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.
NuEclipse
NuEclipse is Nuvoton’s free development environment for creating, building, and debugging NuMicro projects on Windows and Linux. The NuMicro 8051 edition targets NuMicro 8-bit devices, while the ARM edition supports NuMicro Cortex-M projects and NuMicro Cortex-A bare-metal projects. Nuvoton lists SDCC for the 8-bit variant and GCC for Cortex-M. Both variants use the Nu-Link debugger, with integrated debugging and flashing. The listed ARM downloads for Windows and Linux are version V1.02.029, dated 2025-03-06. Nuvoton also lists a NuMicro Cortex-M Pack for Visual Studio Code, supporting project building, programming, and debugging on Windows and Linux. Both NuEclipse plans cost nothing. The maker links to technical support, a technical community, a learning center, FAQs, and technical blogs. Nuvoton was founded in 2008 and is headquartered in Hsinchu, Taiwan. Its stated focus includes microcontroller and audio, cloud security, battery monitoring, component, and visual sensing ICs. Security guidance asks for encrypted vulnerability reports and allows seven business days for an initial response.
