In their own words
Arduino IDE
Arduino IDE is a free desktop environment for building projects with electronic devices that interact with the physical world. The software page lists version 2.3.10, with downloads for Windows, macOS, and Linux. Its editor provides autocompletion, code navigation, and a live debugger; documentation also covers debugging, the Serial Monitor, and the Serial Plotter. Arduino CLI offers a text-based environment to build, compile, and upload sketches, and manage libraries and boards. Documentation describes synchronizing sketches between IDE 2 and Arduino Cloud through a Remote Sketchbook. Arduino IDE 2.0 is open source, with source code hosted on GitHub. Listed targets include Arduino AVR, megaAVR, SAMD, SAM, Mbed OS Nano, and Mbed OS Portenta. Nightly builds preview incoming releases with updated features and bug fixes. Arduino describes its ecosystem as serving students, makers, and professional developers. The software page states that downloads are provided as is and disclaims express and implied warranties.
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.
