.

What I can say is that Next has some weird things going on under the hood most senior coders know as “it works, no one knows why, don’t touch these 1.000 LoC here”

Build and runtime settings are a mess. Pre building a docker image on a local machine and deploying it on another turned out to be its Achilles Heel. Weird settings prioritize not as documented, different settings in one area lead to changes in default settings somewhere else. ReactJS server components played a role.

In other words: I sense that while being incredibly useful there might more to come.

It ain’t easy for them, V16 was a rewrite which was API stable. I am not sure about that.
