A WebAssembly runtime embedded in Godot game engine projects. Interact with Wasm modules from GDScript.

Accessing Wasm modules via GDScript provides the following benefits. - Sandboxed environment allows safely loading zero-trust mods/extensions to a project. - Single target means that Wasm modules can be built from any language e.g. Rust, Go, AssemblyScript and the single binary can be run on all platforms. - Fast execution compared to GDScript allows for offloading compute-heavy operations or running bots/mods/etc. at high FPS.

This might be useful for loading mods, bot AI, or entire games (similar to the WASM-4 fantasy console), offloading compute-heavy tasks without using GDExtention C++, or just writing some game logic in your favourite Wasm-supported programming language.

Supports Wasmtime, Wasmer, and other runtimes that adhere to the Wasm C API. Basic function and global access, memory operations via the standard StreamPeer interface, and limited WASI support. Installable for both Godot 3 and Godot 4 as a GDExtension/GDNative addon or as engine module.
