A native macOS network protocol analyzer for inspecting and exploring
A native macOS network protocol analyzer for inspecting and exploring .pcap trace files. Cocoa Packet Analyzer (CPA) is a fast, document-based PCAP file analyzer for macOS, built entirely in Swift with a SwiftUI interface designed to feel right at home on the Mac. Open any libpcap-format trace file — the same format produced by tcpdump and the standard set of industry network-analysis tools — and CPA dissects every supported protocol, layer by layer, in a clean four-pane document window: • A sortable packet list with analyzer-contributed columns • An outline view showing the full protocol dissection tree • A hex view that highlights the bytes behind whichever field you select • A live filter toolbar for narrowing in on exactly what matters KEY FEATURES — Follow TCP Stream Reassemble any bidirectional TCP conversation and switch between four view modes: Conversation (speech bubbles with packet numbers and flags), ASCII transcript, side-by-side hex dump, and a parsed HTTP request / response view. — Powerful display filtering A single search field doubles as a token-style query builder with sectioned autocomplete, rich-editor popovers for dates and protocol expressions, nested AND / OR / NOT logic, and a saved-query library — all without leaving the document window. Any filter result can optionally be routed into a new document so the original stays intact. — Open Selection in New Window Right-click any packet selection (one or many) and open them in a standalone document with full detail, hex, and filter UI. Save As… / Export… writes a self-contained .pcap that inherits the source's link type and snap length. — Quick Look + Spotlight integration A system-wide Quick Look preview shows a summary card (link type, packet count, time range), top protocols and talkers, a packet-rate sparkline, and a packet table — all without opening the app. The bundled Spotlight importer indexes trace metadata so .pcap documents become searchable from Finder and Spotlight. — Protocol statistics A one-look summary of any trace: a printable bar chart of protocol distribution alongside file metadata — link type, packet count, byte totals, and time span. — Printing Print the packet list, protocol tree, hex view, or statistics chart with progress indication and the standard macOS print accessory panels. — Localization Fully localized in English, German, and Japanese. INCLUDED PROTOCOL ANALYZERS All analyzers are written in pure Swift and ship as part of the app: • Link layer — Ethernet II, IEEE 802.11 (RadioTap), Linux cooked (SLL), Loopback, 802.1Q VLAN, MPLS • PPP & PPPoE — PPP, PPPoE Discovery & Session, LCP, IPCP, IPv6CP, CCP, PAP, CHAP • Network layer — IPv4, IPv6, ICMP, ICMPv6, IGMP, ARP, IPv6 Mobility, OSPF (RFC 2328), BGP, IPsec ESP • Transport — TCP (with full options dissection and stream reassembly), UDP, L2TP • Application & service — DNS, DHCP, DHCPv6, HTTP, HTTP/2 frame dissection (RFC 9113), WebSocket, FTP, SSH, Telnet, SMTP, POP3, IMAP, NNTP, SIP, IAX, SOAP, RADIUS, LDAP, SMB, SNMP REQUIREMENTS • macOS 26 or later • Existing .pcap trace files (libpcap / tcpdump format) Cocoa Packet Analyzer is the perfect Mac-native companion to any tool that records network traffic — a fast, focused, beautifully integrated way to explore the traces you already have.
