About CasaOS

CasaOS is a personal cloud system built for home use. It turns a small server, such as a Raspberry Pi or an old PC, into a private cloud where you store files and run apps without paying for a separate SaaS subscription for each one. The project is developed by IceWhale and released under the Apache-2.0 license.

The interface is designed for people who are not system administrators. Applications run as Docker containers that you can install and manage from the web dashboard, and the project's topics point to home automation, IoT and home-server use. The backend is written in Go with a Vue front end, and the README frames the product around data ownership and lower cloud costs for individuals and small organizations.
