deepdig.dev vs Agent Information Companion

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.

Check which AI coding agents on your Mac are working or waiting for input, wherever you are. IMPORTANT: AgInOl Companion is not a standalone monitor. Before using it, download AgInOl for Mac from https://aiia.li/apps/aginol, install it on the Mac where your agents run, and keep it open. Your Mac and iPhone or iPad must use the same Apple Account with iCloud enabled. Whether you are beside the Mac or 500 km away, the app gives you a read-only view of the latest deck snapshot. The devices do not need to be on the same Wi-Fi network. AT A GLANCE • See which agents are WORKING, IDLE, NEED YOU, or NOT FOUND • Review open sessions, project titles, models, and elapsed time • Check available token and rate-limit usage, including reset times when reported • Open an all-agents summary • See the snapshot age at all times, with stale data clearly indicated HOW IT WORKS AgInOl for Mac reads local session files from supported coding tools and sends a reduced status snapshot through iCloud. The companion does not run or control agents. For current updates, keep the Mac app running and the Mac online. iCloud delivery can take seconds to minutes. Supported tools are Claude Code, Codex, OpenCode, and Kimi Code.
