Our review
Pros	Supports a wide range of microcontroller and processor families Combines firmware uploads, probe-based debugging, and unit testing Works with VS Code, Eclipse, and Sublime Text	Runs firmware on virtual Cortex-M and Corstone targets. Models virtual I/O, streaming channels and host BSD socket connections. Supports Python test automation and cloud CI/CD integration.
Cons	Focused on embedded development rather than general-purpose software work Probe-based debugging depends on supported hardware probes Project setup uses platformio.ini environments	Focused on simulation rather than the full development workflow. The cloud virtual-device subscription is usage-priced after a 30-day trial. Some cloud development-kit models are offered through a partner service.
Our verdict	PlatformIO IDE is an open-source embedded development environment built on Visual Studio Code. It is suited to individual developers and teams working across microcontrollers, processors, boards, and embedded frameworks. Its supported… Read the review →	Arm Virtual Hardware (AVH) provides virtual targets for running and testing software for Arm-based processors, so teams can work on firmware without physical hardware. It is aimed at developers who need to simulate Cortex-M processors or… Read the review →
