This is actually a feature missing from many browsers. Maybe Discord has a workaround, not sure.

Movim.eu recently added it, but it only works on Chromium based browsers.

https://f-droid.org/packages/se.lublin.mumla is not so bad as a mobile client for Mumble.

It’s a fork of a fork or Conduit.

Starting point based on what? Do you plan to use it personally to join many large channels from FOSS projects? If so, you need to plan for a relativrly beefy VPS, like 4 core, 8gb ram, 100gb+ ssd storage.

But for small private chats with no federation a cheap minimum VPS can work.

If you want my personal recommendation I would avoid hosting Matrix. A well federated server is costly to run and not really worth the hassle and a small private chat server with bridges etc can be done equally well or better with XMPP.

As others have already alluded to, Matrix is a bit odd in that regard as it runs a distributed database and the resource requirements depend on how much of the matrix network is mirrored on it. A single power-user can cause huge resource use just by connecting to a lot of federated active rooms. On the other hand a server that is mostly used as a private family chat can run on a modern RasberryPI without much problems.

Synapse or Conduwinity etc. makes little difference in praxis as both need to do the same database merging operations.

They removed a lot of cruft and low quality code from Pleroma and in general it is developing at a nice and steady pace. In addition the developers are not right-wing nut jobs.

Akkoma is better. Look for those.

Xmpp has no marketing budget and a lot of people just decided it is old and always share bad experiences with it from 15 years ago 🤷

Well, this is kind of work in progress for XMPP and DeltaChat doesn’t support it. But you can for example try out https://movim.eu/ which is a webbased xmpp client (with PWA app) which does support screensharing in small group calls.

Matrix stans mentally block out the many issues it has, so take everything they say with a grain of salt 😅

These days not so much, but you might find their contracts with the military also objectionable.

But they got a major early investment in 2018 from Status, a cryptocurrency/web3 company, and later in 2021 an even bigger one in relation to Protocol Labs, who peddle their own cryptocurrency.

But personally I would not recommend Stout either as it is not a serious project nor does it federate. Maybe look into XMPP or DeltaChat.

I mean good that you are interested in hosting a proxy, but Nginx Proxy Manager hides away a lot of features and is probably not such a good idea to use when you want to run more complex and security relevant apps like a Signal proxy.

I know this is a bit annoying as an answer, but learning a bit of regular Nginx is probably the better idea in the long run as you usually outgrow NPM quickly.

Fedidb does that for instances, but not individual communities. Might be easy to add though.

No, they rebranded LiveKit, which is open source but afaik developed by a silicon valley startup.

Get the one with the newer SoC. The smaller one is waaay to slow (same as Librem5).

Most microblogging platforms actually don’t artificially limit the amount you can write, unlike Mastodon, so they can also work for macro-blogging.

Maybe overkill, but Peertube can definitely do that well.

Your server might have been hacked. There was a recent issue with a NodeJS software injecting a cryptominer onto other peoples servers, but I forgot the exact details.

ATProto isn’t federated or decentralized in any meaningful way.

What people say about Synapse is also somewhat outdated. These days it isn’t actually that much worse than Conduit (or forks), the main issue is that when you start joining older and bigger rooms the resource use goes through the roof, and that is also a problem with Conduit etc. Ultimately, this is a protocol issue and not an implementation issue.

There are multiple good XMPP mobile apps for Android: https://joinjabber.org/docs/apps/

The story on iOS is somewhat less good right now, but Monal is ok and Movim works quite well as a PWA in Safari.
