reuse.software

We performed a comprehensive analysis of reuse.software on 2026-07-04. The website returned an HTTP 200 status code with a server response time of 21821ms. The page is served over HTTP/2 protocol, however no compression (Gzip or Brotli) is enabled, which means the page is transferred at its full uncompressed size. The total page weight is 12 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 ECDSA-SHA384 signature algorithm. The certificate covers 1 domain(s) (Subject Alternative Names) and expires on 2026-08-04, which is 31 days from now. The security headers analysis reveals a score of 15/100 (poor). The following security headers are properly configured: X-Frame-Options. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), 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 reuse.software. The detected stack includes Bootstrap, jQuery, and Font Awesome. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, reuse.software receives an overall trust score of 60/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, reuse.software receives a trust score of 60/100, 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 and a valid SSL certificate issued by Let's Encrypt with 31 days until expiration. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, missing Referrer-Policy, potentially leaking URL information to third parties, the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity, and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked reuse.software 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 reuse.software 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. CSS Framework: Bootstrap — provides the styling and responsive layout system for reuse.software. JavaScript Library: jQuery — provides utility functions and DOM manipulation for reuse.software. Icon Set: Font Awesome — provides additional functionality for reuse.software.

reuse.software delivers its homepage in 21821ms (server response time), which is considered slow by industry standards. The total page weight is 12 KB, and we detected 49 resource requests loading assets from 8 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. No compression is currently enabled on reuse.software. Enabling Brotli or Gzip compression could reduce page size by 60-80% for text-based assets (HTML, CSS, JavaScript), significantly improving load times and reducing bandwidth costs. This is one of the simplest and most impactful performance optimizations available. Asset minification status: 2 out of 7 CSS files and 2 out of 3 JavaScript files are minified. Minifying the remaining 6 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 reuse.software produces approximately 0.01g 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 12 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for reuse.software. 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.

reuse.software resolves to the IPv4 address 213.95.165.53 and also supports IPv6 (2001:780:215:1::53), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 2 name servers: geoffroy.fsfeurope.org and tennant.fsfeurope.org. 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. Email for reuse.software is handled by fsfe.org with 1 MX records configured: mail.fsfe.org. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. 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 not enabled for reuse.software. While not critical for most websites, DNSSEC adds an important security layer by ensuring DNS responses haven't been tampered with during transit. Enabling DNSSEC is recommended for domains handling sensitive data or financial transactions.

The homepage of reuse.software contains 372 words of visible text content. This is a moderate amount of content. The page is structured with 0 H2 headings, 3 H3 headings, 0 H4 headings. The page includes 7 images. 5 images (71%) 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 29% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 14 internal links pointing to other pages on the same domain and 12 external links pointing to third-party websites. There are 3 external JavaScript files, 7 CSS stylesheets, and 0 iframes on the page. The site implements the following web standards and features: XML Sitemap (helps search engines discover all pages). Notable missing features: robots.txt and Schema.org structured data. Adding these could improve search engine discoverability and rich result eligibility. The website has social media presence across 2 platforms: Twitter (@fsfe) and Github (@search). An active social media presence is a positive trust indicator and helps build brand awareness and customer engagement.

The title tag for reuse.software is well-optimized at 40 characters: "REUSE - Make licensing easy for everyone". The length falls within the ideal range for Google search results, ensuring the full title is displayed without truncation. The meta description is 197 characters (slightly long): "We make licensing easy for humans and machines alike. REUSE solves a fundamental issue that Free Software licensing has ...". 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. A favicon is configured. Open Graph meta tags are configured with 3/4 recommended fields: OG title ("REUSE - Make licensing easy for everyone..."), OG description, OG image (social sharing thumbnail), 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.
