flatnotes VS Mumble

https://github.com/dullage/flatnotes , I find it handy

I'm not opposed to this idea but there's a bit of a stumbling block to get past. See the related issue on GitHub for more details (and give it a thumbs up so I can gauge interest).

Try flatnotes for the markdown editor. Simple but functional design, and works smoothly for me

Also note that v2 (with a tagging feature) is coming very soon. You can see the release notes for the release candidate here.

Not as yet but I do like the idea. There's an existing suggestion issue along this line.

bash git clone https://github.com/Dullage/flatnotes.git cd flatnotes docker build -t dullage/flatnotes:latest . docker run --rm \ -e "FLATNOTES_USERNAME=user" \ -e "FLATNOTES_PASSWORD=changeMe!" \ -e "FLATNOTES_SECRET_KEY=aLongRandomSeriesOfCharacters" \ -p "80:80" \ dullage/flatnotes:latest Note: As no Docker volumes are mapped in the run command, notes will not be saved when the container is stopped.

I think Sonobus is overkill. I suggest you look at a couple of relatively old-school gamer voice chat tools - Mumble or Teamspeak. Mumble is open-source and the connection is always encrypted, Teamspeak is commercial but the free tier should be fine for you - but you have to make sure to manually turn encryption on yourself. It has been a long time since I used either, so I don't know which is easier. Both of them require you to run their matching server software.

Mumble's latency is unbeatable imo, it's basically their main focus and shows.

The sticking point for me is the lack of persistent messages, something the devs strangely think is a privacy plus. Issue open since 2016: https://github.com/mumble-voip/mumble/issues/2560

If you drop out for a minute you won't have access to anything that was posted in chat, which makes it useless for anything other than voice only comms, that might suit some business purposes but I've always needed to post links or screenshots in chat during meetings.

There's any number of alternative chat applications available, like Element, Mumble, Teamspeak etc.

Mumble?

I think Mumble might fit what you're looking for. It's been a very long time since I've used it, but it seems to still exist: https://www.mumble.info/ - I've used previously for exactly what you're describing, events with lots of crew dispersed around and no budget for radios. I had it installed on an AP running OpenWRT so it was just a case of plugging that in and getting people to install the app and connect to it.

Along with the options already mentioned, if you're not into TeamSpeak, there is an open source alternative called Mumble which operates in the same manner. No internet required, and is supported on multiple platforms.
