Danke, Tobias. Grüße aus dem Nachbarlandkreis 
Appreciate the quick response. I’m totally aware of costs on self hosted instances and I agree that the pricing is fair for small teams. Unfortunately teams are often bigger (and still don’t have the money) which drives costs apart quite quickly between self hosted but open source and hosted and on a per user base.
But I really didn’t want to opt against the pricing model. It’s totally fair and I think you’ll be having some good success with it. I was always missing something that is as accesible as Slack or Discord but more organized and structured - this could be the right approach.
I will definitely give it a check at some point in the future.
