Where should I deploy an AI-built web app?

Pick the platform with first-class support for your framework and per-branch preview URLs. Previews are what let you review an agent's change as a running site instead of as a diff.

What to look for

  • 01Does every branch get its own URL automatically? This is the highest-leverage feature for agent-assisted work.
  • 02Is the runtime a real one, or a constrained edge environment your dependencies will not run in?
  • 03What does traffic cost at ten times current volume? Pricing cliffs are the usual unpleasant surprise.

Common questions

Why do preview deployments matter so much with coding agents?
Because they turn review into looking at the working thing. Reading a diff tells you what changed; opening the branch URL tells you whether it works.
Is serverless the right default?
For request-driven web apps, usually — you skip capacity planning entirely. Long-running work, websockets, and heavy background jobs still fit a persistent server better.
