Crossfyre vs Nuclei
A template-based vulnerability scanner vs a distributed recon-to-authz pipeline.
Nuclei (by ProjectDiscovery) is a fast, free, template-driven scanner for checking known issues, and Crossfyre stays compatible with its templates. But Crossfyre is a wider layer: the distributed recon that maps your attack surface, then its own from-scratch engine (cortex) that confirms every finding by reproducing it before reporting, plus active injection fuzzing and API authorization testing (BOLA/BFLA/BOPLA) that templates do not cover. You get the template corpus and a confirm-before-report pipeline, without wiring five tools together.
Feature by feature
| Feature |  Nuclei | Crossfyre |
|---|---|---|
| Template library | Large community corpus | Nuclei-compatible, plus a curated pack |
| Recon built in | no | yes |
| Confirms a finding before reporting it | Reports what matched | Reproduces it first |
| Authorization testing (BOLA, BFLA, BOPLA) | no | yes |
| Distribution and scheduling | Yours to build | Built in |
| Dashboard, history, exports | Yours to build | Built in |

Standards
What it covers, and what it will not claim.
Pick a list. Every row that says yes names the class that does the work, and every row that says no says why, because a coverage matrix with no gaps in it is a brochure.
8 covered 1 partly 1 not claimed The list this engine was built against. Eight fully, one partly, and one that nothing on the outside can honestly report.
MITRE ATT&CK is deliberately not here. It describes what an adversary does across a whole intrusion, and almost all of a web scanner collapses into one technique in it. A six-row ATT&CK matrix would look impressive and tell you nothing, which is the opposite of what this section is for.
The honest take
If all you want is a templated scanner, Nuclei is great and free, and Crossfyre runs its templates too. Choose Crossfyre when you want the distributed recon around your scanning plus a confirm-before-report engine and authorization testing that a template runner does not provide.
Questions people ask
Does Crossfyre do vulnerability scanning like Nuclei?
Yes, and more. cortex is a from-scratch engine that stays Nuclei-template compatible but adds active injection fuzzing and a non-bypassable confirm-before-report pipeline (every finding is reproduced before it is emitted). It also runs API authorization testing (BOLA/BFLA/BOPLA), which templates do not cover. The curated pack is newer and smaller than Nuclei's corpus; the discipline and the authz engine are the difference.
Can I use my Nuclei templates with Crossfyre?
A supported subset works as-is: matchers, status/word/regex/dsl conditions, and payload fuzzing. cortex also ships its own built-ins that always run and a curated starter pack, so you are not starting from an empty engine.
