Hello !
I was looking for a tool to engage my community during live events and hesitated between several tools before going to Onlive. Let me share my reasons if it can help :)

+ end to end management : having a tool which covers everything from the registration to the streaming and the animation is quite unique
+ studio is really impressive : the capability to change in a single click the screen organisation is a game changer (OBS is not necessary after all...) and the way to add a guest on scene is really good ! Other goodpoint, th epossiblity to stream directly in the flow a recorded video (for example pause video or intro video) makes the result quite professional
+ all external pages are really well done (like the registration page with countdown for example) are clean an professionals

my only cons for now : "One moment, please...Thank you for being such a patient human." phrase which is not really fun in term of user experience to *prepare* the event. The backend interface is dawn slow... Don't prepare an event in a hurry. I hope they will improve on this point :)

one point of attention : the subdomain approach for the events. Unmanageable at short term if we want to avoit url like lkdjfkdsjkfldsqjkgfjdsqkljglkj.onlive.io . I hope a CNAME on tiers 1 at least (and several on other tiers...) or at least the possibility to reserve some (not only one) xxxxx.onlive.io and use folder like xxxxx.onlive.io/aaaa xxxxx.onlive.io/bbbb etc.

continue like this !
