What are some great tech services made by europeans?

LibreOffice, Odoo, Mastodon, Nextcloud and more. Lots of Linux distros and desktops are based in Europe.

There is a lot of FOSS done in Europe and EU is very proactive with it. CERN is really helping open hardware and KiCAD.

The first I can think of (because I'm using them):

• Filen (E2E) encrypted cloud from Germany. Replaced my other cloud services for a few months now.
• Codeberg, for git stuff. I'm no dev (I just use it for my own little scripts) so I could not tell how feature-rich it is or if it lacks anything it is but so far it seems to be working great ;)
• Mullvad VPN, Swedish if I'm not mistaken.
• Should I also mention LibreOffice? It's not a European product, but its 'foundation' is German-based if I recall correctly.
• Hetzner a German company for cloud, webhosting and some other stuff I can't even begin to understand ;)

That said, I mostly focus on software being Free/Libre. Maybe in the coming years, with the rise shit nationalistic politics that we're witnessing, I will have to focus on EU-made products and services only—that would be sad.

Nextcloud is German, I think.

Controversial take, Spotify

Kolabnow for mail! Based in Switzerland, focused on privacy.

My friend uses zoner.cz for editing photos. The license is like 50€ and at least for us (we use it for editing photos for children group) they don't care about password sharing.

If you don't want or can't self-host, I can recommend Posteo for E-Mail, Calendar, Contacts and Filen.io for Cloud-Storage.

platform.io is Ukrainian so is Grammarly and GitLab and Reface and Restream
