In their own words
ESP-IDF Extension for VS Code
ESP-IDF Extension for VS Code lets developers create, build, flash, monitor, debug, and manage projects for Espressif chips inside Visual Studio Code. Its project wizard starts from ESP-IDF examples or configured framework templates. Builds use CMake and Ninja, and devices can be flashed over UART, DFU, or JTAG. Debugging includes device sessions and postmortem work with a core dump or GDB stub. Additional tools include code coverage, heap tracing, application-level tracing, binary size analysis, and an eFuse viewer. The extension can install ESP components and add Arduino as an ESP-IDF component; QEMU can emulate debugging and monitor output. Documented development environments include Docker, WSL, SSH, Dev Containers, Codespaces, and browser-based VS Code. The extension also exposes ESP-IDF commands to language-model integrations such as Copilot through MCP servers. It is free and open source under Apache License 2.0, for Windows, macOS, and Linux. Visual Studio Code is required.
STM32CubeIDE
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.
