Wireshark
Provides its full packet analysis workspace with extensive detail for specialist work.
Display by apps / domains
TCP Viewer
Groups traffic by app and domain, turning a busy capture into clearer conversations to scan.
Wireshark
Shows packet rows and lets you use filters to find the addresses and protocols you need.
Advanced filters
TCP Viewer
Build focused multi-rule filters in a clear form, so everyday checks do not require complex filter syntax.
Wireshark
Offers a powerful filter language for precise, detailed analysis.

TCP Viewer MCP
Ask your AI agent about the packets
Connect TCP Viewer to Codex or another MCP client. Check capture status, explore interfaces, and find the packets that matter with a plain-language prompt.
Available with TCP Viewer PRO.
Saved captures
Open PCAP and PCAPNG files by drag and drop
Bring an existing capture into TCP Viewer and preview the packets right away, with no fresh recording session required.
Drag in a trace
Drop PCAP or PCAPNG files straight onto TCP Viewer.
Preview immediately
Open the packet list and decoded detail view without a live capture.
Keep the workflow native
Review saved evidence in the same Mac-first packet interface.
Drop capture.pcapng to preview
Inspect without the clutter
Whatever you capture, TCP Viewer keeps the important traffic readable. Filter noise, open decoded fields, and save evidence for the next debug session.
Grouped traffic
Group packets by domain or client
Collapse busy captures into readable conversations by domain or client, then jump straight to the traffic that matters.
Protocol filters
Quickly filter TCP, UDP, DNS, and more
Tap protocol chips to focus the packet list without rebuilding a complex filter every time the capture changes.
Export captures
Save evidence as PCAP or PCAPNG
Package the exact packets you need into standard capture files for Wireshark, teammates, or the next debug session.
