Plateforme Centres-sociaux.fr is a website creation and hosting platform provided by the Fédération des centres sociaux et socioculturels de France (FCSF) for its member social centres. The service helps these organisations build a professional online presence, with the platform handling hosting, security and maintenance while users manage their own website content. The service has supported social centres since 2011 and now hosts more than 500 sites.

Built on WordPress, the platform offers ready-to-use website themes, including options designed for social centres, as well as tools to customise layouts and content. Users can publish pages and articles, send newsletters, create forms and agendas, link social media accounts, and add other features through extensions. Support is available for beginners, experienced users, developers and agencies, with guidance, tutorials, assistance and demo sites to help them work at their own pace. Site activation is described as taking around 72 hours after a request. FCSF membership also connects centres with training, support, national partnerships and a wider network.
