JAST v 0.4

Jast (Just Another Screenshot Tool) is a tool that can be used to automate the process for screenshots of webhosts. Jast uses the Selenium webdriver and the Firefox browser for image capture and writes all results to the specified output folder.


Jast requires Python>=3.4 in order to operate along with geckodriver>=0.23.0 and Firefox>=64.0.2.

Python-specific requirements can be found in the requirements.txt file.


To install Jast, it's recommended to setup a Pipenv shell in order to prevent the module installation from affecting yout other Python tools. This can be done via the follwing: $ pipenv shell

To install any requirements, once in the Pipenv shell run: $ pip install -r requirements.txt


Running Jast is relatively straightforward. Jast requires either a single URL or a list of hosts to screenshot along with a directory to write the report to. Hosts should be in the format http(s)://:. Hosts not in this format will generate an error message and will be skipped.

Single URL Example $ -u -o /path/for/report

Multiple Host File $ -f /path/to/hosts -o /path/for/report

Additionally, Jast supports a variety of flags to deal with common scenarios that may arise with webhosts, such as redirects. If you want to have Jast follow redirects before taking a screenshot supply the --follow-redirects flag.

Following Redirects $ -u -o /path/for/report --follow-redirects

If you want Jast to also document any headers that are sent from the webhost, use the --headers flag, and Jast will write all received headers below the captured screenshot.

Capturing Headers $ -u -o /path/for/report --headers

Finally, you can control the image size by passing a --size parameter to specify the size of the browser window. By default, Jast will use a window size of 800x600.

Changing Window Size $ -u http://www.exmaple/com -o /path/for/report --size=1024x768


Jast writes an HTML report in the specified output folder containing a report.html file and some associated style documents. All screenshots are saved in the /screenshots/ subfolder. The image below shows an example report that is created when scanning a multiple hosts using Jast and including the --headers flag:
