Patchword vs DomainLens Pro

Select two files or paste two texts and compare them. Select two directories and compare them to see which files have been added, removed or modified, and selectively reset modified files to match the original ones. If files have slightly different names, you can match them by alphabetical order or a custom name map, and selectively rename them afterwards so that the names are equal. Export patches from two compared text files, or apply saved patches to an existing file. Create edit scripts that are applied non-destructively to a text file and export the resulting text.

DomainLens Pro is a one-tap domain reconnaissance toolkit for IT pros, security analysts, developers, and anyone responsible for a domain. Type any domain, IP, or URL and DomainLens Pro runs 24+ specialized probes in two parallel phases, then aggregates the results into a single color-graded report. Browse it across ten organized tabs: • Overview — A–F security grade with a confidence score, top remediation actions, and per-category breakdown • DNS & WHOIS — A, AAAA, MX, NS, TXT, SOA records, TTLs, registrar, expiry, name servers, registration history • Identity (RDAP) — RFC 9083 lookup, abuse contact, EPP statuses, transfer history, privacy-redaction detection • SSL / TLS — full certificate chain, validity, signature algorithm, SANs, OCSP stapling, forward secrecy, and post-quantum readiness (X25519MLKEM768 / SecP256r1MLKEM768) • Headers — HSTS preload eligibility, CSP nonce/hash analysis, X-Frame-Options, COOP, COEP, Referrer-Policy, Permissions-Policy • Email — SPF strict alignment, DKIM key strength, DMARC policy + alignment, MTA-STS, TLS-RPT, BIMI, DANE, full mail-server diagnostics • Web Stack — server fingerprint, technology detection, third-party JS / dependency inventory, JS-derived endpoint discovery • Exposure — sensitive file probes (.git, .env, robots.txt), CORS misconfigurations, dangerous HTTP methods, exposed login portals • Infrastructure — ASN, hosting provider, cloud platform (AWS/Azure/GCP/Cloudflare), CDN/WAF detection, GeoIP, anycast detection, RPKI validation, IPv4 + IPv6 reachability • Intel — DNSSEC validation, CAA records, HTTPS/SVCB records, dangling CNAME detection, zone-transfer test, Certificate Transparency subdomain enumeration, DNSBL reputation, CVE lookup against detected tech via NVD, historical drift tracking Also handles: • IPv4 / IPv6 reverse-lookup mode — paste an IP, get the domain back • Private network mode — paste an internal RFC 1918 IP and get ICMP/HTTP/HTTPS detection, OS fingerprint by TTL, ARP MAC vendor lookup, traceroute (full on Mac; iOS sandbox limits some probes) • Scan history with one-tap re-scan, offline browsing, sync across devices via Google Sign-In • Versioned scoring algorithm with confidence weighting and partial-result handling for slow targets • Post-quantum TLS twin probe to verify hybrid key-exchange support Built for security pros: • Full TLS pinning to the scan backend • No analytics, no ad SDKs, no third-party tracking • Sign-in is optional — without it, no personal data ever leaves the device• When you do sign in, choose any of: Apple, Google, Microsoft, GitHub, or a one-time email code (no passwords, ever)• Native iPhone, iPad, and Mac Catalyst layouts with platform-appropriate menus and Cmd+1–9 keyboard shortcuts on Mac No subscription.
