sliky1992/gamesync-hub repository overview

⁠GameSync Hub

Self-hosted hub for real-time game-save sync across devices. This image is the central server: a Fastify API + WebSocket sync engine, a SQLite database (Prisma), and a web dashboard. Pair it with the Windows client to sync game saves between PCs automatically.

📦 Source, full docs & Windows client: https://github.com/sliky1992/gamesync⁠

⁠Quick start

docker run -d --name gamesync-hub \
  -p 8080:8080 \
  -v gamesync-data:/data \
  -e STEAMGRIDDB_API_KEY=your_key_here \
  --restart unless-stopped \
  sliky1992/gamesync-hub:latest

Open the dashboard at http://localhost:8080⁠.

Or with Docker Compose:

services:
  hub:
    image: sliky1992/gamesync-hub:latest
    container_name: gamesync-hub
    ports:
      - "8080:8080"
    environment:
      STEAMGRIDDB_API_KEY: "${STEAMGRIDDB_API_KEY:-}"
      API_TOKEN: "${API_TOKEN:-}"
    volumes:
      - gamesync-data:/data
    restart: unless-stopped

volumes:
  gamesync-data:

⁠Configuration

• Port: 8080 (HTTP + WebSocket).
• Volume: /data — holds the SQLite DB and all save versions. Back this up; it's your data.

⁠Tags

• latest, 1.0.0 — linux/amd64.

⁠What it does

• Real-time sync — pushes new saves to other devices over a WebSocket within seconds.
• Content-hash versioning — same save hashes identically on every machine; safe conflict handling (nothing silently overwritten).
• Vault — browse every saved version per game: download, restore (roll back), or prune.
• SteamGridDB cover art and search.

To sync a machine, install the Windows client from the GitHub Releases⁠ page (or the dashboard's Setup tab) and point it at this hub.
