Why are some companies looking for alternatives to Google Workspace?

Google Workspace is a pretty good set of productive tools and online services which can help companies bring their teams together and enhance their internal productivity. However, many organizations find its subscription plans very expensive and are not happy with Google’s privacy policy.

All the alternatives below are open-source and have all the necessary features that you would like to see in a productivity suite. Importantly, all these platforms are self-hosted and can be installed on your Linux server. 

Let’s go through the list and find the best solution for your organization.
