Deployment behaviour on Vercel

Question

When pushing to main branch, vercel automatically creates a deployment with a random subdomain.

Is it possible to disable this behaviour and only push to production, to a specific domain? What about the preview deployments?

Answer 1

TLDR: All deploys have unique URLs. But also there's a single production URL.

You can have simultaneous versions (each with unique subdomain) but when a deploy is successful, it automatically updates the production URL.

For example:

1. You make your first deploy
2. Vercel provides you this link, with a random subdomain: project-random001.vercel.app
3. Vercel ALSO provides a clean production URL for the SAME page: project.vercel.app
4. You make a second deploy
5. Vercel provides you yet another link, with a random subdomain: project-randomsub002.vercel.
6. Vercel updates environment, keeping the same url (project.vercel.app).

So your production URL has always the newest version, while each deploy has unique URLs.
