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.
nRF Connect for VS Code
nRF Connect for VS Code is a free extension for developing, building, and debugging applications based on the nRF Connect SDK. It supports nRF91, nRF70, nRF53, and nRF52 Series devices, with interfaces to the compiler and linker and an RTOS-aware debugger. Configuration tools include a DeviceTree Visual Editor and a Create New Board wizard. The environment includes a built-in terminal and both command-line and graphical interfaces, with integrated flashing listed. The product consists of four Nordic extensions: nRF Connect for VS Code, nRF DeviceTree, nRF Kconfig, and nRF Terminal. Nordic says all four must be installed and used together for the product to work correctly with supported SDKs and provide all features. The main extension is available through the Visual Studio Code Marketplace; Nordic documentation also lists the extensions in the Open VSX Registry for VSIX-compatible editors. It runs on Windows, macOS, and Linux. Nordic identifies nRF Connect for Desktop and nRF Command Line Tools as additional desktop tools, and recommends its nRF Connect SDK Fundamentals course for getting started. Nordic Semiconductor is headquartered in Trondheim, Norway, and was established in 1983.
