14 of the best Slack alternatives for 2021

For more than 12 million people, Slack is the first tool they open in the morning to start their work day. And it becomes the market leader in the team collaboration industry, simplifying the work of employees and increasing their productivity.

But not everyone is excited about Slack. Some prefer not to pay a premium for unlimited search capabilities (the free version limits them to the last 10,000 messages). Others prefer a self-hosted solution that Slack doesn’t offer to gain more control over their team’s communications.

Remote teams are becoming more mainstream and this is why more and more people are looking for affordable team chat tools that suit their needs.

If you’re in the same boat, check out this list of the best Slack alternatives.

In general, Chanty’s built-in task manager and intuitive user interface make the chat tool a solid Slack alternative for less tech-savvy users. However, if you’re a tech freak, Zapier lets you connect Chanty to a variety of apps, making the team chat platform more robust.
