LibreOffice vs CryptPad
Both are free/open-source alternatives to Microsoft 365. Here's how they stack up — verified facts, no spin.
LibreOffice
TOP PICKThe mature, fully open-source desktop office suite that runs entirely on your own machine.
LibreOffice is the most complete free desktop office suite and the closest all-round replacement for the Word/Excel/PowerPoint apps. It bundles Writer, Calc, Impress, Draw, Base, and Math, runs on Windows, macOS, and Linux, and opens and saves Microsoft's DOCX, XLSX, and PPTX files as well as the open OpenDocument (ODF) formats. It is produced by the non-profit Document Foundation, installs locally with no account or cloud, and costs nothing. It is the right pick for individuals and organizations that mainly need capable offline documents and full control over their files. Its main gap versus 365 is native real-time co-authoring in the desktop apps; browser-based simultaneous editing comes from the related Collabora Online project, listed below.
CryptPad
End-to-end-encrypted collaborative documents where the server never sees your content.
CryptPad is a privacy-first collaboration suite built around end-to-end encryption: documents, spreadsheets, presentations, and more are encrypted in your browser, so a self-hosted or public server stores only ciphertext and cannot read your content. It supports real-time co-editing, shared folders, and a range of app types, and it is AGPL-3.0 licensed and self-hostable via Docker or a Debian install. Developed by XWiki SAS with public-interest funding, it also runs a free public instance at cryptpad.fr. It is the strongest choice when confidentiality is the priority; the trade-off is that it is a distinct web workspace rather than a drop-in Microsoft-format editor.

LibreOffice is Macrostack's recommended Microsoft 365 alternative, so it's our pick here.
LibreOffice
Strengths
- +Fully open-source under MPL-2.0, an OSI-approved license
- +Runs entirely offline on your own computer with no account, subscription, or cloud
- +The most feature-complete free desktop suite: word processor, spreadsheet, presentations, plus Draw, Base, and Math
- +Reads and writes Microsoft's DOCX/XLSX/PPTX as well as the open ODF formats, so files stay portable
- +Backed by the non-profit Document Foundation with a very active release cadence and large community
Trade-offs
- −No built-in real-time co-authoring in the desktop apps; browser-based simultaneous editing needs the related Collabora Online
- −Complex Microsoft documents (heavy macros, advanced pivot tables, intricate formatting) can shift slightly on import/export
- −No bundled cloud storage, email, or team-chat equivalent to OneDrive/Outlook/Teams
- −The interface and defaults differ from Microsoft's, so there is a short adjustment period
CryptPad
Strengths
- +AGPL-3.0 licensed and self-hostable via Docker or Debian, so you can own the whole stack
- +End-to-end encryption means the server stores only encrypted data and cannot read your documents
- +Real-time collaborative documents, spreadsheets, presentations, and shared drives in the browser
- +A free public instance (cryptpad.fr) lets you try it with no setup
- +Actively maintained by XWiki SAS with sustained public-interest funding
Trade-offs
- −It is a browser-based encrypted workspace, not a full desktop suite or a drop-in Microsoft-format editor
- −Compatibility with complex Microsoft documents is more limited than ONLYOFFICE or LibreOffice
- −The encryption model means account recovery and some integrations work differently from conventional suites
- −Self-hosting requires running a server, and encrypted real-time editing is heavier than plain document storage
