• Summary: Euro-Office is a FOSS office suite and collaboration platform (documents, spreadsheets, presentations, PDF) launched in March 2026 and reaching its first stable release on 9 June 2026. It is a fork of OnlyOffice, maintained by a consortium of European companies (IONOS, Nextcloud, Proton, OpenProject, XWiki, Soverin, Abilian, bTactic and others) with the goal of digital sovereignty — i.e. an office stack under European control and jurisdiction. Like OnlyOffice it runs as a web-based Document Server that connects to a host platform; the official integration today is the eurooffice-nextcloud connector. A Cloudron package of the Document Server (mirroring the existing OnlyOffice/Collabora packages) would let Cloudron Nextcloud users select Euro-Office as a Nextcloud Office backend.

---

• Notes: I'd like this because it's a drop-in-style alternative to the OnlyOffice Document Server we already have packaged, and it targets the same Nextcloud integration path — so it should map well onto Cloudron's existing OnlyOffice packaging pattern (separate document-server app + Nextcloud connector app, JWT secret, reachable both ways). Concerns / things to verify: (1) it's a young fork — first stable is literally days old, so expect rapid version churn; (2) the project is hosted on GitHub (Microsoft-owned), which some find ironic given the "sovereignty" framing; (3) being an OnlyOffice fork, it likely inherits OnlyOffice's resource footprint (CPU/RAM during conversions).

Isn’t this a duplicate ? Or it’s an original very close to something else

@timconsidine yeah, was discussed previously, but no one had created an App Wishlist post for it

[timconsidine]

@jdaviescoates oh, yes, rather good point !

[fbartels]

I created a community app for it https://ca.cloudron.io/app/euro-office

Attention: I have made a few tweaks to my release pipeline and as a result of that the url of the CloudronVersions.json has changed. The shop listing has the updated url, but I don´t think there is an automated upgrade so the app needs to be removed and reinstalled.
