Not trying to replace Wireshark. Built for what comes after it.

Frame Bench edits and crafts captures you already have. It does not sniff live traffic.

What sets us apart

Five purpose-built packet builders

Stream, DNS, ICMP, ARP and HTTP, from real fields instead of code.

Drag a template, build a frame layer by layer

Drag a template onto a frame's layer stack to add the next header.

Decrypted traffic, saved as a real pcap

Write decrypted TLS and QUIC traffic back out as a standalone pcap.

Edit and craft in the same tool

Edit and craft in one UI, on the same frame data.

A safety net most of them skip

Health check fixes lengths and checksums, padded frames included.

Built for the step after capture

No live capture, on purpose. Use it after Wireshark runs out of road.
