If you embed OpenLiteSpeed in your software and make changes to it, and are willing to contribute back your changes, you can use it with the LiteSpeed brand name on it, as our license is GPLv3.
For distributing the software, you do not need an OEM license.
If you want to sell it with your commercial products, please open a ticket to tell us what your estimated revenue generated is.
We have tiered pricing for OEM licenses.
