Just looked to their self hosted plans:

    - No limitation on search, members, etc.
    - 10 user limit for mobile notifications, can be relaxed via community (for non-profits, FOSS projects, etc.)
    - SAML/LDAP *support* is available, you can configure it. They won't provide answers to your questions.
    - Actually, all Zulip features are enabled sans Mobile Notifications, but for most of them, you're on your own. If you know what you're doing, it's not a problem, I assume.

IOW, for self-hosted plans, you pay for support, not the software. a-la early RedHat model.

This is false, SAML and LDAP are available. Zulip self hosted has all features with no restrictions, except for mobile notifications which require a subscription for $3.50/u/m (unless you are less than 10 users or are not a non-profit of any kind)

It’s a bit odd though that Zulip charge $ for mobile notifications but still don’t have basic end-to-end encryption for those push notifications .

It's a mix of "because they can" and "because they need to maintain infrastructure for mobile push".

The feature is deployed in the server, mobile clients are still pending the release iinm. But it's coming.

> unless you are less than 10 users or are not a non-profit of any kind

They only give free accounts to non-profits with zero paid staff.

I stand corrected. SAML & LDAP is free in zulip.

What restrictions have you hit ?

Seeing their pricing page, mobile notifications for upto 10 users is too less.

But you mentioned similar...this is a discussion about message limits (and saml ?). Those are free for self hosted.

Push uses _their_ services. That's why it costs $$$. But you can build your own apns endpoint and plug into that at that volume

Push costs pennies. It's an arbitrary restriction.

If you want to run your own push for pennies all you have to do is compile the client yourself.

I'm not going to recompile and redistribute a binary outside the Play Store.

Then your piggybacking on their infrastructure. I don't think they are unreasonable. "It can be done for pennies, but I won't" sort of implies that it does indeed take more than pennies worth of effort.

Then you pay for it. Nothing stops you

That's precisely my point. It's an arbitrary rent-seeking restriction.

Publishing an app in popular app stores, for an organization, requires several $100 in annual fees. That’s before any mobile app is even published.

At this point I think he's just trolling. Nobody can be this entitled

It's a yearly fee that amounts to a couple hundred dollars. That's about an hour of an engineer's salary. Zulip's customers make this less than a fraction of a fraction of a fraction of a rounding error.
