WhatsApp vs Slack vs Rock - A Quick Rundown

You may already know about WhatsApp. More likely than not, you've already used it to communicate with your team, friends and family.

WhatsApp was initially designed for personal (more informal) communication. Nevertheless, many companies have still adopted WhatsApp to send messages to their customers or communicate among team members.

Slack on the other hand is a business communication tool used by corporate teams, usually bigger in size. The app is more often used in business environments, with fewer informal conversations compared to WhatsApp.

Last but not least, Rock is an all-in-one communication tool that alongside messaging also provides built-in task and note functionality. What makes Rock stand out is the combination of messaging with tasks, notes, files and meetings in one place.Let’s jump right into the comparison.

What apps can you integrate? WhatsApp vs Slack vs Rock

WhatsApp is primarily used for personal messaging and does not support third-party apps. This might be a dealbreaker for you if you require integrations in your day-to-day work.

Rock and Slack, on the other hand, integrate well with a wide range of third-party business tools to help with various tasks for efficient business communication.

Google Drive, for example, is tightly integrated with Rock and can be viewed from within the app. If you are a Google Workspace user, this integration will allow you to keep your documents organized and accessible at all times.

Both Rock and Slack support third-party integrations. Team members can add context to conversations by sharing files from Google Drive, Design materials from Adobe Creative Cloud, or even hosting Zoom meetings.

Video & voice conferencing options across platforms

WhatsApp makes audio and video calling quick and easy, but there is one catch – it is only available on mobile devices. This is fine if your team is constantly on the move, but Rock and Slack provide more robust cross-platform video and voice conferencing possibilities for business communication.

There are certain benefits of cross-platform video and audio calls like screen sharing that can help you make your point more effectively. Seamlessly integrate Zoom, Google Meet and Jitsi with Rock. Meanwhile, the free Slack plan doesn’t offer Zoom integrations.

Now, let’s talk about voice messages. When your team is on the go or you need to quickly share an idea, WhatsApp voice messages come in handy.

Rock and WhatsApp both allow you to speed up voice messages, which can come in handy when listening to longer form messages. Meanwhile, Slack has a more basic audio message feature that does not allow for speeding up messages yet.

Who has the best pricing options? WhatsApp vs Slack vs Rock

It's difficult to argue with a price tag that says "free". All you need is a phone number and data connection to get started with WhatsApp. Everything else is, well, free.

You’d assume WhatsApp wins right away in the pricing category, but that might not fully be the case. Even though Rock has a paid plan, its free version surpasses WhatsApp in terms of communicating and collaborating with team members.

Rock's Free plan provides:

  1. Unlimited users, messages, uploads, one-on-one & group spaces and meetings.
  2. Collaboration functionality including tasks, notes, checklists, board view and more in every space.
  3. Free integrations to Google Drive, Dropbox, OneDrive, Adobe Creative Cloud and Smartsheet. Share as many files as you want and pick and choose which storage provider to use besides Rock.
  4. Create cross-organizational spaces. Invite anyone from any email domain, or just a phone number.

Meanwhile, the cost of Slack is a major reason why more and more businesses are looking for alternatives. It does have a free version, but it might be a bit more limiting. The free version of Slack includes:

  1. One workspace, limited message search (up to 10,000 messages), unlimited channels, and one-on-one video calls are all unlimited. Group video calls are only available in the paid version.
  2. For shared files, 5GB of file storage is provided, with limited Google Drive integrations.
  3. Cross organization messaging is not available under the free plan.
  4. Up to ten service integrations are possible. A paid plan, which starts at $6.67/user/month, is required for more integrations.

An important difference between the paid plans of Slack and Rock: per user pricing. On Slack you pay for every user that you want to upgrade. Meanwhile, on Rock it is based on spaces with advanced functionality. This means that you pay for functionality, not team size.
