Online collaboration has become a critical driver in business success—but which tool is the best fit for your organization’s needs? This side-by-side comparison chart will give you a snapshot view of what the major contenders have to offer.

More about the tools:

Since the launch of Slack in August 2013, real-time workplace communication tools have become increasingly popular, displacing email–in part–as the way to get things done. However, organizational, project, or budgetary requirements make it wise to consider the growing list of Slack competitors.

For organizations that have a preexisting subscription to Office 365, Microsoft Teams may be a more logical choice. Naturally, as a Microsoft product, it is more tightly integrated with Office and OneDrive. Teams is also the only communication tool that natively supports the ability to call out to landline and mobile phones in the United States. This feature is inherited from Skype for Business, which Teams is based on. Given the already steep price of Office 365, Teams may be worth considering over other alternatives as the product is already being paid for. Though this feature was not available at launch, Teams has implemented guest access to allow consultants, freelancers, contractors, and others not covered under your organization’s Office 365 subscription to collaborate with your in-house staff.
