The Quest for Portability in Arduino IDE 2.0 As of 2026, in the same way the classic Arduino IDE 1.x does . While the legacy version allowed users to create a simple portable folder within the installation directory to keep all libraries and board cores self-contained, the modern IDE 2.x—built on the Theia framework and Electron—stores these dependencies in fixed global system directories.
