Deploy is the publishing area for turning the current project into a public URL other people can open.
Open Deploy when the project is ready.
The deploy panel shows the publishing state and the public URL. If the project is not live yet, publish it. If it is already live, publish again after major edits so the public page stays current.
Open the public URL before you share it. The live page is what other people see, so check it separately from the workspace preview.
Preview URLs expire after 30 minutes. They are useful for quick internal checks, but they are not reliable for sharing with customers, teammates, or anyone who may open the link later.
Share the published URL, not:
Allow showcase & Remix controls whether the project is easier for others to discover and reuse. Leave it off for private, incomplete, or client-specific work. Turn it on when the project is meant to be shown as an example.
Editing a project does not always mean the public URL has the latest version. After important changes, return to Deploy, publish, and re-open the public page.
