Do you mind me asking if you'll be self hosting mattermost? If so they're moving to a 1000 User hard limit for self hosted instances. https://forum.mattermost.com/t/solved-is-there-any-limitatio...
Slack has raised our charges by $195k per year

#392Earlier quoted context omitted.
Mattermost also has a tutorial to import your slack messages https://docs.mattermost.com/administration-guide/onboard/mig...
I have been running a Mattermost instance with a few thousand users for years now. It really hasn’t required any maintenance at all beyond incrementing the version number. They are starting to tighten the screws (showing admins a warning if you have over 2500 users), but it’s still looking good for a few years before I need to act on that.
Notably, Mattermost can be forked to a community edition if the team behind it does anything too user-hostile. It's a fine balance for them to keep their "team edition" nudging users to a supported edition without being so annoying that users are motivated to make that community edition.
I have other reasons to want a community edition personally, but sadly they've been successful enough thus far that there isn't enough interest from other developers to make it happen.

#393That's a 40x increase all at once with a very short grace period, it's bait-and-switch territory. If only 2.5% of targets pay the ransom, Slack breaks even on this racket, so in absence of any protection this strategy is most likely profitable for Slack. This is something you pull if you want to squeeze in the short term, and don't mind losing customers.
Thanks for doing the math. Imagine being the analyst who was paid to optimize this or (infinitely worse?) the executive who demanded it.
Should be enough for the state to take custody of their kids.

#394Since you're a nonprofit that teaches coding, it could be a great time to consider self-hosting a FOSS chat tool. Suggestions: Campfire [0] or Zulip [1]. Also, if the data in chat is being held hostage, the org might be using chat wrong. Right tool for right purpose. If starting over, perhaps consider if it would make sense to put that documentation or whatever it is that will get "lost" from Slack into a wiki or rep…
I'm in Hack Club, the team is moving all of us to self-hosted Mattermost. It is unfortunate that we have to re-code so many things though.
I've never used Mattermost before today. After checking out their site, I can see they are also a for-profit company. What does Mattermost offer that Slack does not, other than a bill lower than $195K/year?

#395I genuinely don't understand this from a business perspective. They were getting money, then they jacked up the price to a degree that all but guarantees they will lose them as a customer. Sure it's small potatoes but they could have done like 30 seconds of research to see if the customer even has the means to pay before strong-arming them and getting nothing. Honestly just a heuristic that says any company simply on…
Agreed, it's bizarre. $5,000/yr > $0/yr. There's no way the operational costs from this specific customer exceed $5,000/yr.
Because the calculation is that if:
N customers * X% drop out rate * $200K > N * $5K
Then its a profitable operation for slack.

#396+1 to the other comments recommending Zulip over Mattermost. The threading model is fantastic. Also, for a non-profit teaching coding note that they regularly have interns under the Google Summer of Code program and it's open source, so the students can even help with it. https://summerofcode.withgoogle.com/programs/2025/organizati...
I believe we considered Zulip, but determined it's mobile app to be poor.
When was it looked into? The Zulip mobile app was rewritten in Flutter recently, that version was in beta for several months and was finally made the default Zulip app about a month ago. I haven't used Mattermost so can't compare, but the Flutter Zulip is much more responsive and nice than the previous Zulip app.

#397Slack is doing questinonable things anyways. When we migrated away from it to Teams, I wanted to export the workspace to be able to look stuff up in case we need it. We are a very small company and had the smallest plan, no chance, export only with the expensive plan.
Since I'm located in europe, I thought of just doing a data request based on GDPR (at least for my messages). They declined it and referred me to my organization, since we are in charge of fulfilling such requests (how would we even do that if there's no functionality for it?). Absolutely ridiculous.

#398i wish discord worked better for work
I wish it worked worse and people stopped used it as a replacement for forums.

What's poor about it? I've used it for a while and didn't notice anything bad.

#400Hi! An official announcement from Zach Latta has been made in the Hack Club Slack. We're moving to Mattermost now and we're trying to export all messages, DMs, etc. Disclaimer: I am a member of Hack Club's Slack and NOT a working personnel there.
Good news and good luck with that, hopefully Mattermost will behave better.
Make sure to warn others of Slack/Salesforce, customers need to have a voice and this behavior must become prohibitly expensive for Salesforce.
