About SiteGraph

The Internet Intelligence Platform — making the web transparent, one scan at a time.

Our Mission

The internet is vast, complex, and often opaque. Website owners, developers, SEO professionals, and security researchers all need fast, reliable answers about how websites are built, where they run, and how they perform. SiteGraph exists to make this intelligence accessible to everyone — for free, in real time, and at scale.

We scan and analyze millions of websites, extracting technology stacks, hosting providers, CDN configurations, DNS records, TLS certificates, security headers, SEO metadata, performance metrics, accessibility issues, and much more. Every result is presented in a clear, actionable report that helps you understand any website in seconds.

Security Assessment

Check TLS/SSL certificates, HTTP security headers, and cookie configurations to assess a site's security posture.

Hosting & Infrastructure

Discover hosting providers, CDN networks, IP addresses, ASN information, and DNS records.

Knowledge Graph

3
Comprehensive report
Results are displayed in a structured report covering SEO, security, performance, accessibility, hosting, and technology stack — with scores, explanations, and actionable recommendations.
4
Explore & compare
Browse our index of millions of scanned websites, filter by technology, hosting provider, country, or security header, and compare technologies head-to-head.

Our Expertise

SiteGraph is built by AnantaHQ, a software engineering collective with deep expertise in web technologies, infrastructure, security, and data engineering. Our team combines years of experience in:

Full-stack engineering and cloud infrastructure

Our technology detection engine identifies hundreds of web technologies across categories including JavaScript frameworks, CSS libraries, CMS platforms, analytics tools, CDN providers, hosting platforms, and more — using a combination of HTTP header analysis, HTML parsing, JavaScript signature detection, and DNS inspection.

Data & Privacy

SiteGraph analyzes publicly accessible websites using the same information that any browser or web crawler would receive. We do not access private or authenticated content. Our analysis is limited to:

Publicly served HTTP responses and headers

Public TLS certificate data
Publicly listed ASN and IP geolocation data

We respect robots.txt directives and website terms of service. If you would like your website removed from our index, please contact us.
