PacketScope

PacketScope is a packet capture and analysis tool for people who need an answer, not a wall of packets. You choose what you’re troubleshooting in plain words, such as a website that won’t connect or a slow connection. Then you capture while the problem happens and mark the moment it occurs. PacketScope gives back a verdict: what was observed, what it most likely means, and what to try next. Every connection is broken into five steps (local network, name lookup, connection, secure setup and app response), and the first failed step is highlighted. Every finding links to its exact packets and a filter you can paste into Wireshark, so nothing has to be taken on trust. PacketScope also checks traffic against public threat feeds (Feodo Tracker, SSL Blacklist and Spamhaus DROP), entirely offline, and shows any match as a separate, clearly worded security signal. Other features include before/after comparison, questions in plain English, per-app traffic, a searchable packet log, and support reports that hide IP addresses and domain names by default. Capture, analysis, threat matching and the optional AI wording all run on the user’s own device. There’s no account, cloud or telemetry. PacketScope has native apps for macOS (Swift) and Windows (C#), plus a browser version that analyzes capture files entirely in the browser, which judges can try without installing anything.
