Godot GDScript AOT & Extension

GDPP compiles GDScript into binaries:

• High performance: compiles to native code and binaries
• Cross-platform: supports desktop, mobile, and Web platforms
• Easy to use: one-click export after enabling the plugin
• Syntax extensions: a more powerful GDScript language

Performance Results

Workload	GDScript	GDPP AOT	Relative performance
Matrix multiplication	3.064 s	30.397 ms	10,080.53%
2D test case	17.776 μs/frame	0.140 μs/frame	12,697.14%

Note: These results were measured on a Mac mini with a 10-core M4 and 16 GB of memory, running macOS 26.6.2 with the official Godot 4.7.2 editor and export templates.

Quick Start

1. Extract the plugin to addons/gdpp, then enable it.
2. Make sure a C++ compiler is installed locally, such as MSVC on Windows.
3. Export the project and wait for the compilation progress bar to complete.

Syntax Extensions

GDPP targets compatibility with official GDScript and plans to support additional syntax. If you encounter compatibility issues or have suggestions for future GDScript syntax enhancements, please share them through an issue.

Plugin Support

Use the GDPP Plugins panel or a YAML configuration to export a GDScript plugin as a compiled GDPP plugin for use in other Godot projects. Using the exported plugin requires neither GDPP nor a C++ compiler. The package retains .gd interface files for resource references and public APIs; plugin logic runs in the native library.

When exporting a whole project, GDPP compiles project scripts outside addons/. To compile a plugin, export it separately.

Export in the editor

Enable GDPP and open the GDPP Plugins bottom panel. Select an installed plugin or enter an external source directory. Edit the generated YAML to choose targets and compilers, import or save a configuration, then click Inspect to view its configuration and script inventory or Export to compile and package it. The target field overrides build.targets; separate names with commas.

The panel works in macOS, Windows, and Linux editors without a separate gdpp command-line installation. Install the compiler or toolchain required by your target platform before exporting.

Export from the command line

Download and extract gdpp-compiler.zip from Release. Keep its directory structure intact. Run the program for your system, or add its directory to PATH.

linux/x86_64/gdpp          # glibc 2.35 or later
windows/x86_64/gdpp.exe    # Windows 10 or later

Save the example below as my_plugin.yaml, set your plugin directory, target platforms, and compilers, then run:

gdpp inspect my_plugin.yaml
gdpp build my_plugin.yaml --targets windows-msvc

schema_version: 1
plugin:
  source: ./addons/my_plugin
godot:
  executable: godot
  # path: /opt/godot
  target_version: "4.7"
build:
  targets: [windows-msvc]
output:
  directory: ./dist
targets:
  windows-msvc:
    platform: windows
    architecture: x86_64
    compiler: cl.exe
  macos:
    platform: macos
    architecture: universal
    compiler: clang++
  android:
    platform: android
    architecture: arm64
    ndk: /opt/android-ndk

• Set plugin.source to your source plugin directory and output.directory to the export directory. Relative paths resolve from the YAML directory.
• Set godot.executable to the Godot program name. Omit path when it is in PATH; otherwise, set it to the executable's directory. Set target_version to the target Godot version, such as "4.7".
• Configure your target platforms under targets. Set compiler to a full path or a program name in PATH; on Windows, use cl.exe or MinGW64's g++.exe. For Android, set the ndk directory.
• Select target names with build.targets or the command's --targets option. Separate multiple names with commas, for example --targets macos,android.

Each export target needs its toolchain: MSVC uses Windows, macOS/iOS use macOS and Xcode, Android uses the NDK, and Web uses Emscripten. Exporting preserves your original plugin.

Crossing Boundaries

GDScript code that makes frequent engine calls may not see a significant performance improvement. We are also optimizing GDPP's compilation process to reduce boundary crossings as one way to improve performance.
