RWeverything is a freeware tool, no source available. It includes a Windows kernel driver. CHIPSEC can be configured to trust and use that driver. It has been many years since I’ve trusted third-party freeware where I didn’t know the third-party author or have many other knowledgeable friends who trust them.
