Why teams switch from Zulip
Docs live with the conversation
Pages hold specs, runbooks and decisions with tables, images and Mermaid, edited together and linked straight from chat.
Channels and threads people already know
No new mental model to teach: channels, threads, DMs and one inbox for everything that needs you.
Your workspace is an MCP server
Any MCP client can read and write channels and pages, and call every installed connector, through one code-mode tool.
Who should pick Zulip
Zulip is excellent for teams with lots of parallel, asynchronous discussion. Messages are organized into topics inside each channel, so catching up after a day away is fast, and conversations stay findable. It is fully open source, runs in Zulip’s cloud or on your own servers, has desktop and mobile apps, a long list of native integrations and a well-developed set of keyboard shortcuts. Open-source projects and many non-profits can get Zulip’s paid cloud plan sponsored. If you want to self-host, or your community already thinks in topics, Zulip is a great fit.
Who should pick Hasarak
Topics take some getting used to, and teams coming from Slack or Teams often prefer plain channels and threads. Hasarak keeps that familiar model and adds an inbox that collects mentions, thread replies and DMs. It also keeps docs inside the workspace: pages with tables, images and Mermaid diagrams, open as a tab next to the channel. And the workspace is an MCP server, so your agents and scripts can work with channels, pages and connectors.
Moving from Zulip
There is no Zulip importer. A common pattern is to turn your busiest channels into Hasarak channels and long-running topics into pages. Zulip’s outgoing webhooks map well onto connectors, which are one HTTP endpoint each.
