LibreOffice vs Microsoft 365 (2026)

By Noahlast updated

Verdict: Choose LibreOffice if you want a full six-application office suite with no subscription, no account, and no feature paywall, ever. Choose Microsoft 365 if you need native real-time cloud co-authoring, mobile apps, and Copilot AI baked into Word, Excel, PowerPoint, and Outlook. Price and cloud collaboration are the deciding factors: LibreOffice costs $0 forever while Microsoft 365 starts at $9.99/month, but only Microsoft 365 offers real-time multi-user editing and official iOS/Android apps.

Choose LibreOffice if…

  • You want a complete office suite (word processor, spreadsheet, presentations, plus a desktop database app in Base) without ever paying a subscription
  • You need to inspect or modify the source code, since LibreOffice is open source under MPL-2.0/GPL/LGPL
  • You're on Linux, where LibreOffice is the default suite on many distributions and Microsoft 365 has no native desktop app
  • You don't need real-time multi-user co-authoring and mostly edit documents solo or hand them off sequentially

Choose Microsoft 365 if…

  • You need native real-time cloud co-authoring across Word, Excel, and PowerPoint with colleagues editing simultaneously
  • You want Copilot AI drafting and rewriting text, building spreadsheet formulas, and summarizing email inside the apps you already use
  • You need official mobile apps for iOS and Android, which LibreOffice doesn't offer under its own brand
  • You want 1TB or more of pooled cloud storage per person bundled with the subscription rather than managing your own storage

LibreOffice vs Microsoft 365 pricing: which costs less?

LibreOffice costs less because it is free forever, while Microsoft 365 starts at $9.99/month with no permanently free tier.

LibreOffice has no paid tier at all: the full six-application suite is a one-time free download with no account or subscription required. Microsoft 365 Personal is $9.99/month ($99.99/year), Family is $12.99/month for up to 6 people, and Premium is $19.99/month with advanced Copilot agents. The only non-subscription Microsoft option is the $179.99 Office Home 2024, a one-time purchase that never receives feature upgrades and excludes Copilot.

Which is easier to use, LibreOffice or Microsoft 365?

Both carry a low learning-curve rating in the data, though LibreOffice's interface is described as more dated than Microsoft 365's.

Does LibreOffice support real-time collaboration like Microsoft 365?

No, LibreOffice has no native real-time cloud co-authoring, while Microsoft 365 builds simultaneous multi-user editing directly into Word, Excel, and PowerPoint.

This is LibreOffice's most cited weakness against Microsoft 365 and Google Workspace: multiple people can't edit the same document at the same time inside the app. Microsoft 365 supports this natively through OneDrive-backed cloud documents. Teams that need to co-edit documents simultaneously will find Microsoft 365 the more capable option; those who mostly hand off documents sequentially or work solo won't notice the gap.

Can LibreOffice replace Microsoft 365?

Yes for individuals and organizations that don't need real-time cloud co-authoring or Copilot AI, since LibreOffice opens and edits Microsoft's .docx, .xlsx, and .pptx formats at no cost.

LibreOffice covers the core writing, spreadsheet, and presentation workflow free of charge, plus a desktop database tool (Base) that Microsoft 365 doesn't offer at the consumer level. It falls short for teams that need native simultaneous multi-user editing, Copilot AI assistance, official mobile apps, or perfect fidelity on complex Microsoft-format documents with advanced macros or specific chart types.

Strengths and weaknesses

LibreOffice

Pros

  • Completely free with no subscription, account, or feature paywall, including a desktop database app (Base) most competitors omit.
  • Open source (MPL-2.0/GPL/LGPL) with an active community and frequent releases.
  • Broad Microsoft Office format compatibility (.docx, .xlsx, .pptx) for opening and editing existing Office files.
  • Runs on Windows, macOS, and Linux, and is the default suite on many Linux distributions.

Cons

  • No native real-time cloud co-authoring like Microsoft 365 or Google Workspace, so simultaneous multi-user editing isn't built in.
  • Complex Microsoft-format documents (advanced macros, some chart and font rendering) can lose fidelity when converted.
  • No official mobile apps for iOS/Android under the LibreOffice brand.
  • Interface and default styling feel dated compared to Microsoft Office or Google Workspace.

Microsoft 365

Pros

  • Bundles full-featured desktop and web apps (Word, Excel, PowerPoint, Outlook, OneNote) in one subscription.
  • Generous cloud storage — 1TB per person, up to 6TB pooled on Family and Premium.
  • Copilot AI assistance is built into Word, Excel, PowerPoint, and Outlook rather than sold separately.
  • Family and Premium plans cover up to 6 people under a single subscription.

Cons

  • No ongoing free tier; canceling the subscription removes access to the desktop apps entirely.
  • The only one-time-purchase option (Office Home 2024, $179.99) lacks Copilot and never gets feature upgrades.
  • Advanced Copilot AI agents require the $19.99/month Premium tier, a $10-20/month jump over Personal.
  • Reviewers cite setup and admin complexity, especially for business deployments.
