Västerås, Sweden – 5 June 2025 – Percepio®, the leader in real-time observability for embedded systems, today announced the release of Percepio View for FreeRTOS, a free trace diagnostics tool that delivers professional-grade runtime visibility to the global FreeRTOS developer community.
Available now at https://traceviewer.io and featured on FreeRTOS.org, Percepio View allows developers to visually trace FreeRTOS application behavior, identify performance bottlenecks, and troubleshoot complex issues – quickly and without cost.
“Percepio has been supporting FreeRTOS developers with trace diagnostics since 2012, and we’re proud to take that commitment even further with Percepio View,” said Johan Kraft, CTO and founder of Percepio. “By making core trace capabilities freely available, we’re empowering the global FreeRTOS community with the tools to better understand their systems, solve tricky bugs faster, and build more reliable embedded products.”
“Percepio View lowers the barrier for real-time system diagnostics and makes it easier for developers to understand what their FreeRTOS-based system is really doing,” said Richard Barry, FreeRTOS Founder and Head of IoT Technology Strategy at Amazon Web Services (AWS). “This is a valuable addition to the FreeRTOS ecosystem and aligns with our commitment to providing developers with accessible, high-quality tools.”
