What SEGGER Ozone is
SEGGER Ozone is a graphical debugger and performance analyzer for embedded applications targeting Arm and RISC-V microcontrollers or microprocessors. It supports source-level debugging for C, C++, Rust, and Assembler, alongside instruction trace, code profiling, and code coverage tools. Developers can use toolchains including Embedded Studio, GCC-based IDEs, Clang/LLVM, IAR, and Arm Compiler. Ozone works with J-Link and J-Trace probes, and can connect to third-party probes and simulators through a GDB server. RTOS plug-ins, a SmartView middleware interface, and target terminal I/O using RTT, SWO, or semihosting are included. Scripts and a console interface can automate nearly all graphical-interface actions, including event-triggered actions. Ozone supports remote debugging, conditional breakpoints, and exception breakpoints, and runs on Windows, macOS, and Linux. Commercial use requires a perpetual Commercial-use License. The single-user license is €798, paid once and includes a 12-month Support & Update Agreement; German sales tax is excluded. Some J-Link and J-Trace models include an Ozone license.

Getting started
- Open the SEGGER Ozone product website
- Install Ozone on Windows, macOS, or Linux meeting the minimum hardware requirements
- Connect a J-Link or J-Trace probe, or use a third-party probe through a GDB server
- Select a supported toolchain such as Embedded Studio, GCC-based IDEs, Clang/LLVM, IAR, or Arm Compiler
- Purchase the Commercial-use License for commercial work unless your listed probe includes an Ozone license
- Configure source debugging, analysis tools, RTOS plug-ins, terminal I/O, or automation scripts
Verdict
Ozone combines source debugging, performance analysis, and automation for embedded development across three desktop operating systems. Commercial buyers should check whether their probe includes a license or requires a separate purchase.
