Slack Alternatives

The 12 Best Slack Alternatives for 2021

Slack has made quite a name for itself over the years. Starting out as an internal chat tool to keep a small team of gaming developers connected, Slack now boasts 12 million daily active users, half of whom are paying customers. That makes Slack the fastest-growing startup in history, not to mention one of the leading instant messaging apps for business.

But that doesn’t make Slack a one-size-fits-all platform. Whether you’re using it now or considering it for your business, it’s helpful to have some Slack alternatives in mind. Every team is different, and Slack may not be the best answer for yours.

Why Is Slack So Popular?

In a word, integrations. According to Slack, the chat software connects with more than 2,000 other tools and apps.

Slack delivers a social-media-like user experience through a hip interface that’s filled with notifications, emojis, GIFs, memes, and other such goodies. Slack also makes strong use of user feedback, taking customer suggestions on board in order to grow more iteratively.

Slack Isn’t without Drawbacks

Slack’s success and popularity are undisputed. The same goes for Slack’s top-dog status in the integrations category.

That said, those integrations render many of Slack’s capabilities a result of other apps and technologies. And if your team isn’t making use of those integrations, you’re practically pouring money down the drain, because Slack isn’t cheap.

  • It’s expensive – At $6.67 per user/month for Standard and $12.50 per user/month for Plus, Slack is out of reach for many startups or small to medium-sized enterprises. There’s a freemium version, but that limits you to 10K searchable messages and 10 integrations.
  • It’s complicated and disruptive – If you’re part of multiple teams or groups, you face separate workspaces for each team and separate logins. That’s a lot of buried messages and missed details. What’s more, anyone who posts a message resulting in a thread then gets notifications about replies. And if you’re thinking of turning off notifications, other team members can bypass your Do Not Disturb mode.
  • It may not be completely private – Questions have been raised surrounding Slack’s handling of user data, as well as the threat that the ever-growing number of third-party app integrations pose to the platform and the organizations using it.

The Best Slack Alternatives for 2021

As you can see, Slack isn’t without drawbacks. Luckily, this is the golden age of communication and there are loads of alternatives to Slack, each offering distinct capabilities to suit teams of all sizes and functions.

Below, we’ll help you sort through them so you can make the best choice for your business.
