Deeplinks Toolkit vs deepdig.dev

DeepLinker helps iOS QA and developers work with universal links and custom deeplinks faster. Use DeepLinker to validate AASA configuration, keep a clean link library, import links from pasted text, and run quick or full test sessions with simple pass or fail tracking. Paste raw URLs, notes, or JSON snippets, review extracted links, and test them on device in a focused workflow.

deepdig is a free toolbox of network diagnostics built for sysadmins, DevOps engineers and hosting operators — the checks you run every day, faster and more detailed, with no account and no ads. Enter a domain, IP or paste raw data. Checks run in parallel on our servers and results stream in live, each finding graded by severity with a plain-English explanation of why it matters. TOOLS • DNS diagnostics — records, delegation and glue consistency, full DNSSEC chain validation from the root, propagation across 18 public resolvers, and a hop-by-hop recursion trace • SSL/TLS — certificate chain, expiry, hostname match, trust, protocol versions, HSTS • WHOIS — registrar, dates, EPP status codes for domains; RIR allocation, ASN and abuse contacts for IPs • Mail tester — SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, MX reachability and STARTTLS • Email header analyzer — paste a raw email, get the Received chain as a timed hop-by-hop trace with SPF/DKIM/DMARC verdicts • DNSBL / blacklists — check IPs and domains against major blocklists, Spamhaus included • HTTP headers — security headers, redirect chain, cookie flags, server fingerprint • HTTP/3 — ALPN negotiation, Alt-Svc advertisement and CDN detection • IP info — ASN, announced prefix, rDNS, country and hosting classification • Certificate Transparency log search • Subnet/CIDR calculator and a password generator WATCHES — GET NOTIFIED WHEN THINGS CHANGE Put a domain or IP on watch and deepdig re-checks it for you. You get a push notification only when something actually changes: a certificate crossing 14, 7 or 1 day to expiry (and a recovery notice when it renews), a new blacklist listing or a delisting, or a changed DNS record set. No noise, no daily digests — alerts only on real transitions. BUILT THE WAY YOU'D WANT IT • Results stream in as each check completes — no spinners • Every run is saved as a shareable permalink snapshot • History and side-by-side comparison for any target • Share a URL or domain from any app to open the right tool prefilled • Dark mode that follows your system • No account, no ads, no tracking, no analytics. Free. deepdig is the mobile companion to deepdig.dev — same engine, same results, in your pocket.
