DS Hub (Dedicated Server Hub)

Last updated on October 21, 2025

Overview​

DS Hub (Dedicated Server Hub) provides a persistent WebSocket connection between your dedicated game servers and AccelByte backend services. Use DS Hub to receive realtime notifications (matchmaking events, session updates, backfill proposals, etc.) and to let backend services send administrative notifications to live servers.

This page is the DS Hub overview — for SDK-specific configuration examples, see Configure DS Hub with the SDK. For the full list of server notification payloads and examples, see the Server Notifications reference: Server Notifications.

Key concepts​

  • WebSocket connection: persistent channel between a game server and DS Hub
  • Connection lifecycle: DSHUB_CONNECTED notifications
  • Topic-based notifications: DS Hub delivers messages by topic (for example, BACKFILL_PROPOSAL)

SDK configuration​

For platform-specific instructions and code examples to connect and interact with DS Hub, see the SDK configuration guide: Configure DS Hub with the SDK.
