Pi-hole is a Linux network-level advertisement and Internet tracker blocking application which acts as a DNS sinkhole and optionally a DHCP server, intended for use on a private network. It is designed for use on embedded devices with network capability, such as the Raspberry Pi, but it can be used on other machines running Linux, including cloud implementations.

WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks, and was designed with the goals of ease of use, high speed performance, and low attack surface. It aims for better performance and more power-saving than the IPsec and OpenVPN tunneling protocols. I use this for access to my home network outside of being at home, and for access to #thetubes.

Nextcloud is a suite of client-server software for creating and using file hosting services. It is enterprise-ready with comprehensive support options. Free and open-source means that anyone is allowed to install and operate it on their own private server devices.
