Web Tools
Web tools support SEO, diagnostics, and developer utility workflows. Local tools can build UTM links, generate meta tags, preview Open Graph cards, decode JWTs, create UUIDs, calculate subnets, and generate hashes. Remote checks inspect public robots.txt, sitemaps, redirects, headers, TLS certificates, and DNS records with private networks blocked. Use this category when publishing pages, debugging launches, or validating technical SEO details.
