- Does a preview cost extra?
- Previews come with every Vercel plan. Builds use build minutes, which Vercel meters on Pro. Putting previews behind a password is a paid add-on on Pro as of 16 October 2026, while Vercel sign-in protection is included on every plan.
- Can people outside the company see our previews?
- Only if you let them. Previews can require Vercel sign-in, or a password on Pro. We usually keep previews behind sign-in and share a link with the people who approve.
- Does rollback undo database changes?
- No. Instant Rollback switches which deployment serves your domain. Environment variables and anything the old code wrote to a database or Salesforce stay as they are. That is why we write a rollback rule before go-live.
- Do we need GitHub?
- You need the code in Git: GitHub, GitLab, Bitbucket or Azure DevOps. If your site lives somewhere else today, moving it into your own repository is the first step of the build.
- Can preview forms send real leads to Salesforce?
- They should not. We point preview forms at a Salesforce sandbox or tag them as tests, so your sales team never chases a lead that was a developer checking the form.
