I use GOAFFPRO for collaborating with brands on their affiliate programs. It helps me track my commissions and the sales I made. It's really easy for tracking links and promo codes and seeing how many people used my code. I'd say the interface is really simple and easy to figure out too. The initial setup was very easy.

The only thing I don't like is that it doesn't have a section where you can find out what brands are on the platform to apply to the programs directly. Review collected by and hosted on G2.com.
