What HeyVR Gameplay SDK is

HeyVR Gameplay SDK connects games published on heyVR with the platform’s APIs and related features. Developers can use its Leaderboard API to create and manage leaderboards and access scores and user-specific data. Arena adds matchmaking, lobbies, and multiplayer server options: a WebSocket game server for games with more than two players and a peer-to-peer server for 1v1 games. The Inventory API stores and manages items players can unlock or purchase. Savegame stores player data on heyVR servers and syncs it across the user’s devices, but saving progress currently requires an authenticated user. The SDK is free for games published on heyVR and can be added through NPM or injected into a game build. It supports WebXR and browser-based VR. Submitted builds must pass review before publication. Developers can contact the heyVR Discord community for support. Organizations can register for free and own unlimited game projects and members.
