Suggest me a secure chat platform for my family

I've been using matrix for years to this purpose, but moving to xmpp/prosody now

Any Reason Signal doesn't do it?

Selfhosted isn't always the Best option

Edible paper, lemon juice, and hair dryers.

three main ones I've seen in this comment section are

• XMPP

• Matrix

• SimpleX

XMPP. It just works, requires very little resources, is stable and has decent clients.

I would go with Snikket instead of Prosody if I had been starting now.

Conversations on phones, Dino or Gajim on PCs, plus a conversejs install on the xmpp server, to allow web access when needed.

Conversations is easy for the family to figure out.

https://snikket.org/ (xmpp based) is perfect for that. Matrix will work, but you will likely reach the limits of your Raspi with it fairly soon if you allow federation with other servers.

E2E is complicated, if you self-host for a group, having TLS and encrypting data at rest (storage) may be enough. Get a threat model. That being said, I would recommend snikket.org which is a superset of extensions over XMPP which is the open source IM that was the base of almost every app out there. Matrix and Rocket are both alright too. Depends too on your resources, synapse requires too much RAM (or so I heard)

Ideally, SimpleX (https://simplex.chat/). Session is nice, but less secure (https://getsession.org/). Delta Chat (https://delta.chat/en/) will be secure enough, and the most familiar visually. Lastly, XMPP is a great solution as well.

I know it's not self hosted but why not Signal? Matrix is demanding on a SBC and your family would probably get the 'unable to decrypt message, please re-verify keys' error that happens in encrypted matrix group chats and Element does not have the best UI especially if you want your grandma to use it.

Matrix or XMPP.

Still no suggestion that has wide cross platform and it’s just simple . Matrix has that all . So for now I choose matrix and clients

I just have my kids, wife, close friends and in-laws on SimpleX.

Sure, some of them use mainstream stuff as well, but if they want to reach me, that's their only option.

Matrix is a pretty good choice for self-hosted. The reason I don't do it is because I've become lazy lately.

I recommend Matrix with the Conduit server. This server requires almost no resources and even runs on a Raspberry Pi.

Cinny works perfectly as a desktop client (in case you want to escape from the ubiquitous Element). And for mobile I would use Element for Android/iOS although FluffyChat also works very well.

For me you can try to host a SimpleX server and then connect to it (with SimpleX it is pretty as much secure to run its one server than use a public one).

Or maybe use XMPP but try to use a good encryption protocol. This option is great in term of power efficiency, XMPP would run great on a RasPI

matrix should cover everything you need with the added bonus that you can chat with people from other instances

You could try Jami. It's peer to peer, so essentially any participants are self-hosting it. Its E2E encrypted, supports group messaging, voice and video calling, has easily 'linkable' mobile and desktop apps for all platforms and requires no email address or phone number to use. It's also the only messenger I'm aware of which is endorsed by the Free Software Foundation. I highly recommend it 👌

Matrix is good, secure, very versatile, Foss, and easy to use, but I think not easy to set up or manage.

The other suggestions are probably better, but you can technically self-host Wire (from Wire Gmbh) but I've never done it successfully.

Simplex chat would work

However, I wouldn't host on a Raspberry Pi or even at home for that matter. Get a VPS and host it there. Linode even has a one click app install for Simplex Chat

Mattermost runs as a Docker container and is excellent. You can create channels and groups which is incredibly useful.

Rocket chat is like slack but FOSS.. haven't tried it myself but it could be something

XMPP is fantastic IMHO

If you want to support a great project and have great uptime check out conversations.im

I don’t recommend self hosting something you want available all the time. That being said everyone has different needs/uses 😊

Once upon a time someone did a write up on hosting your own signal server, idk if that’s super overkill but google ought to find that.

Zulip hit's the sweet spot for me, as it's pretty straight forward to use and not too many bangs and whistle's.

Alternatively I'm also very happy with signal for communicating with other ones where Idon't have to vother about user management too much.

Self host beeper... I love matrix but people struggle with maintaining a key and password .. beeper simplifies this and has other chat protocols (bridges) that might entice normies.

also: that has a client that works on android tv.
