With the recent increase in remote work, many companies are having to pay for collaboration apps, such as Slack. Everyone knows Slack’s paid version is costly, but the free version is also extremely limited in functionality. Due to the limited functionality of Slack’s free plan, most companies resort to paying for Slack. See the problem?

Companies who use Slack pay more money to get work done, whereas companies who use the free version struggle to get any work done.

Slack’s Free Plan

In Slack’s free version, there is limited functionality. These limits are:

  • 10K searchable messages
  • 10 apps and integrations
  • 1-to-1 video calls

These limits prohibit companies and teams to get work done seamlessly.

But what if you could have a free alternative that delivers equal or better quality than the free version of Slack?

Here is our list of free slack alternatives: 

  1. AirSend
  2. Chanty
  3. Dino
  4. SquidHub
  6. Zulip
  7. Discord

In this blog post, we will discuss the main functionalities of each free alternative. Let’s dive into the seven best free slack alternatives.
