What Is Stream Deck?

Stream Deck puts your most-used actions on physical, programmable keys. Each key on most models is a small LCD display that shows a label, icon, or live status — so you always see what each key does and whether it is currently active.

You assign actions using the free Stream Deck software on Windows or macOS. Drag an action onto a key and it is ready. Because the keys show their own labels, there is nothing to memorise and no guessing which shortcut does what.

Keyboard shortcuts can technically do much of what Stream Deck does. But hotkeys have a focus problem. If you are inside one app and try to fire a shortcut meant for another, it may not work because the wrong window has focus. You end up switching back and forth just to run a single command — unreliable in the middle of a game, a meeting, or a focused work session.

Stream Deck routes around this. Its software integrates directly with applications. When a key is pressed, it communicates with the target app in the background — no focus switching, no Alt-Tab, no uncertainty about whether the command actually landed.

Each key can launch an app, trigger a hotkey, run a sequence of commands, switch to a different layout, or call into a plugin connected to a specific service. Because the keys are LCD displays, the hardware also acts as a live status layer — showing mute state, recording status, scene state, or any other information your apps expose.

The result is a device that is both input and display. You see the current state, act on it with a press, and watch the key update. This makes it useful beyond automation — it reduces the need to glance at multiple app windows to know what is happening.

Stream Deck ships with built-in actions covering the most common tasks: launching apps, opening websites, controlling media playback, setting up hotkeys, and adjusting system volume. These work immediately with no additional setup.

Plugins extend this to specific apps and services. Install the Spotify plugin and you get play, pause, skip, and volume controls. Install a smart lighting plugin and you can control your room lights from a key. Most plugins are free and install with a few clicks.

The Elgato Marketplace is the central place for everything that extends your setup — plugins, pre-built profiles, icon packs, and soundboards. You can browse directly from the Stream Deck app or from a web browser.

The core idea — visible, physical controls mapped to software actions — applies across a wide range of workflows.

Profiles, pages, and folders are what keep Stream Deck from collapsing into one overloaded screen as your setup grows. Profiles are the top level — a meeting profile, editing profile, or admin profile should feel like a different control surface built for a different mode of work.

Pages extend a profile horizontally when one screen is not enough. Folders group related actions under a single key so they are available when needed but do not occupy permanent top-level space.

Smart Profiles go a step further: Stream Deck can automatically switch to the matching profile when you change apps. Open Photoshop and your editing shortcuts appear. Switch to a game and your game controls take over — no manual switching required.
