Effective team communication has always been essential to business survival and success, but the rise in remote work and the global workforce requires a new approach to team collaboration.

The instant chat messaging app Slack quickly became the standard for contemporary team collaboration–and given its intuitive, easy-to-use platform, user tagging, and notification management features, it’s easy to see why. Plus, Slack offers a robust free version, consistently adds new features like in-app calling and video chat, and integrates with top third-party tools.

However, Slack is not a perfect fit for every team. The below Slack alternatives outline the best new players within the team communication and collaboration space.

Research, open discussion, and perhaps a few trial runs will lead you to the best team collaboration solution.
