PacketFlow Lens
Free tcpdump analysis with packet flows and source evidence
Free, browser-based tcpdump analysis. Paste capture text to visualize TCP, UDP, DNS and ICMP traffic, inspect the source lines behind findings, and plan your next checks. No account, installation or file upload required. Pasted logs and results stay in the analysis area and are never saved or sent to a server. Includes sample captures, packet diagrams, capture settings and a clear-input button. Text summaries only; PCAP uploads are not supported.
Hi Product Hunt! I'm Black K, and I'm sharing PacketFlow Lens: a free tool for making tcpdump text easier to read.
Paste a capture excerpt to follow packet flows, inspect the exact source lines behind each finding, and choose what to check next.
It's free to use, with no signup or installation. Your pasted logs and analysis results are processed in an isolated browser area; they are not uploaded or saved.
You can explore TCP connection setup, repeated SYN packets, zero-window conditions, DNS response timing and ICMP messages. Findings stay tied to the text you provided, with capture limits and uncertainty shown alongside them.
Start with a built-in sample, or paste your own tcpdump text. Use Clear input above the capture box to remove the current input and results before starting again.
This is a text-summary analyzer, so it does not accept PCAP files or reconstruct a complete network path.
Try it free: https://quirky-guy.com/tools/tcp...
I'd welcome feedback on which capture formats and troubleshooting cases would be most useful to support next.
