Real use case example

"A founder wants to monitor their competitors' website for product changes and pricing updates. They use web-check to create an automation that scrapes their competitors' site for changes every night, then sends the findings to their team via Slack. After a week, they've got a comprehensive report of their competitor's site updates."

If you're senior

When to use it

•When researching competitors' websites to identify potential security vulnerabilities
•When performing due diligence on a potential partner or acquisition target
•When auditing your own website's security and infrastructure

Quick start

1Run the command 'npm install' to set up the required dependencies
2Configure your target website in the 'config.json' file
3Use the command 'node index.js [website_url]' to start the analysis
4Review the generated report to identify potential security issues and areas for improvement
5Use the '--help' flag to explore additional options and features, such as specifying custom headers or timeout values

Ready-to-paste prompt

Heads up: The tool requires Node.js (version 16 or higher) to be installed on your system, and some features may not work as expected if the target website uses advanced security measures such as CAPTCHAs or rate limiting
