What it is

You use web-check to investigate and analyze any website.

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."

When to use it
  • β€’When researching competitors' websites to identify potential security vulnerabilities
  • β€’When performing due diligence on a potential partner or acquisition target
  • β€’When auditing your own website's security and infrastructure
Ready-to-paste prompt
node index.js https://example.com --headers="User-Agent: Mozilla/5.0" --timeout=30000
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
