Summary: Indeed, TeamViewer is one of the most popular remote desktop software, but it does take a toll on your pocket. In fact, it might not even completely suit your business. But you can always switch to open source TeamViewer alternatives, which are more cost effective, flexible, and user friendly.

With most businesses functioning remotely over the last few months, remote access support has become critical to stay connected with employees and customers.

This sudden surge in demand for remote access to desktops and other devices is well supported by the availability of many advanced remote access tools like TeamViewer.

TeamViewer provides functionalities for screen sharing, video calling, file sharing, and meeting recordings. However, this paid remote access solution is a bit expensive at $50 per month for someone getting it for the occasional use.

Why are People Searching for Open Source Alternatives to TeamViewer?

TeamViewer has been a resourceful tool for managing desktop servers remotely. TeamViewer’s easy installation, cross-platform support, and remote desktop support and collaboration functionalities have made it a preferred choice for many.

However, there are many businesses, and young professionals are looking for TeamViewer alternatives. What could be the reason? Along with the expensive monthly licensing model, TeamViewer also lags in relaying certain commands like CTRL Tab and Ctrl + Alt + Delete.

On the contrary, many open source TeamViewer alternatives are doing quite well in terms of user-friendly features and pricing (mostly free).
