It's also not a coincidence that Slack is neutering the ability to access channel history via the API very soon. With a very generous rate limit of 2 requests per minute I believe it was and a max of ~10 messages. This is already enforced for new marketplace apps and will apply to all apps starting in March according to their docs.
I'm surprised GDPR has nothing to say about this. You should have the right to your data, but I suppose that doesn't extend to companies?

#382You could rent a server + hire an infra engineer full time to manage chat for just this amount of money

#383+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...
Mattermost has threads, though they work different from Zulip.
I haven't used both extensively, and for an open community like Hack Club, I suppose it's possible Zulip may even be a better fit. Mattermost will offer a much more direct migration path from Slack however.
I'm curious what makes some recommend Zulip so highly over Mattermost.

#384I really wish this post had more details. How was the price computed? If Slack charging per user, how did this organization have so many users? Why is their new provider more favorable in pricing? If Slack was previously offering a nonprofit discount, what happened to it? Did they decide that this organization was ineligible, or are they shutting it down in general?
The price came out of nowhere for Hack Club. Slack had a unique agreement, also lowering the minimum age, with this specific nonprofit. I'd argue that for their scale, 200k/yr from 5k/yr with a week of warning is absolutely crazy. And I'm talking from experience - I got this message literally today, out of the blue, that after eleven years, we had to migrate within days. The community is so much larger than I imagine…
Imagine your landlord increased the rent by 4000% and it's due in 5 days or you're out on the street.
Sure, they have the right to increase their prices, but there should be at least a month notice for something like this.

#385We're using teams in my new company, which is awful for textual communication (lacks threads in chats, groups are more like old forums than new IM). I've been experimenting with self-hosted Mattermost but it seems that it also requires paid license in some situations (e.g. does not have groups for some reason in the free version). I was unable to find another system. Would anyone recommend me something?
But it’s there. I’ll give that the Microsoft, they start out incredibly crappy and do keep iterating until it’s somewhat usable.

#386> Anyway, we’re moving to Mattermost. This experience has taught us that owning your data is incredibly important, and if you’re a small business especially, then I’d advise you move away too. Sounds about right, sad to hear that it caused so much strife though. Meanwhile, did a bit of a test drive in my org with Mattermost, devs were mostly okay with it, but it was decided from top down to go with Teams instead. Won…

#387I was ready to be unsympathetic - too bad for the company - but then I read TFA and it's a rug pull on a nonprofit teaching coding to kids.... https://hackclub.com/ (They do help clubs sell things, taking "7% of income", so they do have a revenue stream, but the money that Slack wants would pay a veritable army of student interns.)

I would love it if future folks can write their own random scripts without needing a developer to do it for them.
I would love to see more people writing software. There will always be advanced work that needs doing. There will always be larger challenges.
I want the world of the future, where every 10-year-old knows calculus and python and is incredibly capable, and then I want to see the future we get when they grow up.

#388Earlier quoted context omitted.
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.
mattermost is so so so clunky and uncomfortable, but hey, it's free...
Setting up Mattermost was one of the best decisions we've made with regards to our tools.
