Capture live traffic or open a PCAP or PcapNG file and read it layer by layer, from Ethernet up to HTTP/3: a packet list with columns per protocol, the full dissection tree, and the bytes behind any field you select. Decrypted HTTPS: TLS 1.2 and 1.3 decryption, and with it HTTP/2, QUIC and HTTP/3. Session keys come from a key log file, from the built-in MITM Proxy, or from a PcapNG trace that carries its own keys. MITM Proxy: watch the HTTP and HTTPS requests of your own apps and websites in a live monitor, with headers, bodies, WebSockets, HTTP/2 and gRPC. Connect an iPhone or iPad with a QR code, save flows as HAR files and copy any request as a cURL command. The certificate is created on your Mac and stays there. Apps in your traces: see which app sent or received every packet, and count packets, bytes and share per app. Filter on any field of the packet details, follow TCP streams and UDP flows, print protocol statistics, and preview any trace in Quick Look without opening the app. Add your own protocol analyzers as plugins. In English, German and Japanese. Native on Apple Silicon and Intel. Requires macOS 26 or later. https://www.tastycocoabytes.com/ https://appcast.tastycocoabytes.com/cpa/pad/screenshot.png https://appcast.tastycocoabytes.com/cpa/pad/icon.png https://appcast.tastycocoabytes.com/cpa/pad.xml https://appcast.tastycocoabytes.com/cpa/latest/CPA_latest.dmg
