def more known for Artifactory (and community spin-offs like Conan and JFrog Container Registry), but CI/CD has become the core growth as the artifact storage is pretty robust at this point
NuGet is "one" of the packages that Artifactory can host (in addition to NPM, RPM, Python, etc etc etc)
You can also have unlimited private repos, and unlimited cache repositories for proxying public repos
I think the big part that everyoen missed, is that other than artifact storage (artifacts are usually what your code becomes, like the usable end product, and also stores info to reproduce and audit, etc etc) is that JFrog is also putting lots of efforts into full fledged software distribution pipelines, which is what these big enterprises need.
There is also the whole DevSecOps sections of their product, and though OSS is not as big, they are giving out plenty back to the community by hosting ChartCenter (Helm), GoCenter (Go-lang), JCenter (Java), and Conan (C/C++)
