appblock.app

We performed a comprehensive analysis of appblock.app on 2026-06-30. The website returned an HTTP 200 status code with a server response time of 9057ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 170 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_256_GCM_SHA384 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 5 domain(s) (Subject Alternative Names) and expires on 2026-09-06, which is 68 days from now. The security headers analysis reveals a score of 15/100 (poor). The following security headers are properly configured: X-Content-Type-Options. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-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 6 technologies across 6 categories powering appblock.app. The detected stack includes WordPress, Vite, Google Tag Manager, Google Fonts, jQuery, and WP Rocket. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, appblock.app receives an overall trust score of 68/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, appblock.app receives a trust score of 68/100, 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, a valid SSL certificate issued by Let's Encrypt with 68 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a none policy, DNSSEC providing authenticated DNS responses, and a well-established domain registered for over 8.2 years, indicating long-term commitment and legitimacy. 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 appblock.app 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. The domain is registered through Gransy s.r.o. d/b/a subreg.cz based in CZ, with a registration date of 2018-05-11 and expiration date of 2033-05-11.

Our technology detection engine scanned appblock.app and identified 6 distinct technologies across 6 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. CMS: WordPress — manages the content and page structure for appblock.app. Build Tool: Vite — bundles and optimizes the JavaScript and CSS assets for appblock.app. Tag Manager: Google Tag Manager — manages marketing and analytics tags without code changes for appblock.app. Fonts: Google Fonts — delivers web fonts for typography for appblock.app. JavaScript Library: jQuery — provides utility functions and DOM manipulation for appblock.app. Performance: WP Rocket — optimizes page loading speed and performance for appblock.app. We also extracted the following tracking identifiers: Google Tag Manager container GTM-MNKWWWW. These IDs can be used to identify other websites operated by the same organization.

appblock.app delivers its homepage in 9057ms (server response time), which is considered slow by industry standards. The total page weight is 170 KB, and we detected 223 resource requests loading assets from 15 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: 2 out of 4 CSS files and 6 out of 9 JavaScript files are minified. Minifying the remaining 5 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 appblock.app produces approximately 0.08g 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 170 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for appblock.app. 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.

appblock.app resolves to the IPv4 address 37.235.104.64 and also supports IPv6 (2a01:28:ca:112::1:105), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 3 name servers: ns.vas-hosting.com, ns.vas-hosting.cz, and ns.vas-hosting.eu. Having 3 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. Email for appblock.app is handled by Google Workspace with 4 MX records configured: alt2.aspmx.l.google.com, alt3.aspmx.l.google.com, and alt4.aspmx.l.google.com and 1 more. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF (Sender Policy Framework) is configured, which specifies which mail servers are authorized to send email on behalf of this domain. This helps prevent email spoofing and improves email deliverability. DMARC (Domain-based Message Authentication, Reporting and Conformance) is configured with a none policy — a monitoring-only setting that doesn't enforce any action on unauthorized emails. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is enabled for appblock.app, 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 domain is registered through Gransy s.r.o. d/b/a subreg.cz (CZ). It was first registered on 2018-05-11 and is set to expire on 2033-05-11, making it 8.2 years old. Our subdomain enumeration scan discovered 10 active subdomains for appblock.app: admin.appblock.app, api.appblock.app, app.appblock.app, blog.appblock.app, cdn.appblock.app, dev.appblock.app, m.appblock.app, and mail.appblock.app. Plus 2 additional subdomains. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The homepage of appblock.app contains 841 words of visible text content. This is a moderate amount of content. The page is structured with 9 H2 headings, 6 H3 headings, 0 H4 headings. The page includes 86 images. 12 images (14%) are missing alt text attributes, which is a significant concern for both accessibility and SEO. Screen readers rely on alt text to describe images to visually impaired users, and search engines use alt text to understand image content. Only 86% of images have proper alt text — we recommend adding descriptive alt attributes to all images.
