MonSite

MonSite crawls your website from top to bottom and shows its health in a single report: links, performance, accessibility, SEO, security and SSL. Type the address, start the scan, and MonSite does the rest.

BROKEN LINKS AND RESOURCES • Opens every page on the site and finds 404s and server errors • Lists images, scripts, CSS, fonts and files that fail to load • Catches corrupt images and addresses that return an error page instead • Checks whether external links still work • Reads sitemap and robots.txt, and checks fonts and images referenced in CSS

PERFORMANCE • DNS, connect, TLS, time-to-first-byte and download times for every page • Slowest pages and slowest-loading resources • Compression, caching, HTTP/2 and render-blocking scripts • Oversized images and page weight

ACCESSIBILITY (WCAG) • Images without alt text, links and buttons without names • Unlabeled form fields, page language, heading structure • Disabled zoom, untitled iframes and more

SEO • Title and meta description checks, duplicate titles • Canonical, noindex, mobile viewport, social preview tags • Sitemap, robots.txt, orphan pages and soft 404s

SECURITY • HTTPS usage and HTTP-to-HTTPS redirects • Security headers such as HSTS, CSP and clickjacking protection • Cookie flags, mixed content and forms submitted over plain HTTP • CSP and HSTS quality, Subresource Integrity for external scripts • Server version disclosure, security.txt • Optional: publicly exposed .git, .env and backup files

SSL CERTIFICATE • Trust status, issuer, start and expiry dates • Days remaining, with a warning as expiry approaches • Key type and size

HEALTH SCORE • An overall score and A–F grade, plus a separate score for each of five areas • Issues grouped by severity and category

SCHEDULED MONITORING • Monitor your sites every minute, hour or day • Every check is compared with the previous one: new and resolved issues, newly broken and fixed resources, slower pages, certificate renewals • Uptime percentage, average response time and last downtime • Detects downtime when expected text is missing from the home page • Notifications when something changes • Trend charts for score, load time and issue count

PRIVACY MonSite collects no personal data. No account, no ads, no tracking. All results are stored only on your device.

Share reports as text or JSON.

Note: iOS decides when background checks run; while the app is open, checks run at the interval you choose. Only scan sites you own or are authorized to test.
