BYOK (Bring Your Own Key) AI support — use OpenAI, Anthropic, Ollama, OpenRouter, or any OpenAI-compatible endpoint instead of GDevelop's built-in AI
Unlock all premium features — remove watermark/logo, unlimited cloud projects, multiplayer, leaderboard customization, and more
Remove export branding — disable the GDevelop splash screen & watermark without a subscription

How it works

New GDevelop Release → GitHub Actions triggers → Clone repo at tag → Apply patches → Build all platforms → Publish artifacts

Three subsystems work together:

Component	What it does
Patches (`patch/`)	Modifies GDevelop source to unlock premium capabilities and route AI to local proxy
AI Proxy (`proxy/`)	Local server that implements GDevelop's Generation API, but uses your LLM keys
CI/CD (`.github/workflows/`)	Watches for new releases, runs the full patch→build→publish pipeline

Quick Start

Option A: Download pre-built patched release

Go to Releases of this repo
Download the patched GDevelop for your platform
Optionally run the AI proxy for BYOK (see below)

Option B: Run the AI Proxy locally

cd proxy
npm install
cp .env.example .env
# Edit .env with your API keys
npm start

The proxy runs on http://localhost:11400 and translates GDevelop's AI API calls into requests to your configured LLM provider.

Option C: Build yourself

# The CI pipeline does this automatically, but you can run it locally:
gh workflow run build-patched.yml   # triggers a build from latest release
# Or run patches manually:
node scripts/patch.js --repo ../GDevelop --release v5.6.269

Supported AI Providers

Provider	Backend
OpenAI	GPT-4o, GPT-4-turbo, o1, o3, etc.
Anthropic	Claude Opus, Sonnet, Haiku
Google	Gemini 2.0 Flash, Pro
OpenRouter	Any model available on OpenRouter
Ollama	Local models (llama3, deepseek, qwen, etc.)
OpenAI-compatible	Any endpoint that speaks the OpenAI chat/completions API

Architecture

┌─────────────────────────────────────────────────┐
│  GitHub Actions (.github/workflows/build.yml)   │
│  ┌───────────────────────────────────────────┐  │
│  │  1. Watch releases (schedule + webhook)   │  │
│  │  2. Clone 4ian/GDevelop at release tag    │  │
│  │  3. Run patch.js → modify source          │  │
│  │  4. Build macOS/Linux/Windows             │  │
│  │  5. Upload artifacts to GitHub Releases   │  │

┌──────────────────────────────────────────────────┐
│  AI Proxy (proxy/) — runs on user's machine      │
│  ┌────────────────────────────────────────────┐  │
│  │  Express server on localhost:11400         │  │
│  │  Implements /ai-request endpoints          │  │

└──────────────────────────────────────────────────┘

Limitations

Cloud services that require GDevelop's backend (gd.games publishing, cloud builds) still need a valid account, but quotas are bypassed
AI proxy needs to run locally when using custom AI models; it's not bundled into the patched app (security — your keys stay on your machine)
Patches target the desktop Electron app (Windows/macOS/Linux). The web app at editor.gdevelop.io cannot be patched this way
