A third-party host is someone who runs BitcartCC instance and enables registration for other users. They might be free (but could accept donations) or with paid access.
Sometimes it's hard for users to deploy a new instance, but they want to try right away. That's what third-party hosts are for.
In general, it's not recommended to use them especially if you plan to scale your business, but it's great for testing.
Our demo at https://admin.bitcartcc.com showcases all coins BitcartCC supports, but we don't recommend using it for commercial purposes.
There are some hosts ran by others
You can contact us in one of our communities. Your server should have enabled server registration in server management settings.

Well, in most cases yes, but you should be aware of scams! People might fork BitcartCC and customize it to be malicious. We never intercept the payment process and never require a private key (except for lightning network). Also, watch your wallet to check if the host replaced your public key with their own! Some public hosts also handle a lot of customers of different services, so if you self-host one yours won't be that loaded.
