Still a bit alpha, but looks promising. Several features seem to be waiting for atproto implementation.

I wonder how much of it is vibe coded and when will it lose updates after being released…

ATProtocol where you host the data but have no control of it.

Is matrix too difficult to develop or contribute to? Why do new chat apps keep popping up that do the same?

I haven't tried it, but seems to be difficult enough that practically everyone uses the SDK. And also, before the SDK existed, practically nobody was successful in doing it.

I'm not a developer, so I don't know the actual effort involves, but it seems to me like making a new one is like reinventing the wheel. Matrix probably has solved many problems that this new things still has to run into.

What's an SDK? I looked it up but can't really understand the techno lingo on wikipedia. It's a "kit" (whatever that means) that allows developing a platform specific app? Matrix isn't another OS like Linux, so I'm confused.

Not a fan of chat rooms but nice not being an informational blackhole for once.

I wonder how's compatibility with Wafrn and people who follow @bsky.brid.gy@bsky.brid.gy though...

You do have control over it though, I don't get what you're saying

https://github.com/matrix-org/matrix-rust-sdk

SDK is a library layer that hides the complexity of a thing inside an easier facade. It's exactly the right thing to do when the thing is a complicated one, but it also hints towards ... you know, the thing being complicated.

We haven't quite figured out whether a chat network needs to be as complicated as Matrix is under the hood. Could be that it does: federation, E2EE and the overall design of Matrix (it being a log propagator instead of a more traditional message passing system) increase the technical challenge by a lot, but then again, none of the three are essential (although undeniably useful in certain cases) for a chat network.

The hardest bit is encryption, you can get a basic app or bot running trivially from scratch if you don't care about that. People successfully wrote matrix apps for years before the Rust SDK existed, and there are plenty of other bits of the matrix ecosystem that don't use it (mautrix/Beeper is mostly written in go!). The Rust SDK is nice to use and give a bunch of bonus features on top, so that's why it's popular.

HEY HEY HEY, don’t get me wrong now but I’m seeing dozens of Discord-like apps over the past year and can’t understand one thing about them, which is WE ALREADY HAVE THE CHAT PART SINCE FUCKING 1988, it’s called IRC, it’s lightweight, not bloated, works everywhere, extendible and still maintained.

Discord (and Slack) are proprietary IRC forks themselves and adds almost NOTHING to that equation.

It’s the voice/video call part that Discord solved an none of these forks attempting to tackle that part.

AT Proto is a terrible base for a chat app. There's a reason Bluesky's DMs aren't stored in your PDS. Hell, even your bookmarks (which are stored in your PDS) are off protocol.

It has a single committer and there are two commits with Claude as co-author, so I would suggest it's probably about as you'd expect.

Colibri to my knowledge is basically doing public chats until private spaces are in a better spot then doing private spaces for private groups.

Roomy.space is another one of these who built their own private spaces on atproto and would be worth checking out.

Also Atproto isn't inherently a bad place for this since it can be a hybrid system of on or off protocol, or using their upcoming permissioned data spaces for private data.

I think the goal here is to get the general population off Discord and moved into a more open platform.

IRC is great but I can't see the average user using it unfortunately. Every platform has its own goal, but the ultimate community goal is whatever pushes us to an open social space is a net positive imo!

They add a TON of stuff, for example payments, age control, marketing and a lot of other nonsense

i also use irc but it doesn't work for normies. there's no integrated persistant chat log, image/file upload, voice chats, replies(linking to specific message), message editing, emoji reactions, etc...

You have been using software stuck in the last century I'm afraid. IRCv3 solves all of this with the clear exception of voice/video chats. Use ergo server, the lounge or gamja as a web frontend. Motd on android feels like a current messenger (but it's partly made with ai unfortunately). irc really is a credible possibility today

The problem is that voice&video and spaces/servers are necessary for how most people use these sorts of chat apps nowadays

You must have never tried irc in conjunction with Convos or The Lounge

Edit: Fluxer is a usable alternative https://fluxer.app

i haven't seen Convos before, thanks for sharing.

i've seen The Lounge before while looking for a discord alternative sometime ago, but i skipped it because there doesn't seem to be replies, editing, reactions, file/image sharing. i have to admit i only tried their Demo link, perhaps libera just doesn't support those IRCv3 features?

haha yeah editing still isn’t a thing in irc but image upload, replies and voice/video (convos uses jitsi) are, totally understandable if those are roadblocks.

Libera is probably your best best for IRCv3 so yeah there is a reason the industry moved to xmpp (LoL Facebook Nintendo Zoom).

I'm not a believer of push notifications, so I leave motd open in the background, with maybe a few hundreds messages a day and it consumes 1% of my battery. I know it's not an answer, sorry 😅

Yes absolutely. Which means that irc is a good platform to build on.

I get that, the feature here is realtime messages and notifications, which irc and correct apps provide, not push notification itself.

I wouldn't call it a "solved" problem... I don't use Fluxer but from what I read in online discussions it's something that's currently a pain point since they're currently trying to overhaul the system
