Vercel & Deploy

Deploy from GitHub, previews, env variables, domains, rollbacks.

Deploy

Deploy a GitHub repo to Vercel for the first time

Your code is on GitHub and you want it live on a *.vercel.app URL that redeploys on every push.

Preview vs production: where does my push go?

You pushed and want to know whether the live site changed, or how to test safely first.

safe beginner

Configure

Add and use environment variables

The site needs an API key, URL or setting that must not live in Git.

Add a custom domain to my Vercel project

You own a domain (like example.com) and want the site served from it instead of *.vercel.app.

Roll back & debug

Roll back a bad deployment

You deployed and the live site is broken. Restore a previous version fast.

careful intermediate

A deployment failed: read the build log

Vercel shows 'Error' or 'Failed' on a deployment, and you need to find out why.
