Chrome Remote Desktop is an okay TeamViewer alternative, this free, open-source tool is better than both

RustDesk is presented as a superior free, open-source alternative to both Chrome Remote Desktop and TeamViewer. Built with Rust for lean performance, it offers lower latency, built-in file transfer with drag-and-drop, chat, cross-platform native apps (Windows, Mac, Linux, Android), and self-hosting support via Docker. A standout feature is the custom client builder, allowing branded remote desktop clients for tech support or small businesses. Setup requires no sign-up — just an ID and password — making it fast to deploy for personal or professional use.
