Free security tools

Every tool runs entirely in your browser. Your data is never sent to any server — not ours, not anyone's.

100% private — zero data leaves your browser

Why these run in your browser

Every tool on this page is plain JavaScript executing on your own machine. Nothing you paste — a URL, a password, an email header, a token — is uploaded, logged or stored anywhere. You can confirm it yourself: open your browser's Network tab and run any tool on this page, and you will see that no request leaves it.

That design has a practical payoff beyond privacy. Because there is no server in the loop, these tools work on internal URLs, staging environments and intranet pages that a hosted scanner could never reach. There are no rate limits, no queue, and no account to create.

The trade-off is that they only inspect what you hand them. They cannot see the page you are actually on — which is exactly what the extension is for: the same class of checks, running automatically against every page you visit.

These tools check what you paste. The extension protects you everywhere.

PhishClean monitors every page you visit in real time — catching phishing pages, token leaks, and credential theft before they happen.
