A French app named Jveuxdusoleil, created by Jean-Charles Levenne in 2020, uses sun-positioning algorithms and building-height data from OpenStreetMap to identify sunny terraces in Paris. The app, designed to help users find sunlit spots on cafe terraces, has gained popularity this year, with nearly 20,000 users in one week in March following France's darkest winter in three decades. It is community-driven, allowing users to suggest new locations or report inaccuracies. Parisian terraces, once numbering several thousand in the 1970s–80s, have declined to just over 1,000 today, with experts warning that rising rents and social changes threaten this cultural tradition. Levenne developed the app to address the challenge of finding sunlight in a city with narrow streets and tall buildings, and he maintains the project without profit. The app’s real-time mapping of sunlit terraces supports the preservation of Paris’s terrace culture, described as the city’s “second living room.” (Updated 21 Aug 2025, 18:38 IST; source: link)
