NOTE: NetLimiter 4 Pro vs. Lite licenses

Some users pointed out that we offer NetLimiter 4 Pro and Lite licenses in our shop but there is no list of features of these two products. So what are the differences? The truth is, that we don't know, yet.

We offer NetLimiter 4 Lite mainly for those users who would like to upgrade from NetLimiter 3 Lite. We still haven't decided which features will be included in NetLimiter 4 Lite, but we can promise that you will find there not less than in NetLimiter 3 Lite.

If you purchase NetLimiter 4 Lite now, you will be allowed to use the full-featured version (the Pro) until we release the Lite.
