Great for developers

  • Format code as code: Messages take Markdown formatting, including code blocks, making it super easy to discuss some code or paste an error message.

  • Clear permalinks: Have a design discussion in chat and want to link to it in your bug tracker or a commit message? Two clicks makes a permanent link. The URL transparently shows where the discussion happened, and for everyone who clicks through, Zulip's topic threading provides a focused view on that conversation.

  • Easy custom linkification: Want to refer to issues or code reviews with short notation like #1234, T1234 — or any other style of your own? Set up any regex as a custom linkification filter for your organization.

  • Plays well with others: With 60+ integrations including GitHub, Travis CI, JIRA, and Stripe, chances are Zulip already integrates with the tools you use every day; and our API makes it easy to add more.

  • Everything in its place: Troubleshooting in chat for users or new developers becomes much more manageable with Zulip's topic threading: each issue in a channel can be discussed in its own thread.

Great for productivity

  • Clearer conversations: With Zulip's unique model of threading by topic, your community can have more than one conversation in a channel at the same time, without the confusion and talking-over caused by traditional models like IRC and Slack.

  • Full service: No need to settle for a limited "try it out" tier. You're welcome to host Zulip yourself, or sign up at zulipchat.com for commercially-supported hosting — free for open source projects.

  • Fast full-text search: Feeling dejà vu about an issue someone's reporting? Searching your full message history is a snap.

  • Proven model: Stop by chat.zulip.org, Zulip's own development community, to see it in action for a large project with ~5000 messages/week, essentially all of it productive developer discussion.

Great for open communities

  • Web, mobile, desktop: Sleek, modern apps for every platform make Zulip an inclusive choice for everyone in your community.

  • Walls optional: Take down the barrier to participation created by making people interested in your community ask for an invitation before they can enter — use one checkbox to open your Zulip organization for anyone to join.

  • Badges: Want to link to your Zulip organization with a nice badge in your README? Done.

  • Scale: Zulip scales well to large communities — it's loved by communities as large as 1000 users and beyond.
