About
That link in your messages. Check it without leaving the app.
Share any link straight to SecURL and see where it really leads, right there: the full redirect path, the final destination, and whether it is protected by HTTPS. You never open the page, and you never leave the conversation you are in. Or scan a QR code from a poster, menu or message, and see the truth in seconds. Nothing is opened, downloaded, or run.
It's honest, too: SecURL tells you what looks fine and what deserves a closer look, and it never claims a link is "safe". It shows you the evidence and lets you decide.
CHECK IT WHERE YOU FOUND IT
• Share a link from Messages, Mail, a browser or any other app
• On iPhone the result appears right in the share sheet, without switching apps
• On Android SecURL opens straight to the link, ready to check
• No copying, no pasting, no hunting for a website to paste it into
CHECK A LINK OR QR CODE
• Scan a QR code, or paste any link
• See the real final destination and every redirect along the way
• Know if a link starts without HTTPS, drops HTTPS, or quietly changes site
• A passive check: the page is never opened, no scripts run, nothing is downloaded
GRADE ANY WEBSITE, A TO F
Want a deeper read on a site? SecURL scans its external security posture and gives it a letter grade from A to F, with a clear breakdown: HTTP security headers, TLS configuration, certificate health, DNS and domain signals, and the third-party services it exposes. Every finding comes with a plain-language explanation and what to do about it.
WATCH THE SITES YOU CARE ABOUT
Add any site to your Monitor and SecURL keeps an eye on it for you: posture drops, security-header changes, and certificate expiry, renewal or issuer changes, and alerts you when something moves. Never get caught out by an expired certificate or a silent downgrade again.
PRIVATE BY DESIGN
No account. No login. No tracking. Everything is a passive public check; the only thing that leaves your device is the link or site you choose to check. SecURL queries no malware or blocklist databases, so it stays honest about what it can and can't tell you. "No obvious concern" is never a promise a link is safe.
Whether you're wondering if a link in a message is a scam, or a developer checking a deployment before release, SecURL gives you a fast, honest read, before you trust it.

What's New in SecURL
1.6.0
September 17, 2026
SecURL now opens straight to Check a Link, so the thing you came for is the first thing you see. We also stopped asking for notification permission the moment you install. SecURL only asks when you start monitoring a site, which is the only time alerts are useful. Fixes: the QR scanner's aiming guide and results now sit properly over the camera, a crash when a site had no grade yet is gone, and background monitoring requests are more reliable.
