Gowitness - A Golang, Web Screenshot Utility Using Chrome Headless

gowitness is a website screenshot utility written in Golang, that uses Chrome Headless to generate screenshots of web interfaces using the command line. Both Linux and macOS is supported, with Windows support 'partially working'.
Inspiration for gowitness comes from Eyewitness. If you are looking for something with lots of extra features, be sure to check it out along with these other projects.

Installation
All you would need is an installation of the latest Google Chrome or Chromium and gowitness itself. gowitness can be downloaded using go get -u github.com/sensepost/gowitness or using the binaries available for download from the releases page.

Running using docker
To screenshot a page using docker, simply run the following command that would also pull the latest gowitness image:

docker run --rm -it -v $(pwd)/screenshots:/screenshots leonjza/gowitness:latest single --url=https://www.google.com

Keep in mind that a folder needs to be mounted into the container for gowitness to write your screenshots to, otherwise they will be lost when the container exits. The container is configured with the /screenshots/ directory as the working directory, so the above command mounts a local screenshots/ directory there.
If you want to read an nmap file, save it locally into a screenshots directory, and use it with:

docker run --rm -it -v $(pwd)/screenshots:/screenshots leonjza/gowitness:latest nmap -f /screenshots/nmap.xml

For any other commands, you can get help similar to the local binary install. For example:

docker run --rm -it -v $(pwd)/screenshots:/screenshots leonjza/gowitness:latest -h

This should result in a file being created called: https-www.google.com.png

Screenshot a cidr
$ gowitness scan --cidr 192.168.0.0/24 --threads 20
