websocket.org

We performed a comprehensive analysis of websocket.org on 2026-06-29. The website returned an HTTP 200 status code with a server response time of 11249ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 54 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Let's Encrypt (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_128_GCM_SHA256 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 1 domain(s) (Subject Alternative Names) and expires on 2026-08-05, which is 37 days from now. The security headers analysis reveals a score of 20/100 (poor). The following security headers are properly configured: Strict-Transport-Security (HSTS). However, the site is missing Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy, which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 3 technologies across 3 categories powering websocket.org. The detected stack includes React, Google Analytics 4, and Cloudflare. The UI is built with React. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, websocket.org receives an overall trust score of 66/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, websocket.org receives a trust score of 66/100, which places it in the "Likely Safe" category. This score is calculated by evaluating multiple factors including SSL certificate validity, domain registration history, email authentication protocols, security header configuration, and blacklist status across major threat intelligence databases. The analysis identified several positive trust signals: a valid HTTPS connection protecting data in transit, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, a valid SSL certificate issued by Let's Encrypt with 37 days until expiration, and DNSSEC providing authenticated DNS responses. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), missing Referrer-Policy, potentially leaking URL information to third parties, and the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked websocket.org against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal. The domain passed all 8 checks with a clean status, meaning it has not been flagged for phishing, malware distribution, spam, or other malicious activities by any of the tested threat intelligence providers.

Our technology detection engine scanned websocket.org and identified 3 distinct technologies across 3 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. UI Library: React — handles the user interface rendering and component management for websocket.org. Analytics: Google Analytics 4 — tracks visitor behavior and provides traffic insights for websocket.org. CDN: Cloudflare — accelerates content delivery by caching assets at edge locations worldwide for websocket.org. We also extracted the following tracking identifiers: Google Analytics 4 Measurement ID G-BZ0LYEZXEJ. These IDs can be used to identify other websites operated by the same organization.

websocket.org delivers its homepage in 11249ms (server response time), which is considered slow by industry standards. The total page weight is 54 KB, and we detected 63 resource requests loading assets from 3 third-party domains. A high number of third-party domains can significantly impact page load time due to additional DNS lookups and TLS handshakes required for each domain. The website uses Gzip compression for text-based assets, achieving an estimated 60.0% reduction in transfer size. This reduces bandwidth usage and improves page load times, especially for visitors on slower connections. Asset minification status: 0 out of 1 CSS files and 0 out of 2 JavaScript files are minified. Minifying the remaining 3 unminified file(s) could further reduce page weight by 10-30% for those assets. Minification is a best practice that reduces download sizes without affecting functionality. From an environmental perspective, each page view of websocket.org produces approximately 0.03g of CO₂, earning a carbon rating of A. This places the website among the cleanest on the web, demonstrating efficient use of server resources and optimized content delivery. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 54 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for websocket.org. This typically means the site doesn't have enough real-world Chrome user traffic to generate statistically significant field data, or the domain is not included in the CrUX dataset. Core Web Vitals (LCP, INP, CLS) are important Google ranking factors that measure real user experience.

websocket.org resolves to the IPv4 address 76.76.21.21, but does not support IPv6. IPv6 adoption is increasingly important as IPv4 address space becomes exhausted, and some ISPs and regions are transitioning to IPv6-only connectivity. The domain has 1 A record(s) configured. The domain name system is managed by 2 name servers: erin.ns.cloudflare.com and max.ns.cloudflare.com. Having 2 name servers provides good redundancy — if one fails, the others can continue serving DNS queries. The choice of name servers often indicates the DNS hosting provider or CDN service being used. SPF is not configured, meaning any server could potentially send emails pretending to be from this domain. This is a significant email security concern. DMARC is not configured, leaving the domain vulnerable to email spoofing and phishing attacks that impersonate this domain. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is enabled for websocket.org, providing an additional layer of security by cryptographically signing DNS records. This prevents DNS cache poisoning and man-in-the-middle attacks that could redirect visitors to malicious websites.

The homepage of websocket.org contains 878 words of visible text content. This is a moderate amount of content. The page is structured with 7 H2 headings, 11 H3 headings, 0 H4 headings. The link structure consists of 55 internal links pointing to other pages on the same domain and 4 external links pointing to third-party websites. There are 2 external JavaScript files, 1 CSS stylesheets, and 0 iframes on the page. The site implements the following web standards and features: robots.txt (controls search engine crawling behavior) and Schema.org structured data (Answer, FAQPage, Question, and WebSite). Notable missing features: XML Sitemap. Adding these could improve search engine discoverability and rich result eligibility. The website has social media presence across 1 platforms: Github (@mattheworiordan). An active social media presence is a positive trust indicator and helps build brand awareness and customer engagement.

The title tag for websocket.org is well-optimized at 51 characters: "WebSocket.org — The independent WebSocket reference". The length falls within the ideal range for Google search results, ensuring the full title is displayed without truncation. The meta description is 176 characters (slightly long): "The independent, practitioner-built reference for WebSocket technology. Protocol internals, production patterns, scaling...". Google typically displays up to 155-160 characters of the meta description in search results. A compelling meta description with a clear call-to-action can significantly improve click-through rates from search results. The page language is declared as en and a favicon is configured. Open Graph meta tags are configured with 4/4 recommended fields: OG title ("WebSocket.org — The independent WebSocket reference..."), OG description, OG image (social sharing thumbnail), OG type (website). These tags control how the page appears when shared on Facebook, LinkedIn, and other social media platforms that support the Open Graph protocol. A Twitter Card of type summary_large_image is configured, which controls how links appear when shared on Twitter/X. The "summary_large_image" type displays a large image preview, which typically generates higher engagement rates than the basic card type. The site implements Schema.org structured data with the following types: Answer, FAQPage, Question, and WebSite. Structured data helps search engines understand the page content and can enable rich results (featured snippets, knowledge panels, star ratings) in Google search results, which can significantly increase click-through rates.
