TeamViewer is a proprietary remote desktop and remote access platform used widely for IT support and unattended device management, free for personal use with paid Remote Access, Business, Premium, Corporate, and Tensor subscription tiers for commercial use. Full details →

TeamViewer’s free tier is limited to personal, non-commercial use, and commercial licensing scales with the number of users, devices, and concurrent sessions. RustDesk offers a directly comparable client-server remote-access model under an open source license, with the option to self-host your own relay server instead of paying for named-user licensing. Remmina is a better fit if you mainly need to connect to machines that already run a standard RDP, VNC, or SSH server, since it’s a multi-protocol client rather than a full replacement for TeamViewer’s own client-server system.

Open Source Alternatives

RustDesk is an open source remote desktop application written in Rust, designed for self-hosting your own relay server as a free, auditable alternative to AnyDesk, NoMachine, and TeamViewer.

AGPL-3.0
