We've gotten questions about Streamlabs OBS support and how this application compares to the free Streamlabs Remote Control. I'm happy to announce that we have implemented support for Streamlabs OBS and a version having this built-in is on its way out, as soon as we test it a bit more. It is still beta functionality so there may be issues, but it is there.
Do note that Streamlabs OBS doesn't support some features that OBS Studio has, so not all functionality is equal. Mostly it is the same and for your convenience the same buttons work for both OBS Studio and Streamlabs OBS, unlike with Elgato Stream Deck.
As for comparison to Streamlabs Remote Control, we can say that you get what you pay for. It's a convenient tool if all you need is to mute/unmute, switch scenes and hide/show items on screen. If you don't need macros, editable button order, volume control, fades, animations, connections to other services etc it might be ok for you. It's free so you can just try it out. But in the end, if you want something that provides good value for your streaming experience and doesn't make you hunt for the button you want to press, you know what to get for yourself.
Note that at the moment some features, like filling the Source lists is not working but it will be added soon.
