Process Lasso

What is the Pro version? How free is free?

We don't want there to be ANY surprises with Process Lasso. We offer a free build of Process Lasso, and a paid/registered build called Process Lasso Pro. The free build becomes the Pro build after it is activated using a special code that can be purchased online from us. Home users can use the free build indefinitely, though they will eventually experience some nags and a reduction in available features (see chart below). Notice that the most popular features remain enabled indefinitely. Server Edition users have 30 days to fully evaluate the product before it expires. Process Lasso Pro is well worth the cost and your purchase helps support continued development. Process Lasso was the FIRST utility of its kind, and we'll keep breaking new ground with your support.

Over time, a solicitation (nag) may be displayed when the GUI starts, or when its main window is opened.

  • After a few days, a message is shown at startup.
  • After a few days, a message is sometimes shown when you open Process Lasso from the system tray.
  • After 7 days, advanced features (shown below) are disabled.
  • NEVER do we bundle with toolbars or other crudware with our installers!

Process Lasso PRO (the purchased version) offers extended features and special optimizations. It is up to you whether you want to invest in it or not. We hope you do. Please consider that without purchases we can not continue to work on Process Lasso or any other projects. Support a small business, get value for it, and become a Bitsum customer for life! Either way, we thank you for using our software.
