Particle Web IDE vs STM32CubeIDE

Particle Web IDE is a browser-based development environment for Particle device platforms. It supports C and C++, firmware debugging, and deployment to Particle devices running Particle Device OS. The supported boards exclude Tracker One and Tracker SoM, and the IDE does not include a device simulator. The Free plan costs nothing, billed forever, and covers 100 devices and 100K Data Operations per month. Basic costs $299 a month per block and includes 100 devices and 720K Data Operations per month per block. Plus costs $599 a month per block, with 100 devices and 5M Data Operations per month per block. Professional and Enterprise use custom pricing: Professional lists premium support options, while Enterprise lists customized Data Operations packages. The available plans therefore specify different device and monthly Data Operations allowances, with custom-priced options for tailored packages or support. Particle Web IDE is web-only.

STM32CubeIDE is a C/C++ environment for editing, compiling, and debugging code for STM32 devices. ST offers an Eclipse-based IDE and a Visual Studio Code variant, and identifies the VS Code version as its primary IDE focus. The Eclipse version supports all STM32 microcontrollers and microprocessors; the VS Code version supports all STM32 microcontrollers. Both are listed for 64-bit Windows, Linux, and macOS.

The IDE includes a C/C++ editor and supports GCC and Clang toolchains. Debugging features include breakpoints, CPU core registers, memory and live-data views, SFR registers, RTOS debugging, and fault analysis. Supported probes include ST-LINK and SEGGER J-Link. ST says the IDE is commonly used with STM32CubeMX and is compatible with TouchGFX Designer, STM32Cube AI Studio, and motor control workbench. The VS Code variant uses CMake and Ninja. Telemetry is optional and can be disabled in Visual Studio Code settings. It is free to download and use, though the ST application is proprietary.
