urlscan.io
Opens a suspicious URL in a sandbox and shows you everything the page loaded.
Submit a link and it visits the page from its own infrastructure, then reports a screenshot, the full request chain, every domain and IP contacted, the certificates, and the technologies detected. That is exactly what you want for a phishing link: you see the fake login page without ever loading it yourself. Public scans are searchable, which is also how researchers spot campaigns.
Questions
Works the moment the page loads. No account, no email, no trial. Anonymous submissions default to public, so a link containing a token or a personal identifier becomes searchable by anyone.
Yes. urlscan.io sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
