Veyon is software for classroom management and for monitoring and controlling computers in schools and other training environments. Teachers and IT administrators can view student screens, broadcast their own screen, take remote control of a workstation, distribute and collect files, open websites on student devices, send messages, lock workstations and manage logins and restarts. Veyon runs directly on the endpoints. Additional commercial add-ons cover, among other things, internet access control, device control, screen recording and synchronisation of users and devices with Microsoft 365 (Entra ID).
Veyon is developed by Veyon Solutions in Chemnitz, Germany, which says it has been active since 2004. The core is free and open-source software under the GPLv2; the optional add-ons are commercial. Veyon needs no cloud platform and can be deployed on the organisation's own infrastructure; no hosted service of its own is described. Only the optional Entra ID add-on connects to Microsoft 365, so schools that want to avoid that link can leave it out.
