A developer-friendly web scanning tool
Project description
🚀 ready is a tool for developers to check how production ready their website.
Usage
Install the tool from PyPI with:
pip install ready-check
Running the checks for a domain is as simple as:
ready <domain>
For more options, check the output of --help.
Usage during development
If you have cloned the repository and would like to run the checks with your local version, simply run:
python3 -m ready.ready <domain> [--request-filter=<x>] [--check-filter=<x>]
Optional Dependencies
There are no required dependencies, but two optional dependencies that enable some additional behaviour:
- Installing the
tldpackage adds support for using the fully-qualified domain name for some DNS-related checks. This is handy if you want to check a subdomain. - Installing
beautifulsoup4adds support for extracting some headers from the HTML document as well as the headers. This technique can be used for sites that use static hosting like Github Pages.
Note: if you install from PyPI these dependencies are installed.
