From capture to test in minutes
Three steps to realistic network stress testing with real protocol simulation.
Use the desktop client to capture live network packets. Identify the exact traffic patterns you want to simulate.
Import PCAPs into the chain builder. Create multi-step protocol sequences with visual timeline editing.
Deploy tests across geo-distributed infrastructure. Monitor results in real-time from any device.
Capture traffic. Replay at scale.
