FreedomBox

FreedomBox is a Debian-based operating system designed to run on small hardware like a Raspberry Pi or an old laptop. It bundles a curated set of self-hosted applications so you can run your own email, chat, file sync, wiki, and more without relying on big tech servers. The system installs everything from a web interface and manages Let's Encrypt certificates, automatic updates, and security hardening out of the box.

The project supports a wide range of single-board computers and x86 hardware. It includes apps like Syncthing, Prosody XMPP, Radicale calendar, MediaGoblin, and Roundcube webmail. You manage everything through a web-based control panel called Plinth, which handles service setup, user accounts, DNS configuration, and backups. FreedomBox also integrates Tor and VPN support for privacy, and it can federate with other servers using protocols like XMPP and Matrix.

It's best suited for privacy-conscious individuals or small communities who want to own their data without managing a complex server. FreedomBox is free software (GPLv3), developed by the FreedomBox Foundation. You can install it yourself or buy pre-configured hardware from friendly vendors. The project has been around since 2010 and has one of the most approachable setups for a self-hosting newcomer.
