Entrechat is a French-language IRC chat and community platform inspired by the Wanadoo and Voilà chat services popular in the early days of the internet. Operating since 2003, it offers free, real-time conversations and says users can join without registering, choosing a nickname and chat rooms to get started. The site lists 109 themed rooms covering topics such as meeting people, games, music, cinema, French regions and age groups, with options for adult and younger users. Members can also create a free account to protect a nickname, personalize a profile and keep a friends list.

Beyond chat rooms, Entrechat provides community features and resources, including member profiles, friendship requests, regional chat, and guidance on chat etiquette and IRC commands. Its site also includes information about IriX, IRC services and bots, alongside a blog and help pages. Entrechat presents itself as a welcoming francophone community, available around the clock, for spontaneous online discussion and social connection.
