QLab 4 Features by License Type

QLab 4 is a free program, with additional optional features that can be unlocked by purchasing and installing a license. This chart shows which of the major features are enabled by each type of license.

Most of the advanced features can be used experimentally without a license installed, and will only require the license if you re-open a saved workspace that uses these features.

For those features which cannot be tested in this way, QLab has a demo mode which enables all features for twenty minutes. While demo mode is active, all of QLab’s licensed features are available, but saving, copying, and pasting are disabled. All workspaces will automatically close after 20 minutes. Demo mode will exit when you quit QLab.

To activate demo mode, choose Start Demo Mode… from the QLab menu.
