Zulip connects communities of all kinds by making it easy to chat real-time or async. Why are communities choosing Zulip over Discord, WhatsApp, Slack, Facebook, and other apps you might consider? Zulip provides: - A platform that helps [community members to connect](#encourage-all-community-members-to-connect-real-time-or-async) and [communities to grow](#grow-your-community). - A comprehensive [moderation toolkit](#a-moderation-toolkit-that-offers-everything-you-need). - Control over [how to sign up](#as-public-as-you-want-it-to-be), and a [public access option](#as-public-as-you-want-it-to-be). - [An open-source platform](#open-source-platform-where-your-data-is-yours), where your data is yours. - [A free version, discounted pricing, and full sponsorships](#free-version-discounted-pricing-and-full-sponsorships-available). > The core of the Recurse Center is the community, and the core of our online > community is Zulip… Switching to Zulip has turned out to be one of the best > decisions we’ve made, and it’s impossible to imagine RC today without it.

A forum-style experience makes it easier for them to participate async.

With conversations organized by topic, Zulip combines the best of both worlds. You get seamless real-time communication, with a chronological feed of messages in each conversation, typing notifications, presence indicators, status emoji — everything you might expect from a modern chat experience.

At the same time, community members can read one conversation at a time, so it's easy to circle back to a topic hours later, the next day, or next week.

It's a game changer. > 🧑‍💻🗨️👩‍💻 > — Dan Allen (@mojavelinux), [June 29, 2021](https://twitter.com/mojavelinux/status/1409702273400201217)   ## A moderation toolkit that offers everything you need Zulip's [moderation toolkit](/help/moderating-open-organizations) lets you: - Skim the [combined message feed](/help/combined-feed) or [browse conversations](/help/recent-conversations) to find where moderator attention is needed. - Keep discussions organized by [moving](/help/move-content-to-another-channel) conversations, or [splitting](/help/move-content-to-another-topic) them when they digress. - Address bad behavior, for example by [banning](/help/deactivate-or-reactivate-a-user) the offender and [deleting](/help/delete-a-message) their messages. - Fight spam in an open community, for example by [prohibiting disposable email addresses](/help/restrict-account-creation#dont-allow-disposable-domains). - [Restrict permissions](/help/restrict-permissions-of-new-members) for new users. Community members can [mute](/help/mute-a-user) anyone who's bothering them. ### Delegate moderation responsibilities Permissions in Zulip can be granted to any combination of [roles](/help/user-roles), [groups](/help/user-groups), and individual [users](/help/introduction-to-users), so trusted community members can help moderate. In larger communities, different people can [administer](/help/configure-who-can-administer-a-channel) different channels. ## Grow your community ### Lots of activity, but no chaos On Zulip, dozens of discussions can happen in parallel, without getting in each other's way: Zulip's [channels](/help/introduction-to-channels) and [topics](/help/introduction-to-topics) create dedicated spaces for each conversation. Participants can ask a question or kick off a new discussion without having to worry about interrupting. > Zulip helped the FHIR community grow from a tiny group of dreamers to 500 > active users sending 6000 messages per month, all driving the creation of > better healthcare standards. Zulip’s topic-based threading helps us manage > simultaneous discussions with clarity, ensuring the right people can pay > attention to the right messages. This makes our large-group discussion far > more manageable than what we’ve experienced with Skype and Slack. > — Grahame Grieve, founder, FHIR health care standards body ### Occasional participants welcome Community members often have just a bit of time to participate, and folks with the deepest expertise might also be the most busy. To stay connected with your group, they need to quickly discover conversations that are interesting to them when they drop by. With traditional chat tools like Discord or WhatsApp, occasional participants usually skim just the last few messages. If those messages don't spark interest, they'll bounce for the day, and eventually stop coming by altogether. Zulip's list of [recent conversations](/help/recent-conversations) offers a quick overview of what's been happening in your community. It's easy to scan the list of topics to find which ones you want to dive into. > I had never engaged with the Changelog podcast community in Slack because I > always got too overwhelmed with the linear flow of conversations. Topic based > systems are such a fresh breath of air. > — [Siddhartha Golu](https://www.siddharthagolu.com/), > [Changelog](https://changelog.com/podcast) community member ### Many ways to participate You can use Zulip from the browser, a [desktop app](/apps), and Android and iOS mobile devices.

There are convenient [keyboard shortcuts](/help/keyboard-shortcuts) for all the common actions. Zulip's UI is translated into over two dozen [languages](/help/change-your-language). ## As public as you want it to be Your community can require an invitation to join, or you can [allow anyone to create an account](/help/restrict-account-creation#set-whether-invitations-are-required-to-join). You can use: - [Private channels](/help/channel-permissions#private-channels) for conversations only some community members should have access to (e.g., discussions among organizers). - [Public channels](/help/channel-permissions#public-channels) for conversations all community members can see. - [Web-public channels](/help/channel-permissions#web-public-channels) for discussions anyone on the internet should be able to read without logging in.

Here are some reasons why folks choose Zulip over other apps you might consider for hosting your community. > Zulip makes all my Slack and Discord communities feel tedious by comparison. > > — AJ Kerrigan, [Changelog](https://changelog.com/podcast) community member ### Group chat apps (WhatsApp, Telegram, Signal, Messenger, etc.) Group chat apps can be convenient for small or low-activity groups, but managing an active community quickly becomes unwieldy. Having more than one conversation at a time in a single group chat feels chaotic, and membership management is a big pain if you try to solve that by using several group chats. ### Discord In Discord, only the latest messages are easy to read and reply to. Many less frequent participants will miss much of what's happening in an active community. You're also subjecting community members to intrusive in-app advertising, even if they purchase Discord's paid plans. ### Slack Like Discord, Slack doesn't work well for less frequent participants in an active community. Additionally, on Slack's free plan, messages are hidden after 90 days, and are permanently deleted after a year. Slack's paid plans are generally unaffordable for community use. ### Facebook On Facebook, your relationship with your community is mediated by algorithms: even replies to a user's own post are by default resorted and partially hidden from them. From Meta's perspective, advertisers are the customers, and your attention is the product being sold. > I highly recommend Zulip to other communities… Slack is a no-go for many due > to not being FLOSS, and I’m concerned about vendor lock-in if they were to > stop being so generous. Slack’s threading model is much worse than Zulip’s > IMO. The channels/topics flow is an incredibly intuitive way to keep track of > everything that is going on. > > — RJ Ryan, Mixxx Developer
