This is only a part of france’s “LaSuite” (very original name guys), that seemingly will replace every equivalent american service.

lasuite.numerique.gouv.fr

They generally work pretty well (demo on the site) and are a mix of homegrown solutions and rebrands of existing projects like matrix. All of them are open source.

Work with LaSuite

LaSuite brings all agents and professionals together in the public sphere

They should have called it “du coup” for that authentic frenchness.
