OpenFL Overview
OpenFL is a Haxe framework for building games and applications that can target desktop, mobile, web, and native platforms. OpenFL is not distributed as a native Windows or macOS installer; the verified offline package is the official OpenFL 9.5.2 Haxelib ZIP from the OpenFL GitHub release. Developers install this package into a Haxe/Haxelib environment and then add platform SDKs for the targets they need. For offline use, download the Haxe compiler, OpenFL Haxelib ZIP, Lime and other required Haxelib dependencies, then import them from a local package cache. The same Haxelib ZIP applies to Windows, macOS, and Linux development machines because it is a framework package rather than an OS-specific desktop application. The OpenFL offline installer is the standalone setup distribution for Windows/macOS/Linux, with the full setup file suitable for offline deployment on developer workstations and CI/build machines that cannot reach the vendor's update servers during install.
