I personally like Croc, which is based on Magic Wormhole, but which requires the recipient only to download a single cross-platform executable. They’ve even added a gui, making it easier to exchange files with less technologically sophisticated folk.
Looks good! I’ve added croc under “Worth Mentioning”. Thanks, buddy. Related GitHub discussion: https://github.com/privacytoolsIO/privacytools.io/issues/991
