README

webanalyze

This is a port of Wappalyzer in Go. This tool is designed to be performant and allows to test huge lists of hosts.

Because Wappalyzer removed the public access to their app definitions, webanalyze currently loads definitions from enthec.

Installation and usage

Precompiled releases

Precompiled releases can be downloaded directly here.

Build

If you want to build for yourself:

$ go install -v github.com/rverton/webanalyze/cmd/webanalyze@latest $ webanalyze -update # loads new technologies.json file from wappalyzer project $ webanalyze -h Usage of webanalyze: -apps string app definition file. (default "technologies.json") -crawl int links to follow from the root page (default 0) -host string single host to test -hosts string filename with hosts, one host per line. -output string output format (stdout|csv|json) (default "stdout") -search searches all urls with same base domain (i.e. example.com and sub.example.com) (default true) -silent avoid printing header (default false) -update update apps file -worker int number of worker (default 4)

The -update flags downloads a current version of technologies.json from the wappalyzer repository to the current folder.
