IAR Embedded Workbench vs RustRover

IAR Embedded Workbench is an embedded development toolchain with an IDE, optimizing compiler, linker, assembler, and debugger. It supports over 20 architectures, including Arm, RISC-V, 8051, MSP430, AVR, and several Renesas families. The C-SPY debugger provides real-time trace, code coverage, function profiling, and RTOS awareness. IAR C-STAT offers static analysis; IAR C-RUN detects runtime errors and is available for Arm and RX. The toolchain works with VS Code and Eclipse, supports CMake builds, and can integrate with CI/CD pipelines. Supported debug probes include I-jet, I-jet Trace, J-Link, PE Micro, and ST-LINK. Built-in plugins provide RTOS awareness for systems including PX5 RTOS and Zephyr RTOS. The IDE runs natively on Linux and Windows. A 14-day evaluation is available for non-commercial use, but excludes runtime library source code, C-STAT, and MISRA C support and includes limited technical support. Paid subscription pricing is available by request; the subscription combines named-user licenses and build capacity for automated builds and CI/CD.

RustRover is an IDE for Rust developers to code, test, debug and deploy. Project analysis supports completion, inspections, refactoring, navigation, usage searches and syntax highlighting. Its coding assistance includes context-aware completion and generation, on-the-fly analysis, quick-fixes, smart refactorings and live templates. RustRover can install rustup and helps manage Rust files and crate dependencies in Cargo.toml. It includes debugging, build and testing tools, plus project management and dev container support. Plugins from JetBrains Marketplace and custom repositories can add integrations and other features. RustRover runs on Windows, macOS and Linux; BSD-based operating systems are not supported. New users can try the full-featured IDE for 30 days. The non-commercial plan costs nothing for learning, self-education, qualifying open-source contributions, content creation and hobby development, and requires a JetBrains Account. Commercial individual use costs $6.90 a month. The non-commercial tier may send anonymized usage statistics and collects detailed code-related data by default, which users can disable in settings.
