StreamNumDeck turns the numpad and six navigation keys into a tactile control deck for streaming, gaming, and everyday automation. Num Lock switches between two layers with up to 44 actions per profile. Control OBS scenes and sources, mute microphones, play sounds, adjust system or per-app volume, launch apps and files, run macros, and build multi-step automations. Free for personal noncommercial use, local-first, with no ads or telemetry. Available for Windows 10 and 11.

Hi Product Hunt! I started building StreamNumDeck after I began streaming games and wanted tactile controls without buying more hardware. I only needed quick access to OBS scenes, microphone mute, replay buffer, sound effects, and a few system actions, but the tools I tried either relied on a phone or tablet or did not combine OBS, Windows audio, and macros in a way that felt simple. The unused numpad on my keyboard became the obvious hardware. Num Lock selects between two independent layers, so the numpad plus six navigation keys provide up to 44 actions per profile. Over time I added profiles, custom icons, per-app volume, an always-on-top microphone mute indicator, keyboard macros, and multi-step automations. StreamNumDeck is a Windows app with no ads or telemetry. Settings stay on the computer, and the OBS password is stored in Windows Password Vault. The source code is publicly available on GitHub, and both Setup and portable ZIP builds are offered. This is an early public release, and I would especially appreciate feedback about game compatibility, keyboard layouts, OBS workflows, and actions you would like to add. Thanks for taking a look!

Finally something that uses my neglected numpad instead of letting it collect dust. The num-lock layer toggle is genuinely clever, and OBS control feels way faster than fiddling with hotkeys.

finally something that uses my numpad for more than spreadsheets, the layer switching via num lock is honestly pretty slick. setup was straightforward and no telemetry nonsense is a huge plus.
