Judgement

What it is

Developer tool

What it does

A command-line client for Send servers that uploads files with client-side encryption and returns an expiring download link.

Adopt it when

You want to share files up to about 1 GB from a terminal through an encrypted link that expires after a set number of downloads or time.

Watch out

Mozilla shut down Firefox Send, so it depends on community or self-hosted Send instances, and the default host is run by the author.
