Ok, “La Suite Numerique” turns up the result:

• https://github.com/suitenumerique
• https://lasuite.numerique.gouv.fr/

I was able to translate the main site with Firefox, but the docs aren’t translating. They have a language selection in the top right, but it doesn’t work. I guess it’s very focused on the French audience only for now.

It says they’re switching to “Visio”, but when I search that, I only get a “microsoft visio” product.
