Web Scanner
Find broken links and security gaps before your visitors do.
Web Scanner crawls your site from the browser, checks every internal and external link, and reviews the security basics: headers, cookies, CSP, mixed content, SPF and DMARC, exposed files.
Passive checks only. Nothing you scan is sent to us.
What it checks
Two scanners in one panel, built for people who maintain websites.
Dead links
Crawls the pages of your site and checks every internal and external link once. Redirects show their full chain, hop by hop.
Where it broke
Every broken link lists each page it is on and its link text. Open the page and the link is outlined for you.
A security grade
HTTPS, security headers, cookies and exposed files, graded and sorted into what to fix first and smaller risks, in plain words.
Cookies and storage
Missing Secure, HttpOnly and SameSite flags, and sensitive-looking keys in browser storage.
Email spoofing
SPF and DMARC records of your domain, with the policy they actually enforce.
The fix for your server
Evidence, why it matters and ready-to-paste config for Nginx, Apache, Cloudflare, Next.js, Express and more, picked from what your site runs.

Questions
Does it attack or stress the sites I scan?
No. It sends ordinary requests, the same a browser sends when you open a page, with a configurable concurrency limit and delay. It never sends exploit payloads.
What happens to my data?
Results stay in your browser. The extension talks to the sites you scan, to Cloudflare's public DNS for SPF and DMARC lookups, and to Lemon Squeezy for license checks. Details are in the privacy policy.
How do I activate Pro?
After checkout you receive a license key by email. Open the extension, choose Get Pro, then I have a key, and paste it. One license works on up to 5 browsers.
Can I get a refund?
Yes, within 14 days of purchase. Reply to your receipt email.
