Collabora Online vs CryptPad
Both are free/open-source alternatives to Microsoft 365. Here's how they stack up — verified facts, no spin.
Collabora Online
Self-hosted, browser-based collaborative editing built on the LibreOffice engine.
Collabora Online is a self-hostable, browser-based office suite from Collabora that brings real-time co-authoring to the LibreOffice engine, so multiple people can edit the same Writer, Calc, or Impress document at once through a web browser. The free Collabora Online Development Edition (CODE) is a rolling release aimed at home use, testing, and small teams, while the supported Collabora Online product targets organizations that need stability and vendor support. It is the natural way to add Google-Docs-style collaboration on your own server, and it is what powers Nextcloud Office (the richdocuments app) inside a Nextcloud instance. It is MPL-2.0 licensed.
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.

| Collabora Online | CryptPad | |
|---|---|---|
| Sovereignty Score | 95 | 92 |
| Open source | Yes | Yes |
| Self-hostable | Yes | Yes |

| Pricing | Free self-hosted CODE edition; paid supported edition and hosting available | Free / self-host; free public instance at cryptpad.fr |
Collabora Online edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
Collabora Online
Strengths
- +Fully open-source under MPL-2.0, an OSI-approved license
- +Real-time, in-browser co-authoring of documents, spreadsheets, and presentations on a server you control
- +Built on the mature LibreOffice engine, so format handling matches LibreOffice closely
- +Powers Nextcloud Office, giving an easy path for people already running Nextcloud
- +Supports ODF and Microsoft formats, keeping documents portable
Trade-offs
- −Requires running a server; setup and maintenance are more involved than a desktop install
- −The free CODE edition is a rolling release the vendor does not recommend for production; production use points to the paid supported edition
- −Best used alongside a file backend such as Nextcloud, rather than as a standalone suite
- −Browser-based editing depends on the server being available, so it is less 'offline-first' than a desktop app
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
