Similar to what Gamewisp is, a place where you can set different subscription tiers with different rewards that you can set as a streamer.
Gamewisp is kind of unreliable for handling payments and their discord/support answers take weeks to reply.
It would be pretty good if the service has a way to show alerts on screen as well as to have a way to write a .txt file in your computer so that you can add a latest sub panel in your stream layout.
The reason for a tool like these being handy to multistreamers is because twitch affiliate program doesn’t allow to multistream and it would be nice to have an integrated solution for that.
