DeskPilot
Compatibility check
This checks whether your school device and network can run a workspace. It is free, it does not need an account, and it never asks for a password.
One thing this test cannot tell you
It checks your device and network only. It cannot tell you whether your school allows signing in to its systems from a cloud browser — some schools require a managed device. You must check that yourself, and you should never enter school credentials anywhere except inside the workspace with private login mode switched on.
