JitterTrap is open-source software for network test and measurement. Sunny Beach Labs is the project's steward—we maintain the codebase, guide its direction, and ensure it remains a reliable tool for engineers who depend on it.
What It Does
- Traffic Analysis — Packet timing, throughput, inter-packet gaps
- TCP Analysis — RTT, window size, retransmissions
- Network Impairments — Inject delay, jitter, packet loss
- Triggered Capture — Automatic packet capture on threshold events
What Stewardship Means
Being the upstream maintainer of an open-source project is more than writing code. It means taking responsibility for the project's long-term health:
- Development — Building new features, fixing bugs, improving performance
- Documentation — Writing and maintaining guides, API references, tutorials
- Testing — Developing comprehensive test suites, ensuring releases don't break existing functionality
- Release Process — Managing versioning, changelogs, and stable releases
- Infrastructure — Paying for hosting, CI/CD pipelines, project websites
- Community — Reviewing contributions, responding to issues, guiding technical direction
We do this because JitterTrap is the foundation of our hardware products. Maintaining a healthy open-source project benefits everyone who uses it—including us.

The Platform Matters
JitterTrap runs on Linux. You can run it on any system—many users do, and it works well. But timing measurements are sensitive to their environment: background processes, kernel scheduling, and network stack contention can all add noise to your data.
The JT-10.1 and JT-1.1 remove those variables: a tuned OS, dedicated hardware, nothing competing for resources. When you're chasing microseconds, you don't want to wonder whether the artifact is in the network or in your measurement rig.
