A Stream Deck is a panel of dedicated LCD buttons you press to launch apps, fire macros, switch OBS scenes, run multi-actions, and trigger plugins. Every one of those is an action behind a keypress, and Rebind fires the same actions from any key on the keyboard and mouse you already own.
Bind a key to launch an app, run a macro, or emit a hotkey configured in OBS. Then go where a control surface can't: remap keys, build per-app layers, transform mouse movement, expand text, and drive Rebind from TypeScript, Python, or Rust. Core scripts move across Windows, macOS, and Linux; OS-specific namespaces vary.
The one thing a Stream Deck gives you that Rebind doesn't is the dedicated, labeled physical keys themselves. If you want that tactile surface, the two work side by side. Rebind can run the actions behind it.
