Oh yeesh. If I ranked chat platforms, Mattermost would barely be above Slack. It's pathetic that Discord runs circles around Mattermost, Slack, and Matrix for practical usability, features that make it possible to actually use with teams (not Teams). Mattermost still can't do follow System Theme, (and Slack requires you impersonating Chrome). Of course neither can Gmail. Salesforce and Google are such tiny companies though, so I sympathize. It's craaazy what shit we put up with.

I wonder why Zulip isn't mentioned more in these comparisons. Personally I would pick Slack over Mattermost any day in terms of sheer usability, corporate lock-in notwithstanding. I find Discord's UX to be pretty awful in terms of visual clutter and notifications demanding attention - constantly being notified to subscribe to Nitro etc.

  Discord was not in consideration due to all the paywalled features and the lack of control, as well as locking bots behind admins (as hackclub is a community of programmers, we encourage all users to make their own bots to improve the community) We discussed zulip a bit before deciding on mattermost, but the very subpar mobile app of zulip caused us to not go with it

    > We discussed zulip a bit before deciding on mattermost, but the very subpar mobile app of zulip caused us to not go with it This keeps being repeated, but didn't Zulip just roll out[0] a brand new mobile app? Are you sure that was the app that was evaluated? What specifically was "subpar" about it when you tried it? Given the extreme limitations that Mattermost is trying to impose on the free self-hosted solution (250 users maximum!), Zulip seems like it needs to be considered again. I have not really had a chance to use either Mattermost or Zulip, I'm just pointing out what I see as an obvious mismatch between Hack Club's needs and what Mattermost provides.

      We just evaluated zulip as well and the mobile app was extremely bare bones. Also, I liked the UX of the web but others felt it was way too technical to give to our staff (some of whom will really struggle with any kind of change). I haven’t really decided yet though. Has anybody had a success with Zulip with nontechnical? I’m looking at mattermost now but it just seems to be a different point on the enshittification arc.

        Regarding the latter sentence, that's if you treat it like a service. If you want active support as well as developers to work on it constantly, someone has to pay them. If, however, you've evaluated the product and are happy with it as-is, and consider that you're literally a community of coders if you were to want some tweaks, then there cannot be an enshittification arc because you can use the current version indefinitely under the current terms I find it strange that people treat open source software like a free service. It's a free product, usually stating explicitly that "there is no warranty express or implied" in full caps. Any future improvements they release for free are worth celebrating, but not an entitlement they might price you out of by becoming "shit" all of a sudden

        I'm plenty familiar with Open Source and do contribute as well. But I would also be paying for Zulip if we were to move the company to it. I think you missed my meaning.. Mattermost is open core and recently removed things from their community version. Also, it's really not cheaper given the features I need, so my concern is that I'm just jumping providers to another company that'll eventually pull the same rug. I like and want to contribute to Zulip to avoid that problem but am not sure if the product experience will work for my particular non-technical users.

        Zulip's product lead here. We hear from a variety of folks that they've had a good experience with onboarding to Zulip, https://zulip.com/case-studies/gut-contact/ https://zulip.com/case-studies/gut-contact/ being a good example. That said, the mental model for using Zulip is a bit different from other chat apps, and I think it helps a lot to approach onboarding with intention. Making the experience of getting started with Zulip more smooth has been an ongoing priority for the past couple of years, and we've got more in the works. If there are particular aspects of the app that felt too technical, I'd love to get the feedback.

  I think Zulip is missing out on a lot by not having a "complaint" (SOC2-type2, etc) offering. I think Zulip is brilliant. Discord at least has "forums" for forced threaded discussions, and the in-room threaded conversations work far better than Slack or Matrix's.

Funny. Using Discord through Firefox I can't even copy links out of a conversation. Additionally, for some reason as of two weeks ago every time I click on a channel name it opens in a new tab. I'm not sure what that's running circles around, but I'm guessing not Mattermost.

  The mobile app is also buggy as hell. Notifications of direct messages (when someone wants to reach you personally) work only sporadically whereas in group chats they're reliable. Then when you click one of those group ones, it opens the group chat, flashes you the message, then loads the rest of the history, scrolls you down, and marks the whole chat as read. I've eventually found that you can find it again by going out of the chat and to your in-app notifications and tapping it there again. Then iirc to reply, you need to click some "open in chat" option (while you're already literally viewing the chat) and then it seems to scroll and show you the message correctly. Or maybe that latter thing was from search results, idk I'm also pretty sure it silently deletes old direct message chats. I'm missing some that I really thought existed. Don't fault them for deleting things btw, seeing all the (literal and figurative) shit that thousands of teenagers post in this server I was helping out on, but it shouldn't be silent
