Office suites cover documents, spreadsheets and presentations, and most cloud suites add email, file storage and real-time co-editing. Buyers in Europe look for vendors that keep files under European law, on European servers or on their own. The strongest European options are Nextcloud (Germany) for organisations that want to run the platform themselves, Infomaniak (Switzerland) for small businesses that want one Swiss provider and Proton (Switzerland) for teams that want encrypted email and files in one plan.

A company counts as European if it's headquartered in Europe: the EU, the EEA, Switzerland, the UK, or elsewhere in geographic Europe, never Russia or Belarus. Headquarters means where it's run from, not a registered office. Companies founded in Europe but headquartered elsewhere today are listed separately, and a non-European owner is always named.
Each company was checked against its own legal notice, pricing page and data-processing terms, and its G2 page. The order weighs how fully each one replaces the US leaders, its track record and its ratings. No company paid to be listed or ranked.
Nextcloud (Germany) for organisations that want to run the platform themselves, Infomaniak (Switzerland) for small businesses that want one Swiss provider and Proton (Switzerland) for teams that want encrypted email and files in one plan. Each is headquartered in Europe; the table compares their hosting, prices and G2 ratings.
Nextcloud, Infomaniak, Proton, Collabora Online, LibreOffice and CryptPad have a free plan with no time limit.
Infomaniak and Proton store customer data in Europe by default. Being European doesn't make a tool GDPR compliant on its own: check its data processing agreement too.
Yes: Nextcloud, Collabora Online, LibreOffice, CryptPad, Twake Workplace and openDesk, which you can also host on your own servers.
Yes. LibreOffice and SoftMaker Office are desktop suites from Germany that open and save Word, Excel and PowerPoint files. Collabora Online, built on LibreOffice, does the same in the browser. Complex layouts and macros can still look different, so test your own templates.
It is hard to say. Its developer lists a Singapore holding company first, with offices in Latvia, Armenia, Serbia, the UK and the US, so we can't tell where it is run from and leave it out. Euro-Office is a 2026 fork of its code backed by Nextcloud and IONOS.
Yes. Nextcloud, Collabora Online, CryptPad, Twake and openDesk are open source and can run on your own servers. Self-hosting means your team, or a hosting partner, handles updates, backups and security.
