DeckStream

Open-source Steam Deck launcher

Your library lives on your storage.

Queue a PC game from your phone. DeckStream mounts the game folder from your WebDAV storage and runs it locally on your Steam Deck through Proton.

From storage to Steam Deck

  1. Serve your library

    Expose authorized game folders from your NAS, Nextcloud or another WebDAV server using the DeckStream storage API.

  2. Queue a game

    Choose a folder in the phone companion or the optional Decky panel. Check its progress from the queue.

  3. Launch through Proton

    The daemon on the Deck mounts the folder with rclone and caches the data the game reads. The Deck renders the game locally.

Try it without a Deck

Run the phone companion and a mock library locally with Node.js 22.

git clone https://github.com/hffgzktbcc-blip/deckstream.git
cd deckstream
npm start

Open http://127.0.0.1:8765 to try the library and queue.

What’s been verified

API and browser checks exercise the current own-storage flow with mock storage. An independent clean-device launch is still unconfirmed.

v1.0.0 predates the own-storage changes. Earlier device timings cover the predecessor runtime. LAN NAS performance and game compatibility are still open questions for this revision.
