I have considered it and I was actually thinking to put more emphasis of it. The thing I'm mostly worried about "hosted" versions is centralization. To avoid this, I do provide a managed alternative, where I create, host and maintain your VPS. This way, each installation is done on its own server and there is no direct way to easily aggregate data from multiple users.
Fun fact, the "Hosting" page was actually one of the three buttons in the navbar (Features, Hosting, Pricing), but I replaced Hosting with Demo as the way I'm marketing userTrack only attracted customers that wanted either the self-hosted version or the agency one (them being the one providing the hosted userTrack for others).
Maybe consider making an AMI for sale via AWS. You can continue to get revenue via Aws hourly while the setup of the platform is easier in the case of the person above.
I did look over it at some point, as kept searching for the best way to allow users to install userTrack. I don't recall exactly why I didn't go forward with it, but I will have another look as they seem to allow paid products.
One problem I kept encountering while searching for platforms to distribute on was that most platforms only provide one-click installs for open-source software, not for premium software.
That being said, many non-techincal users have trouble using the not-amazing interface of AWS, this is why I ended up recommending DigitalOcean, as their interface is one of the best and using the cloud-init script you can deploy a server just by clicking some buttons, also the pricing structure is easier to understand.
