NoMachine vs TeamViewer
Side-by-side comparison of features, pricing, ratings, and alternatives.
NoMachine is a remote access application that lets users connect to and control another computer over the internet or a local network, built around the company's proprietary NX protocol tuned for low-latency, high-definition remote sessions. Beyond basic screen sharing, it supports remote file transfer, printing, audio streaming, and terminal/shell access, and can run through a standard web browser as well as its native desktop and mobile clients. The product line spans a free non-commercial edition for personal use, a paid Personal Edition with support for individuals and small commercial use, and Enterprise products (Enterprise Desktop, Terminal Server, Cloud Server) aimed at organizations that need centralized deployment, unlimited concurrent connections, VPN access, and two-factor authentication. It is widely used for remote IT support, accessing home or lab machines while traveling, and enterprise virtual desktop delivery.
TeamViewer is a cross‑platform remote‑desktop solution that lets users connect to computers, smartphones, and servers for support, administration, and collaboration. It offers encrypted connections, file transfer, and session recording without requiring VPN or firewall changes. The service provides a free tier for personal use and paid subscriptions for businesses, adding features like multi‑user sessions, mass deployment, and advanced reporting. TeamViewer integrates with ticketing systems and supports mobile devices, making it a versatile tool for IT teams and remote workers.
