Build places in Unreal Engine. Publish them. Play them together.

Website · Creator docs · MantleCore releases

Mantle is a platform for player-made worlds built on Unreal Engine 5. Creators build places in the Unreal Editor with the MantleCore plugin and publish them to Mantle, and players join them through the Mantle client.

• Author in Unreal. MantleCore adds Mantle's tools to the editor: build and convert your content, check it, upload it, and press Test locally to play it in the real client.
• Script in your language. Write gameplay in Luau, TypeScript or Python against one Mantle API, or use the visual graph editor.
• Host your own servers. Run a community server for your place on Linux or Windows; players find it under the place's Servers list.

Mantle's game client, servers and backend are developed privately.

1. Install Unreal Engine 5.8.
2. Get MantleCore and add it to your project.
3. Follow the creator docs to build and publish your first place.
