as2wasm - Apache Royale Actionscript to WebAssembly Transpiler

as2wasm is an Apache Royale tool that transpiles Actionscript (AS3) source code directly to WebAssembly (Wasm) modules. Version 0.1.5 is the latest stable release, part of the Apache Royale 0.9.x series. It enables running legacy Flash/Actionscript applications in modern browsers without the Flash plugin, targeting WebAssembly for near-native performance. Key differentiators: it is the only open-source AS3-to-Wasm transpiler, integrates with the Apache Royale framework for cross-platform UI compilation, and supports both ActionScript 3 and optional SWF input via a separate binary variant. Release cadence follows Apache Royale's quarterly releases.
