Free trace tool for Zephyr RTOS boosts real-time visibility
Cette publication existe aussi en Français
Percepio has launched Percepio View for Zephyr, a free trace visualisation tool designed to provide immediate insights into Zephyr RTOS behaviour.
The Percepio View trace tool provides a professional analysis experience specifically tailored for the Zephyr ecosystem, enabling users to instantly peer inside their system. Out of the box, users receive clear RTOS-aware timeline views, detailed logs of system and user events, CPU load and task execution graphs, and support for custom tracepoints.
“In embedded development, visibility is everything,” said Johan Kraft, CTO and founder of Percepio. “Percepio View brings powerful trace diagnostics to every Zephyr developer — no barriers, no cost — so teams can stop guessing and start knowing.”
“Tools like Percepio Tracealyzer help make Zephyr development more intuitive and efficient,” said Kate Stewart, Vice President of Dependable Embedded Systems at the Linux Foundation. “This contribution strengthens the ecosystem by empowering developers with deeper system insights, accelerating innovation, and improving the reliability of applications built on Zephyr — across both open source and commercial projects.”

Developers can use View for free, and registration unlocks additional features at no cost. For projects requiring deeper analysis and longer trace capture, Percepio Profile is available as an optional upgrade. Profile builds on View’s foundation with live streaming for long-duration traces, thread timing and execution metrics, memory usage profiling, and visual plotting of application-specific variables.
Users can upgrade further to a full Tracealyzer license when ready for advanced diagnostics and integration with Percepio’s Continuous Observability suite.
Percepio has been an active member of the Zephyr Project for several years, contributing to the TraceRecorder library, which is now part of the Zephyr kernel. This release reflects its broader commitment to expanding the Zephyr development ecosystem. By reducing barriers related to pricing and licensing complexity, Percepio View and Profile make professional observability tools more accessible.
