PACKET ENGINEERING SOFTWARE
See the packet.
Control the test.
Three focused desktop applications for creating traffic, generating mobile-core sessions, and editing captures without hiding the protocol details.

Purpose-built tools for engineers who need to know exactly what went onto the wire.
01 / 4G & 5G CORE
Mobile Core Generator
Realistic 4G/5G core traffic without a live network, SIM cards, or radio hardware.
Build correlated GTPv2-C, PFCP, GTP-U, and RADIUS scenarios; model mobility; inspect every generated message; and run the same work from the GUI or CLI.

02 / CAPTURE ENGINEERING
PCAP Workbench
Edit any network capture without breaking it — fully offline.
Change fields or payloads, follow SIP calls and streams, repair lengths and checksums, compare captures, anonymize sensitive data, and save the result as PCAP or PCAPNG.

03 / PACKET CREATION
Cat KARAT Packet Builder
Build and send custom packets in a few clicks.
Compose protocol stacks visually, edit raw bytes, run multiple streams, import packets from captures or hex dumps, and automate repeatable tests with scripts and presets.

DESIGNED FOR REAL LABS
Local tools. Visible protocols. Repeatable results.
Work offline. Keep captures, subscriber data, and test traffic inside your own environment.
Stay close to the wire. Inspect fields, bytes, checksums, tunnels, and correlations instead of trusting a black box.
Move from exploration to automation. Start in the GUI, then repeat the workflow from scripts or the command line.
