Packet captures you can watch. Pick one of 33 protocols — DNS, TCP, TLS, QUIC, BGP, WireGuard — and it animates the exchange packet by packet between client, router, resolver and server, then decodes every header field byte by byte. Click any packet to see the raw bytes. HTTP, HTTPS, TCP and UDP are free; a one-time $4.99 pass unlocks the other 29. Ships in 21 languages.
