Web-Check is a powerful, open-source tool designed to provide comprehensive insights into a website’s underlying structure, security, and performance.
Developed by Alicia Sykes, it is available for free use and modification under the MIT license.
This tool is particularly useful for developers, system administrators, security researchers, and anyone interested in understanding the inner workings of websites.
Core Features Of Web-Check
Web-Check offers a wide array of features that help users analyze and optimize websites:
- IP Info and Server Location: Provides the IP address associated with a domain and identifies the server’s physical location, aiding in understanding network infrastructure and potential latency issues.
- SSL Chain and TLS Configuration: Analyzes SSL certificates and TLS configurations to ensure secure data transmission and identify potential vulnerabilities.
- DNS Records and Security Extensions: Examines DNS records (A, MX, NS, CNAME, TXT) and DNS security extensions like DNSSEC, which protect against DNS spoofing.
- Cookies and HTTP Headers: Inspects cookies for tracking and session management insights and analyzes HTTP headers for server configurations and security policies.
- Crawl Rules and Site Performance: Checks robots.txt files for SEO strategies and uses Lighthouse to assess performance, accessibility, and SEO metrics.
- Associated Hostnames and Redirect Chain: Identifies associated domains and analyzes redirect chains for potential security risks.
- Open Ports and Traceroute: Scans open ports to identify running services and uses traceroute to map network paths.
- Carbon Footprint and Server Info: Estimates the environmental impact of a website and retrieves server details like hosting providers and server types.
- Whois Lookup and DNS Security: Retrieves Whois records for domain ownership insights and checks DNS security measures.
- Tech Stack and Security Features: Identifies technologies used by a website and evaluates security features like HTTP Strict Transport Security (HSTS) and Content Security Policy (CSP).
Web-Check can be deployed via several methods, including Netlify, Vercel, Docker, or by building from source.
It supports optional environmental variables for enhanced functionality, such as API keys for Google Cloud, Shodan, and WhoAPI.
These keys can be set in an .env
file or through deployment platforms.
Web-Check is a versatile tool that simplifies the process of gathering and interpreting website data.
Its extensive feature set makes it invaluable for both technical and non-technical users seeking to understand, optimize, and secure websites.
With its open-source nature and ease of deployment, Web-Check is a valuable addition to any web development or security toolkit.
