NEW • Path MTU Discovery : find the largest packet a route actually carries, and catch the MTU black holes that let a connection start and then stall. Names the constricting hop and gives a safe inner MTU for WireGuard, IPsec, OpenVPN, GRE, and PPPoE. IMPROVED • HTTP(S) Check : security headers graded A-F, HTTP/3 probed for real rather than trusted, IPv4 and IPv6 measured separately, plus a full DNS / TCP / TLS / time-to-first-byte breakdown. • Speed/Latency Baseline : size presets now reach 96 MB. CHANGED • The website and Universal Links moved to netdebug.app. netdebug:// links are unaffected. Questions or bug reports? https://netdebug.app/support.html

New Tools • NTP Time Check : run an SNTP query against any NTP server to read your device's clock offset and round-trip delay, plus stratum, leap indicator, reference ID, and Kiss-of-Death detection. • External Port Check : see whether the internet can actually reach you. Our server connects back to a chosen port on your public IP and reports open, closed, or filtered, ideal for verifying port forwarding and inbound reachability. It complements Port Scan, which probes outbound from your device. Run History and Trends • Run History: every manual run and automation step is now saved on your device with its tool, target, time, duration, status, full output, and metrics, so you can look back instead of testing again from memory. • Trends: line charts turn those saved runs into a picture over time: download and upload Mbps, latency, jitter, packet loss, NTP clock offset, and HTTP response time, filterable by target and time range. • Re-run, export, or delete any past run: reach history from a Quick Access row, or per host from the Host Tools screen.

Introducing NetDebug Toolkit 2.0 NEW • My Automation: chain multiple tools into a one-tap workflow with a combined PDF, PNG, or text run report. • Universal Links: open any tool from a shared URL. Read more about this here - https://netdebug.developerinsider.co/docs/deeplinks.html • Export and Import: portable JSON for automations and Saved Hosts. • Reverse DNS (PTR): DNS Lookup and DNS Record Explorer now auto-detect an IPv4/IPv6 literal and switch to a PTR query. • Copy Deeplink: every tool and saved automation can copy its own shareable Universal Link. • Apple TV (tvOS) parity: every tool, Saved Hosts, My Automation, the docs viewer, import/export available on Apple TV.
