You built an app with AI. Now it has to run somewhere.

You described what you wanted, an assistant wrote it, and after some back and forth it works. You can see it at localhost:3000. It does the thing.

Then you try to show someone, and there is nowhere to send them.

If you have spent the last few days getting increasingly frustrated at this stage, here is the useful thing to know first: you have not hit the limits of your ability. You have hit a different job.

Building and deploying are genuinely separate skills

Writing the app is about behaviour — what happens when someone clicks the button. Deploying it is about everything the code assumes and never says out loud: that a database is running, that the machine has the right runtime, that something is listening on the right port, that certificates exist, that it starts again after a reboot.
