Where Netlify Drop is the better pick
Netlify Drop is fantastic for exactly what it’s for: instantly previewing a build, sharing a quick demo with a teammate, or kicking the tyres on a static site before you wire up a real Netlify project with Git, CI, and deploy previews. If you live in that pipeline, stay there. SiteViewer is the better fit when the link leaves your team and lands in front of a client, where it needs to stay live, stay private, and look like your studio rather than a random deploy URL.
