Everything Frame Bench does
One frame table underneath. Edit a byte and every view updates.
Editing and integrity
Every edit is undoable and checked.
Byte-level hex editing
Type into any offset, or cut, copy and paste ranges as hex, text or a C array.
Health check auto-fix
Recomputes lengths and checksums after every edit, padding included.
Undo, redo, revert
Undo a whole batch in one step, or revert every changed frame at once.
Notes and comments
Annotate a byte range or a frame. Exports keep them.
Crafting frames
From a guided form to a batch run across a whole capture.
Guided builders
TCP, UDP, DNS, ICMP, ARP and HTTP from real fields, with checksums done for you.
Craft lab
Expressions, series, mutation and fuzzing, and ready-made multi-frame scenarios.
Batch apply
XOR, add a template, rewrite addresses or recalculate seq/ack across many frames.
Templates and library
Save custom layouts and crafted frames. Reuse them in any capture.
Analysis and decryption
The views you expect, next to the frame table.
TLS and QUIC decrypt
From a keylog or PcapNG secrets, with certificate extraction and search.
Conversations and hosts
Protocol hierarchy, hosts and ports, and a graph that selects frames on click.
RTP streams
Loss, reordering and jitter per stream.
Filter language
Autocomplete, presets and fields like http.status and frame.cap_len.
Extract field values
Every distinct value of a field, counted and traced to its frames.
Signature search
Find byte patterns across the whole capture.
Workspace
Pick up where you left off.
Sessions
Save frames, templates, rules and filters as one file. Restore it later.
Views, filters, coloring
Saved table views and rules, with a live preview as you tune a color.
Compare frames
Byte diff of up to five frames. Export as HTML, Markdown or unified diff.
Built for big captures
Multi-gigabyte files without a frozen window.
Large-capture mode
Indexes the file and loads only the range or filter you pick.
Streaming export
Writes filtered output straight to disk in chunks.
Live re-indexing
Watches a growing capture and offers its new frames.
Export what changed
The whole capture, only your edits, or a filtered slice.
.pcap and PcapNG
With embedded TLS secrets and custom metadata.
HTML report
A color-tinted frame list you can share without the capture.
Raw-frames JSON
Lossless, diffable, with notes and comments.
Settings file
Templates, presets and rules in one portable file.
Transform and import
Change what a frame is, or bring in what was never a pcap.
TCP and UDP conversion
Convert a stream either way. Seq/ack and checksums are rebuilt.
IPv4 and IPv6 conversion
Stateless NAT64 translation through a configurable /96 prefix.
Fiddler SAZ and HAR import
Sessions arrive as real, editable TCP and HTTP frames.
Rewrite addresses
A saved MAC, IP and port preset, applied to every frame in scope.
Edit timestamps
Set a time exactly or shift by an offset, per frame or for the whole capture.
