Real-time monitoring
Watch bus traffic live as your system runs — timestamps, framing, and decoded payloads instead of raw hex guesswork.
Products
In developmentCommTuner
A high-performance, multi-protocol communication interface and test tool for embedded systems. One device, one unified USB API — for every serial bus on your bench.

What it does
Packet injection
Craft and inject frames onto the bus to reproduce edge cases, probe error handling, and script fault-condition tests.
Device emulation
Stand in for hardware that doesn't exist yet — emulate a sensor, an actuator, or a whole peer node while the real one is still on the bench.
Protocol analysis
Decode, filter, and inspect traffic across protocols to find the malformed frame, the timing violation, or the undocumented behavior.
Who it's for
- Embedded developers debugging communication issues between devices
- Test and QA teams automating protocol-level validation
- Engineers doing protocol reverse-engineering and analysis work
Built by people who need it
CommTuner wasn't a product idea looking for users. It grew out of our own consulting work— bringing up boards, debugging bus traffic, and emulating missing hardware on real client projects. We're building the tool we reach for every day, and packaging it so your team can reach for it too.
