Vercel Drop is a quick way to put static files online — public, temporary. For private, branded, password-protected sharing from a CLI or agent, the tool 'drop' (this one) is a different shape.
Public demo vs private share

FAQ
Is it really open-source and self-hosted?
Yes — MIT licensed, and it runs on your own Vercel Blob + domain. No third party ever holds your content (it's encrypted client-side) or controls your URL.
