DomainDig is a fast, no-frills domain inspection tool for developers, sysadmins, and anyone who manages or troubleshoots servers and infrastructure. Enter any domain and run a full diagnostic in seconds: DNS: query A, AAAA, MX, NS, TXT, CNAME, SOA, SRV, CAA, and DS records including wildcard entries, with TTL values, DNSSEC status, and reverse DNS (PTR) lookup for the resolved IP. SSL/TLS: inspect the full certificate chain — common name, SANs, issuer, validity dates, TLS version and cipher, and days until expiry with automatic color-coded warnings. Email Security: parse SPF, DMARC, DKIM, MTA-STS, and BIMI records with pass/fail indicators so you can verify email deliverability at a glance. HTTP Headers: fire a HEAD request and review all response headers, with security-relevant headers (HSTS, CSP, X-Frame-Options, and more) highlighted automatically. Redirect Chain: trace every HTTP redirect hop from initial request to final destination, with status codes at each step. Reachability & Ports: measure TCP latency on ports 80 and 443, and scan common ports (FTP, SSH, SMTP, MySQL, PostgreSQL, and more) to see what's open. IP Geolocation: look up the hosting org, city, region, and country for the resolved IP, with a live map view. Ownership & Subdomains: pull registrar, registration and expiry dates, and nameservers via RDAP, check domain availability, and discover subdomains. Every result loads in parallel and independently, then rolls up into a risk score with plain-language insights. Go beyond a single lookup: - Monitor domains on a schedule and get alerts when DNS, TLS, or email records change. - Group domains into Workflows and run them as a batch. - Compare any two domains side by side, and track changes across a full snapshot history. - Run structured Audit sessions with checklists, findings, and evidence. - Export as text, CSV, JSON, Markdown, or PDF — single reports or whole portfolios. - Home Screen widgets, Shortcuts, and a share extension put it where you work. - Optional iCloud sync keeps your domains and history across your devices. - A built-in local API exposes reports to your own scripts and automation. Local-first by design: your data stays on device unless you export, share, or sync it. No accounts. No ads. No tracking.

NetSleuth is a powerful network diagnostic toolkit for iPhone and iPad. Whether you're a developer, IT professional, or just someone who wants to understand what's happening on their network, NetSleuth gives you professional-grade tools in one clean, fast app. * Speed Test Measures your connection the way it should be measured. Tests download, upload, latency, jitter, loaded latency, and packet loss — then gives you a Bufferbloat Grade (A–F) showing how your connection performs under real load. Powered by Cloudflare. * Ping Ping any host with a single burst or continuous mode. Watch latency in real time on a live scrolling graph with color-coded results and timeout detection. * Traceroute Trace the full path to any host with live reverse DNS lookups showing real router and infrastructure hostnames at every hop. * DNS Lookup Query A, AAAA, MX, TXT, CNAME, and NS records for any domain. * DNS Propagation Check if your domain has propagated across 10 major DNS servers worldwide including Google, Cloudflare, Quad9, and AdGuard. * DNS over HTTPS (DoH) Test whether your device is using encrypted DNS. Checks 6 major DoH providers and estimates your protection level. * Port Checker Scan common ports on any host to see what's open or closed. * WHOIS Look up domain registration and ownership details instantly. * SSL Inspector Inspect SSL/TLS certificates — view issuer, validity dates, and days until expiry. * WiFi Info See your local IP, external IP, subnet, gateway, and DNS. Enable location permission to reveal signal strength in dBm, SSID, BSSID, and channel with 2.4/5 GHz detection. * IP Info Geolocate any IP address with a map view, ISP, timezone, region, and coordinates. No ads. No account required. No data collected.
