MetaLauncher is a revolutionary open-source gaming ecosystem derived from the philosophical underpinnings of projects like HeroicGamesLauncher, but reimagined as a cross-platform game aggregation engine. Instead of merely launching games, MetaLauncher acts as a digital cartographer for your gaming identity—mapping libraries across Amazon Prime Gaming, Epic Games Store, GOG Galaxy, and beyond into a unified, intelligent interface that learns your preferences.
Imagine your game library not as scattered islands of launchers, but as a constellation of interactive experiences that MetaLauncher harmonizes into one luminous sky. Built on GTK4 with modern responsiveness, this tool doesn't just connect stores—it bridges gaming ecosystems.
"Your games should find you, not the other way around."
MetaLauncher treats game discovery as a conversation between you and your digital collection. It uses preference-based routing (not algorithms) to surface title connections you might never have made. Think of it as your personal gaming librarian who remembers every genre you've explored and suggests pathways, not products.

- Single-pane glass interface displaying games from Amazon Prime, Epic Games Store, and GOG Galaxy with zero redundant logins
- Smart deduplication that recognizes cross-store title ownership and merges libraries intelligently
- Preference-based sorting that weighs genre affinity, playtime, and completion status
- Direct terminal invocation for game sessions
- Custom environment variable injection per title
- Multi-distro support for Linux gaming via Proton, Wine, and native runners
- 37 language packs included out-of-the-box
- Dynamic language switching without restart
- Community-contributed translation memory
- OpenAI API integration for natural language game recommendations
- Claude API integration for deep genre analysis and play session summaries
- Both APIs are opt-in and fully sandboxed with encrypted credential storage
- No telemetry by default
- Local-only preference processing
- API calls are proxied through session-scoped endpoints

API Usage: Integration with OpenAI API and Claude API requires your own API keys. MetaLauncher does not provide, generate, or proxy these keys. All API calls are made directly from your local instance and are not routed through any external servers managed by this project.
Data Handling: MetaLauncher processes all preference data locally. No game library metadata is transmitted externally. API integrations are optional and fully disclosed in the configuration profile.
