What free analogue of TeamViewer can you recommend for a budget educational institution?

Question

open source

TeamViewer is a good program and completely satisfied in terms of the ability to manage computers in an institution, but the problem is that it is free only for home use. As I understand it, budgetary educational institutions such as schools and lyceums cannot freely use its capabilities. Therefore, there is a need to search for affordable analogues that are implemented on the principle of Open Source or another free license for this type of institution.

Answer 1

VNC

But if there is an antivirus on the computer, it will not let you into the site (I don't know the reason).

Answer 3

Depends on what program features are needed. Look towards iTALC and X2Go.

Answer 4

UltraVNC in conjunction with bginfo will solve your problem.
