Naxsi Nginx High performance WAF

Naxsi and ModSecurity are... very different. They have distinct (and largely incomparable) backgrounds, philosophies, goals, implementation details, and, most importantly for this context, vastly different DSLs that support their operations. A 1-1 translation of the OWASP CRS (particularly v3, just recently released) from ModSecurity's rule language to Naxsi rule syntax just isn't possible. ModSecurity provides a number of features that are either unsupported or impossible in Naxsi, and given that the CRS was written explicitly for ModSec, taking advantage of some implantation-specific features... well, good luck ;) (and at this point you might as well use libmodsecurity or an openresty alternative like lua-resty-waf, as Naxsi is probably never going to support the operators and feature sets needed for the CRS).
As for CFs rules, I'm not 100% sure, but that essentially sounds like asking for access to CFs internal data pipeline. I doubt you'll find a published version of this, as it's data that powers their commercial WAF.
