Pown.js is a security testing and exploitation toolkit built on top of Node.js and NPM. Unlike traditional security tools like Metasploits, Pown.js considers frameworks to be an anti-pattern. Therefore, each module in Pown is in fact a standalone NPM module allowing greater degree of reuse and flexibility. Creating new modules is a matter of publishing to NPM and tagging it with the correct tags. The rest is handled automatically.
