Module 03
What Is Preview?
Preview is your safe rehearsal. Vercel can create a separate deployed version of your app so you can see, test, and approve changes before they become live.
- Open a unique Preview URL
- Test features and workflows
- Check data behavior
- Test integrations
- Gather feedback
- Fix issues and create a new Preview
- Approve only when ready
Preview may look like your live app, but it is not Production.
