Looks cool, but unfortunately another company that treats single sign-on as a luxury feature, not a core security requirement by jacking the price way up to get SAML support. Companies really need to stop doing this.
I see it as an open-source product that you are free to run in whatever fashion you like, behind SSO or not. For a place for contributors to chat about an open-source project, for example, it’s hard to see how SSO is a must.
Demanding SSO from Zulip would be like demanding SSO from self-hostable Discourse, Jitsi, etc.
Single-sign-on is a large and painful feature to develop, that most people don't need, and that the companies that need it are willing to pay for. It's the perfect candidate for a higher-tier pricing structure. This makes much more sense than tiering on a feature that everyone needs.
Sso should be the default really. And as a starting point every language has openid connect implemented. Yes it needs work but surely better than the average password reuse?
For large and small companies surely the best way to maintain their users
