If you want something that's more of a Slack/Discord alternative, gajim is receiving a lot of attention and polish lately, with Dino and Beagle as simpler alternatives. Source: over 1 year ago

I used Pidgin back in the day of AIM and ICQ, but nowadays, for XMPP, there’s Dino and Gajim for desktop and Conversations.im for Android. As far as I know, OTR has been superseded or replaced by OMEMO in most clients. Source: over 1 year ago

Https://gajim.org/ is a pretty good one. Source: almost 2 years ago

You can get a number from jmp.chat and use an app like Gajim (available on Windows/Mac/Linux). Source: over 2 years ago

On the desktop I use the gajim XMPP client. On my phones I use Conversations and Blabber (the latter is a fork of Conversations), and all messages between clients are encrypted with OMEMO. Source: over 2 years ago

For file transfers over the internet, https://wormhole.app/ and https://toffeeshare.com/ are often suggested. - Source: Hacker News / 3 months ago

Isn’t https://wormhole.app/ the solution here? Note I haven’t used it, it’s just often brought up here as a good solution for this class of problem. Is it surprising that the author mentions a ton of solutions but not this one? - Source: Hacker News / 4 months ago

One of the two creators of https://wormhole.app here :) Now that we’ve shifted our company’s focus to https://socket.dev, I’d love to open source Wormhole. I’m quite proud of the code - I’ve worked on P2P and file transfer systems for so so long that I think this might be some of the best code I’ve worked on. It’s just a matter of finding the time, but I expect this will be open source eventually. - Source: Hacker News / 5 months ago

It's unfortunately not FOSS, but I quite like https://wormhole.app/ - It's client side encrypted and P2P when possible. - Source: Hacker News / 5 months ago
