Just out of curiosity, because I really do not know how this type of marketing works best. Is there not a a potential risk of users getting used to having it for free, and a potential advantage to introduce the idea of this being a paid product early?
We are growing it, but also starting to think about monetization. Luckily there are no server costs with Chrome Extensions. At the moment our only costs are the website and domain.
I thought the chrome extension rendered a website with an embedded youtube player.
The chrome extension contains all necessary assets locally, which then has the embedded video player in it. So no web host necessary, except for initial signups/explaining the product.
