FediMeteo is an international weather service running on a small €4 FreeBSD VPS, delivering weather updates to thousands of users on the Fediverse. The project, inspired by personal experiences, utilizes FreeBSD jails for efficient resource management and relies on open-source tools like Open-Meteo and wttr.in for weather data. Despite initial expectations of limited interest, FediMeteo gained widespread attention, expanding to cover 33 countries and over 2,600 cities. Its success highlights the potential of minimalist, efficient systems in creating impactful services. BSD users will appreciate the technical implementation, including the use of snac for low-resource management and the Unix philosophy in designing the system. The project also demonstrates the scalability of FreeBSD and snac, as the service continues to grow without significant performance issues.
