Microsoft Teams vs Zulip
They differ on 8 of the 12 things buyers in this category actually ask about. Here is where, and what each one asks you to give up.
Microsoft Teams
$4/seatChat and meetings bundled into Microsoft 365, so the marginal cost is often zero.
Strongest argument
Already paid for if you licence Microsoft 365 — often the cheapest viable option
Biggest objection
Threading is awkward enough that conversations fragment across chats and channels
The client is heavy, and channel/thread structure frustrates teams used to Slack.
Zulip
$6.67/seatTopic-threaded chat designed so asynchronous and distributed teams can catch up quickly.
Strongest argument
Every message lives under a named topic, so catching up takes minutes not hours
Biggest objection
Smaller ecosystem and a less familiar interface raise the training cost
The topic model needs a real onboarding push — teams that skip it revert to chaos.
