Free website checkers
Each tool runs the full LaunchSafer audit and highlights the checks for that topic. No sign-up, results in 30–90 seconds.
Schema Markup Checker
Check which schema markup your pages use. LaunchSafer finds JSON-LD and microdata, lists the schema.org types and flags JSON-LD that won't parse.
Open tool →Mobile-Friendly Test
Test if your website is mobile-friendly: responsive viewport, pinch-zoom, mobile Lighthouse score and Core Web Vitals on a simulated phone.
Open tool →Robots.txt Checker
Check your robots.txt: whether it exists, how many rules apply to crawlers, whether it lists your sitemap, and whether pages are blocked or noindexed.
Open tool →XML Sitemap Checker
Check your XML sitemap: find it via robots.txt or /sitemap.xml, confirm it loads, count its URLs, and spot pages that are broken or not indexable.
Open tool →Meta Tag & Open Graph Checker
Check page titles, meta descriptions, canonicals and Open Graph tags across your site, with lengths, duplicates and missing tags flagged per page.
Open tool →Security Headers Checker
Check your website's security headers: HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, HTTPS and mixed content.
Open tool →Core Web Vitals Checker
Check your Core Web Vitals: LCP, CLS and INP from Google Lighthouse and real-user Chrome data, with the specific fixes that would improve them.
Open tool →Landing Page Analyzer
Analyze your landing page: headline clarity, call to action, social proof, form friction, mobile setup and load speed, each with evidence and a fix.
