Cross-platform remote desktop software that runs on your own servers, giving you full data control as a direct alternative to TeamViewer and AnyDesk.

RustDesk is a remote desktop tool built for teams and individuals who don't want their remote access traffic passing through someone else's infrastructure. It works on Windows, macOS, Linux, and Android, and it's designed as a direct replacement for tools like TeamViewer, AnyDesk, and Splashtop.
The core appeal is self-hosting. Instead of relying on a SaaS provider's servers, you run the relay and signaling infrastructure yourself. Your data stays on your own machines, which matters for regulatory compliance, security-conscious IT teams, and organizations in industries where data residency isn't optional.
Key capabilities include:
Deployment runs through Docker, and the setup is intentionally straightforward. The self-hosted server handles routing without exposing your sessions to third-party infrastructure.
RustDesk has 30 million+ client downloads and is actively used by IT support teams, sysadmins, and remote workers. With 113K+ GitHub stars, it's one of the most widely adopted projects in its category. The community spans 50,000+ members across forums and chat, and the codebase is maintained actively with regular releases.
For IT teams already running tools like JumpServer for privileged access management, RustDesk fits naturally alongside as the remote desktop layer they actually control.
