Free Alternatives to Microsoft 365
No Subscription Needed
Stop paying $9.99/month for Microsoft 365. These free and open-source alternatives give you the core features without the subscription.
Microsoft 365 at $9.99/month ($119.88/year) bundles Word, Excel, PowerPoint, and Outlook. LibreOffice is a free, open-source office suite that handles the same document formats.

For most users, 80% of their office work is basic document editing, spreadsheets, and presentations — all of which LibreOffice handles well. Microsoft 365's main advantages are advanced Excel features, Outlook integration, and 1TB OneDrive storage. If you don't need those specific features, free alternatives save $120/year.
The following free and open-source alternatives have been evaluated for features, usability, and long-term viability. Each one eliminates the $$9.99/month subscription cost while keeping the core functionality you need.
