About the URL Validator
This is a structural check: it parses each URL and reports what it found. No request is made, so a URL that is well-formed but dead still passes - nothing here tells you whether a page exists.
Not making requests is also what keeps this tool free of server-side request forgery risk.
Questions people ask
Is your code uploaded to a server?
No. This tool runs entirely in your browser using standard web APIs, so your code never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.
Is it free, and do I need an account?
Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
