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 allows users to suggest new locations or report inaccuracies, making it a community-driven tool. Its popularity surged in 2025, with nearly 20,000 users in one week during March, following France’s darkest winter in 30 years. The app aims to help Parisians find sunny spots in a city known for narrow streets and tall buildings, where terraces are culturally significant but have declined from several thousand in the 1970s–80s to just over 1,000 today. Experts note that rising rents and social changes threaten French bistrot culture. The app’s real-time sun mapping highlights the movement of sunlight across the city, assisting users in locating terraces bathed in sun, which are considered important social spaces in Paris.
