The verdict

Both are open-source Slack alternatives that stay quiet about paid pricing — neither publishes a per-seat number, so you contact sales once you outgrow the free option. Where they differ is how complete that free option actually is. Zulip’s self-hosted edition ships with every feature, unlimited history, and no user cap, and Zulip Cloud adds a genuinely hosted free tier (10,000 messages of history, 5GB storage) that needs no server of your own. Mattermost’s only free path is a limited-use technical-evaluation edition for self-hosting — real production use means contacting sales for Professional or Enterprise. The two also organize conversations differently: Zulip tags every message with a topic inside a channel so parallel discussions don’t collapse into one feed, while Mattermost attaches replies to a thread inbox but keeps the main channel as one scrolling stream. Pick Zulip for the more complete free tier and topic-based organization; pick Mattermost if its enterprise/government hardening or native cross-platform apps are what you actually need.

Which one should you pick?

Pick Mattermost if…

  • Pick Mattermost if you want native desktop apps across Mac, Windows, iOS, and Android alongside the web client
  • Pick Mattermost if government-grade hardening — FedRAMP, STIG-hardened images, air-gapped installs — is something your team actually needs
  • Pick Mattermost if built-in 1:1 calls with screen sharing (Professional tier) matter to you, not just messaging
  • Pick Mattermost if you’re fine starting on its free evaluation edition and contacting sales directly once you’re ready to deploy for real

Pick Zulip if…

  • Pick Zulip if you want the more complete free option — self-hosted Zulip includes every feature, unlimited history, and no user cap, at no cost
  • Pick Zulip if you want a genuinely hosted free tier — Zulip Cloud Free needs no server of your own, unlike Mattermost’s free option, which is self-hosted only
  • Pick Zulip if topic-threading — tagging every message so parallel conversations don’t collapse into one feed — is the organizing principle you want
  • Pick Zulip if you want the flexibility to move between Zulip Cloud and self-hosting later, using Zulip’s own export/import tools

Mattermost vs Zulip — questions people ask

Is Mattermost or Zulip cheaper?

Neither publishes a per-seat price for its paid tiers — both require contacting sales once you outgrow the free option. The free options themselves differ: Zulip’s self-hosted edition is fully featured at no cost for any team size, while Mattermost’s only free option is a limited-use evaluation edition.

Do I need my own server for either?

Not for Zulip — Zulip Cloud Free is a genuinely hosted option with no server required. Mattermost’s free tier is self-hosted only; a free hosted Mattermost plan isn’t listed.

Are Mattermost and Zulip both open source?

Yes — both are open source and self-hostable, though Mattermost’s higher tiers (Enterprise, Enterprise Advanced) are quote-based commercial editions on top of the open-source base.
