LyBox is a Firefox extension designed to streamline the real estate search process by integrating essential tools directly into popular property listing websites. It provides users with valuable insights such as gross and net yield calculations, cash flow analysis, and price trend assessments for specific areas and cities. This functionality is automatically activated on compatible real estate sites, enhancing the user experience without requiring any changes to their regular browsing habits.

Currently, LyBox is compatible with platforms like Leboncoin, SeLoger, Logic-immo, and AvendreAlouer, with plans for broader integration in the future. The extension features a convenient icon in the browser's upper right corner, ensuring users can easily verify its active status while browsing their favorite real estate listings.
