A code diff does not show an editor whether a long headline breaks the page. A preview deployment gives that discussion a working URL. Netlify’s existing Deploy Previews workflow builds a separate version of a site from a pull or merge request in a connected repository.
The preview is distinct from the production site. Successful subsequent builds update the pull request’s preview URL, and Netlify also exposes a deployment-specific permalink. The documentation explains that distinction and the repository configuration involved. This is a workflow explainer, not a newly announced feature.
Review a page with real content
For a software publication, a useful preview check includes a long title, a tall product logo, an article without an optional field, and a narrow screen. Those cases are easier to discuss when everyone can open the same build.
The team should also agree which version a comment refers to. A stable pull-request URL may show newer changes by the time someone returns to it; a permalink can preserve the exact build under discussion. That small distinction helps avoid feedback that sounds contradictory simply because two people were looking at different versions.
