Came out in march. Easy to install on a $5 droplet or a VPS.

Dropbox and wetransfer/send don't serve the same needs and don't offer the same experience.

I could see Dropbox getting back into the office with that tool, they have a brand to capitalize on after all, if they drop the mandatory login.

? elaborate plz. you don't need a droplet to use ff send

I self host a ff send instance. See https://github.com/mozilla/send
