RustDesk is a free, open-source remote desktop tool you can host yourself. It supports remote control, file transfer, TCP tunneling, and cross-platform access without relying entirely on proprietary remote desktop services.

It’s simple to use, supports self-hosted relay servers, and gives you more control over your remote connections and data.
