Best European Alternatives to Microsoft 365 and Word (2026)
Microsoft 365 keeps your documents in Microsoft's cloud, run by a US company under US law. The personal plans are a yearly subscription, and Microsoft has raised their price to bundle in its Copilot AI. European office suites open and save Word and Excel files, with your documents kept under European law.
Replace Microsoft 365 and Word with a private productivity suite based in Europe. Compare Collabora Online, CryptPad, Infomaniak kSuite and more, all operated under European privacy law.
