CasaOS: An open-source home server OS for Docker apps

CasaOS is an open-source operating system for home servers, designed to make self-hosting easy for non-technical users. It provides a web-based interface to manage files, run Docker containers, and install apps like media servers (Plex), password managers (Bitwarden), or home automation (Home Assistant) without using the command line. It runs on low-power devices like Raspberry Pi or old PCs. The project was created by IceWhale Tech, a Chinese company, and competes with similar home-server platforms like Unraid, TrueNAS Scale, and Umbrel. CasaOS gained popularity as a free, lightweight alternative for users who want local control of their data instead of relying on cloud services.
