RealMarket Site Check

ChatGPT plugin

Check site email and security

View in ChatGPT directory

RealMarket Site Check helps developers and website maintainers diagnose public website configuration and prioritize technical fixes. Give it a website address to receive findings from public DNS records, pages and scripts.

  • Email and site security: check SPF, DKIM and DMARC records, mail servers, HTTPS and security headers.
  • Web app security: inspect public JavaScript for exposed API keys and public source maps, and check security headers, deployment freshness and error monitoring.
  • Shopify storefront diagnostics: check social login, wishlist, the share of sold-out products and storefronts in several countries. This check requires a Shopify store.

Each report includes a verdict, findings and suggested next steps. Email reports are in Portuguese; web app and storefront reports support Portuguese and Spanish. No account is needed. Checks only read public information: they never log in, submit forms or access private areas. A firewall can block a check, and the results are not a comprehensive security audit.
