Eclipse Che vs IAR Embedded Workbench

Eclipse Che is an open-source development environment that runs IDEs in Kubernetes. Users create workspaces from a Git repository or sample, then access them online through a browser. Visual Studio Code and JetBrains IDEs are available. Workspace definitions use Devfiles, YAML files that can be versioned with application source code, and a devcontainer configuration is listed. GitHub, GitLab, and Bitbucket identities can connect through OAuth. Teams can share a development setup by URL, and Che can run on public or private Kubernetes clusters, including self-hosted deployments. Access uses OIDC authentication and Kubernetes RBAC authorization. Enterprise support includes air-gapped networks, TLS certificates, proxies, and FIPS. Code is cloned to persistent storage by default, but other file changes disappear when a workspace stops unless stored on a persistent volume. Che is free, with no stated usage limits.

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.
