Bring your team into the same project to design, review, and collaborate directly on the website.
Send a shared link. Your site opens with your edits on it and they can walk around as though the design were live. No account, no extension, nothing to install.
From half an hour to a day at one press, or a span you set yourself. Two hours by default. You can keep it to named email addresses instead of anyone holding the URL, and delete it whenever you want.
A shared link with Live turned on. Whoever opens it watches you work on the real site: your cursor, your clicks, your edits as they commit, the pages you open. Chat, microphone and camera are in the bar. Nothing is recorded. See Live.
Yes. A viewer follows your viewport by default and can stop following at any point, keeping their own scroll and their own page while still seeing your cursor and your edits.
A project has an owner and any number of members, invited by email address. Nobody accepts anything, the project is simply there next time they sign in. Roles run from viewer to editor, and a manager runs the work and the agent keys without ever touching the page. See Teams.
No. Teams cost nothing to form, and everyone joins with the permissions of their own plan. A role you grant is capped by that person's plan, so a Free account invited as an editor works as a viewer until it upgrades. On the project you own you always have everything.
