Process Lasso is free to use indefinitely, but some advanced features may disable over time and a nag may be shown. Process Lasso Pro unlocks everything, with a lifetime license that is a one-time payment. Commercial use requires a license within 30 days of deployment.
Every Pro feature can be tried during a short trial after you install. After the trial, the free version keeps every feature marked Yes below, and adding rules for features marked Trial only needs a Pro license.
