Using Next.js for self hosting is a really bad idea in my opinion (and experience). Despite of what they say (for obvious marketing reasons) their framework is optimized and developed to run on their platform later.

One of the problems people don’t seem to realize, is that when you use it on your own server you are still “paying” for the trade offs they made. Like you will run into artificial limitations that should not be there at all, except because those limitations only help keeping the door open so that you can move into their platform. If they removed those limitations then moving into their platform would be a lot more difficult and obviously they don’t want that.

Do you want proof of that?

Check that whole conversation. It’s now closed with some bullshit because they don’t like people realizing this.

So… if you are using Vercel, then great. Next is your best option for their platform. But using Next outside of vercel is a terrible idea. There are far better options for that.
