Like Framasoft? Not that I know of. There are local versions in Europe. A lot smaller is https://disroot.org from the Netherlands.

There are floss projects that are growing: - Nextcloud (German) - Mastodon (German) - Element/Matrix (UK and French) - Pixelfed (Canada) - Small Tech (Ireland)

There's also Codeberg https://join.codeberg.org/ (Germany)

Framasoft is a French association.

I heard about:

https://nlnet.nl/

"It spawned the world-renowned NLnet Labs, and supported great open source projects like Jitsi, ARPA2, WireGuard, NoScript, Tor Hidden Services, GPLv3, GNUnet, and webOD"

You could probably check the list of organizations supporting "Public Money - Public Code" campaign:
