Preview Deployments

4. Preview Deployments

One of Vercel's most powerful differentiators. Every pull request gets a live, deployed version of the application.

Why it matters for enterprise sales

  1. Design reviews: Designers and PMs can click through the actual feature, not a prototype
  2. QA: Testers can verify against the real deployment before merge
  3. Client approvals: Agency customers can show clients a live preview
  4. Catch bugs before production: Each PR is a full deployment with real infrastructure

How to demo it

# Create a branch
git checkout -b feature/new-checkout

# Make a change
echo "Adding new checkout flow..."

# Push — Vercel automatically creates:
# https://my-app-git-feature-new-checkout-my-org.vercel.app
git push origin feature/new-checkout

Integration with Git providers

Vercel comments on GitHub/GitLab/Bitbucket PRs with:

  • Preview URL
