Zulip

Zulip is a channel-based team chat service offered in hosted and self-hosted forms. It suits teams that need guest participation, broad service integrations, or control over deployment; teams with heavy archives or file sharing should budget for a paid tier.

Overview

Zulip centers conversations on channels, giving teams a way to separate work by project or subject instead of keeping every discussion in one stream. Guest access is useful when clients, contractors, or partners need to participate without joining the whole organization. The service is freemium, with cloud and self-hosted choices that differ substantially in storage, history, support, and minimum users.

Zulip was founded in 2012 and is headquartered in San Francisco, California. It runs in a browser and has apps for Windows, macOS, Linux, iOS, and Android. API support is also available, which gives teams another route for connecting internal tools.

Key features

Channels, guests, and integrations

Channels make topic-based organization the central working model, while guest access accommodates people outside the core team. The integration roster covers development and project work through GitHub, GitLab, and Jira; meetings through Google Calendar, Zoom, and Jitsi Meet; automation through Zapier and IFTTT; and support through Sentry and Zendesk. Slack and Microsoft Teams are included as well. This breadth is a practical advantage for teams already spread across several services, although the roster alone does not indicate how deeply each integration works.

History and files

Cloud Free includes 10,000 messages of searchable history and 5 GB of total file storage. That is workable for a small or lightly active team, but a busy workspace can outgrow the archive and shared storage. Paid cloud tiers switch to storage measured per user, making capacity easier to scale with the team.

Pricing

Cloud plans

• Cloud Free: free, with 10,000 searchable messages and 5 GB total file storage. It is the sensible starting point for small teams testing Zulip, provided the history and shared-storage ceilings are acceptable.
• Cloud Standard: $6.67 a month, billed annually, with 5 GB file storage per user. This removes the free tier's shared-storage constraint and fits teams that need a predictable hosted workspace without the larger deployment requirements of Plus.
• Cloud Plus: $10 a month, billed annually, with 25 GB file storage per user and a 10-user minimum. It is aimed at larger teams that can meet that minimum and need substantially more per-person file capacity.

Self-hosted plans

• Self-hosted Free: free, including mobile notifications for up to 10 users for other organizations. It can suit a small deployment, but the notification allowance is explicitly limited.
• Self-hosted Basic: $3.50 a month, billed monthly, with a $20/month discount for the first year. It provides a complete team chat solution and unlimited mobile notifications while supporting Zulip's open-source development, making it the clearest low-cost self-hosted upgrade.
• Self-hosted Business: $6.67 a month, billed annually, with a 25-user minimum and a $20/month discount for the first year. The minimum makes it unsuitable for very small organizations but relevant to established teams deploying their own service.
• Self-hosted Enterprise: custom pricing. It adds email, chat, and phone support; OpenID Connect SSO; AD/LDAP, SAML, and OpenID Connect group sync; SCIM user and group sync; and implementation consulting. Those controls target organizations with formal identity, provisioning, and rollout requirements.

Platforms

Zulip supports web, Windows, macOS, Linux, iOS, and Android access, plus an API. That combination covers office desktops, mobile users, and teams that need programmatic connections without restricting the service to one operating system.

Who it's for

Choose Zulip when channel separation, guest participation, and integrations across engineering, meetings, automation, and support matter more than an especially generous free archive. Cloud plans suit teams that want managed hosting; self-hosted Basic and higher make more sense when deployment control or enterprise identity features outweigh administrative overhead. The free cloud tier is best for smaller, less active teams that can stay within 10,000 searchable messages and 5 GB total storage.

Pros and cons

• Pro: Channel-based organization keeps subject-focused discussions distinct.
• Pro: Guest access supports collaboration with people outside the main organization.
• Pro: Integrations span code, project tracking, meetings, automation, and support tools.
• Pro: Self-hosted tiers provide a low-cost route to deployment control, with enterprise identity and support options at the top end.
• Con: Cloud Free is capped at 10,000 searchable messages and 5 GB total file storage, so active teams may need to upgrade.
• Con: Cloud Plus requires at least 10 users, and Self-hosted Business requires 25, raising the entry cost for small organizations.
• Con: Enterprise capabilities come with custom pricing, making that tier harder to budget in advance.

Alternatives

For a broader directory of choices, browse Team chat apps or Team Collaboration Software.

Pick Microsoft Teams instead if you need free meetings for up to 100 participants, 60-minute group calls, and 5 GB of cloud storage. Slack is an alternative when a free plan with 90 days of message history and up to ten apps matches your retention needs. Choose Zoho Cliq for a free allowance of 100 participants per group, 10,000 searchable messages, and 100 GB of organization storage. Rocket.Chat is worth considering when self-hosting and a 50-user free Starter plan are priorities. Lark suits teams seeking a Starter allowance of 20 users, 100 GB storage, 18 months of message history, and 1,000 automations per month. Discord is the better fit for communities centered on voice, video, and text chat. Wire is an alternative for teams that specifically want a fully open-source source codebase. Pumble is worth a look when unlimited users, unlimited message history, unlimited channels, and 10 GB workspace storage are the deciding limits.

Verdict

Zulip is a strong choice for teams that want topic-oriented chat, guest access, many integrations, and the option to self-host. Its main reason to look elsewhere is the constrained free cloud history and storage, alongside user minimums on higher tiers; organizations with those needs should compare the paid and self-hosted terms carefully.
