About SiteStatus Toolkit
Professional diagnostics for a faster, safer, and more reliable web.
SiteStatus Toolkit was built with a simple mission: to provide developers, system administrators, and website owners with the fastest and most accurate server-side diagnostic tools available for free.
Unlike many "is it down" checkers that rely on browser-side pings or third-party APIs (which can be blocked or inaccurate), our tools run directly from our optimized Node.js servers. This ensures you get a "clean" view of your website's availability and security, exactly as a visitor's browser would see it.
What Makes Us Different?
- Zero Dependencies: We don't rely on external APIs that could fail. We query DNS resolvers and perform TLS handshakes directly.
- Real-Time Results: Our tools are built for speed, aiming to deliver comprehensive reports in under 2 seconds.
- Professional Grade: From security header scores to certificate chain verification, we provide deep-dive data without the complexity.
- Privacy Focused: We don't require accounts and minimize data collection. Your diagnostic history stays in your own browser's local storage.
