Vercel FAQ

Question 1

Do I need a Pro plan to use preview deployments?

Accepted Answer

No. Preview deployments are available on every plan, including Hobby. Some advanced controls (preview-url passwords, deployment protection) require a Pro or Enterprise plan.

Question 2

What runtimes are supported for Next.js routes?

Accepted Answer

Next.js routes can run on the Node.js runtime or the Edge Runtime. App Router lets you opt in per-route via the runtime export. The Edge Runtime is faster to start but supports a subset of Node APIs.

Question 3

How do I roll back a bad deployment?

Accepted Answer

Open the deployment in your dashboard and click Promote to production on a previous successful build. The promotion is instant and atomic — no rebuild required.

Question 4

Can I bring my own domain?

Accepted Answer

Yes. Add the domain in your project's Settings → Domains , then update DNS at your registrar. Vercel issues a free TLS certificate via Let's Encrypt within minutes of the DNS check passing.
