Leaving Slack For Zulip – What You Need To Know

Leaving Slack For Zulip

We’ve been considering leaving Slack for a few years. While the free Slack plan was always limited, the 90-day limit recently imposed made us realize we overstayed our welcome.

If we were to leave Slack, it would have to be an open-source chat solution. As an open-source project, we try to support and use other open-source projects. This was a good opportunity to do just that.

During our research, we considered several options:

  • Matrix with Element suite of apps. A federated messaging protocol and apps.
  • Mattermost. A close alternative to Slack.
  • Rocket.chat. Another popular open-source chat platform.
  • Zulip. An open-source chat platform with a hosted cloud version.

We are a small open-source community and team, so our needs are simple:

  • Ability to have channels (streams or rooms) for different topics.
  • Unlimited message history and search.
  • Apps for all devices, including Linux.
  • The easier it is to maintain and use, the better!

Why Zulip?

After careful consideration, we chose Zulip to replace our Slack. Let’s quickly discuss why:

  • Zulip is an open-source chat software. 
  • It offers full message history and quick search capabilities.
  • It has apps for all devices – Windows, Macs, Android, iOS, and Linux.
  • It even offers topic-based threading within streams (channels).
  • Zulip supports open-source projects.

The last box Zulip checked for us was the ease of management. While it can be self-hosted for free, Zulip sells a Cloud version to businesses. The Zulip team was kind enough to sponsor a Standard plan for ClassicPress. That’s $8/user/mo value!

This means the ClassicPress team doesn’t have to spend money on a server to host Zulip (or any other chat app) while we get the benefits of Zulip’s Standard plan, which includes:

  • Unlimited search history.
  • 10GB per user file storage.
  • and all other chat features.

Our resources will continue to be focused on the core development and ClassicPress infrastructure, a win for our community!

What You Need To Know

There are a few things you need to be aware of so you know what to expect:

  • We are migrating Slack message history from 2018 until August 1st, 2023.
  • All the user accounts will be migrated, which includes your email.
  • Direct Messages (DMs) will not be migrated.
  • Your Slack account will be migrated to Zulip, but your password will not! For security, Slack passwords are not migrated.
  • ⚠️ When migration is complete, we will send a password reset email to access your Zulip account. ⚠️
  • You also will have an option to manually reset your password using the same email address you used on Slack.

What’s Next

While we are migrating to Zulip, here are a few things you can do:

  1. We recommend you check out Zulip’s Getting Started Guide to learn more.
