TheDegenerate$Lounge is completely free to use — every link here is a referral link. If you sign up or deposit through one, it doesn't cost you anything extra, but it does throw a little something my way, so using the app is basically your way of saying "nice site."
I built this for myself. Once you've signed up to a few of these places, you lose track fast — which ones you're actually registered on, which ones you've put money into, which ones you forgot even existed. I got tired of that mess, so I made this. The favourites section lets you pin the ones you actually use, so you're never digging through the list again.
