SEGGER Ozone review
A deep standalone debugger for ARM and RISC-V teams working across code, trace, and performance.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SEGGER Ozone is a standalone source-level debugger and performance analyzer for embedded applications running on ARM and RISC-V microcontrollers. It is aimed at teams working with C, C++, Rust, or assembler who need more than basic breakpoints and register inspection. Ozone runs on Windows, macOS, and Linux and connects through J-Link, J-Trace, or a GDB server. Its single published plan, Ozone, includes graphical debugging and performance analysis capabilities.
The standout feature is the breadth of embedded diagnosis in one environment. Developers can use conditional code and data breakpoints, inspect registers and memory, analyze Cortex-M exceptions and vector catches, and work with instruction tracing. RTOS awareness covers embOS, FreeRTOS, ChibiOS, NuttX, and Zephyr. Code profiling, code coverage statistics, and power profiling extend the workflow from finding defects to examining runtime behavior and resource use. C-language scripting supports workflow automation, while remote debugging works through J-Link Remote Server or a tunnel server.
According to the vendor’s pricing information, Ozone is a paid product with a perpetual license model. Certain J-Link and J-Trace products include an Ozone license. The published plan combines source debugging, trace, profiling, coverage, scripting, RTOS awareness, and remote access rather than separating these capabilities across multiple listed tiers. Choose Ozone if your team needs a dedicated embedded debugger for ARM or RISC-V and values detailed execution and performance analysis. Teams seeking a free debugging tool or a broader, non-embedded development environment should consider alternatives.
