About Arduino IDE
Arduino IDE 2.x is a major rewrite of the Arduino development environment that shares no code with the 1.x line. It is based on the Theia IDE framework and built with Electron.
Backend operations such as compilation and uploading are handled by an arduino-cli instance running in daemon mode. The project set out to preserve the interface and user experience of the previous major version to make upgrading frictionless, which makes it a familiar choice for anyone programming Arduino boards.
Highlights
- Complete rewrite based on the Theia IDE framework and built with Electron
- Compilation and uploading handled by arduino-cli running in daemon mode
- Keeps the interface and user experience of IDE 1.x for an easy upgrade
- Nightly builds available alongside release versions
