Do P2P Messaging apps that don't require the internet exist?

Would this work through something like meshtastic?

Telegram isn't P2P and isn't recommended. Signal is good, but not P2P. Matrix is decentralized, not P2P. SimpleX is P2P, I think, but not sure.

Briar or meshtastic

[liamthebox@lemmy.ml]

SimpleX uses onion links

[theroff@aussie.zone]

yggmail specifically, probably not. yggdrasil uses TCP/IP and the Meshtastic latencies to perform connections would be too high AFAIK. It would probably only work in a fairly well-connected network. yggdrasil could be used directly over a WiFi protocol but it would need fairly good reception to function.

N.B. I haven'texperimented with this myself.

Simplex uses Severs, you can bring your own one, but it is not peer to peer when talking about direct communication to the recipient

Honestly if you don't want to think too much about it, go with Briar, it's way more battle tested, while Berty seems like it hasn't seen much adoption since it's younger, both have a bit of development activity I saw, so I can't say if one is more or less maintained than the other

I never used it for messages, but it could send files wirelessly

It’s not p2p but at least many years ago:

SMS.

If the Internet outage is local then the towers would still work and you’d be able to get texts. I went through a few storms where wired home internet was down, the towers weren’t giving me a data connection (no mobile web browsing or anything), but I was able to send and receive texts.

If you really care about what you’re asking after, do what someone else said and get a radio license. It’s 150 year old technology and every time something happens radio operators pop up some kind of emergency communications or bridge to the internet through repeaters or something.

It's not owned by Meta and it's relatively well-known. It's older than Signal.
