Who should use which
ShareDuo is browser-first with viewer analytics. drop is CLI/agent-native, zero-knowledge, and free on your own domain — better when you don't want client work on a vendor's servers.
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.
Is it zero-knowledge?
Locked drops are AES-256 encrypted in the browser via StatiCrypt before upload. The server stores only ciphertext — never your content or password.
