Parsero is a free and open-source tool available on GitHub.  Parsero is used to reading Robots.txt files of websites and web apps. This tool can be used to get information about our target(domain). We can target any domain using Parsero. It has an interactive console that provides a number of helpful features, such as command completion and contextual help. This tool is written in python, so you must have python installed in your Kali Linux to use this tool.

 It is a python script that is used to read Robots.txt file on a live web server in the disallowed entries. When the tool starts working, these disallowed entries tell the search engines what HTML files or static directories must or must not be indexed. Google spiders and crawlers play important roles in indexing a website according to the number of visitors. It is the responsibility of the administrator that they don’t share private and sensitive information with the search engines. But sometimes these developers mistakenly allow search engines to access Robots.txt file. Parsero helps in such situations by checking whether the Robots.txt file is visible or not.
