Best Open Source Office Suites

Open source office software has come a long way in recent years, so choosing free software over expensive proprietary software doesn’t mean you’ll lose features and support.

Today’s open source office productivity software is feature-rich and provides access to online documentation and large communities of users and developers.

Choices abound, but few are worth your time (and even fewer, your money). Fortunately, there are capable alternatives available for both Windows and MacOS.
