parsero
Robots.txt audit tool
Platforms: Linux · Last verified September 6, 2026
Parsero is a free script written in Python which reads the Robots.txt file of a web server and looks at the Disallow entries. The Disallow entries tell the search engines what directories or files hosted on a web server mustn’t be indexed. For example, “Disallow: /portal/login” means that the content on www.example.com/portal/login it’s not allowed to be indexed by crawlers like Google, Bing, Yahoo… This is the way the administrator have to not share sensitive or private information with the search engines.
Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
