A free browser-based stream deck for OBS Studio. Switch scenes, ride your mixer, fire macros, and trigger sounds from any tablet, phone, or laptop on your network -- no downloads, no accounts, no catch.
OBS is powerful. Driving it with a keyboard while you're hosting, recording, or streaming is not. Most creators end up with hotkeys they can't remember and a mixer they can't see.
Switching scenes mid-show means leaving whatever you were doing -- breaking eye contact, losing your place, stalling the take.
When OBS isn't on top, you can't see levels. When it is, you can't see your game, your guest, or your notes.
You already own a perfectly good second screen. It's charging on your desk. It could be running your whole production instead.
Sparkdeck talks to OBS over WebSocket, so every feature you'd expect from a hardware stream deck is one tap away -- on the device you already own.
Big, tappable scene buttons with live preview thumbnails. Crossfade, cut, or any custom transition with adjustable duration.
Per-source faders, mute buttons, VU meters, and monitor routing. Ride your levels from across the room.
Drop in MP3s and trigger them from a grid of pads. Pro engine handles polyphony, ducking, and per-pad volume.
Chain scene cuts, source toggles, transitions, and delays into a single button. Build a runsheet to step through your show.
Map any Xbox, PlayStation, or Bluetooth controller button to a scene, mute, macro, or transition. Hands-free production.
Add to home screen on iOS, Android, Mac, or Windows. Runs as a fullscreen PWA -- no app store, no install fees.
No install, no account. If you already have OBS Studio 28 or newer, you're halfway there.
In OBS, open Tools → WebSocket Server Settings and check Enable WebSocket Server. Copy the password.
Visit arcusfoundry.com/tools/sparkdeck/app on any device on your network. Enter your computer's local IP and the password.
Scenes, mixer, sounds, macros -- all live on your phone, tablet, or second laptop. Add to home screen to pin it.
Running a podcast or solo show? Sparkdeck and Sparkprompt are designed to work together. One tablet under your camera reads your script while another rides your scenes and mixer.
Enter your OBS host, port, and password once. Both apps read the same setting from local storage and stay in sync.
Your controller mapping carries between apps. Active tab handles input, so two open windows never fight over one pad.
The Sparkforge Suite installer serves both apps over your LAN, with QR codes, offline cache, and the LAN Sync relay built in.
Both apps run on devices going back to 2017. That iPad in the drawer is now a teleprompter. The other one is your stream deck.
No install, no account, no catch. Open it in your browser, point it at OBS, and go.
