Although the site works with a credit basis, you can get daily bonuses of 30 credits per day (1 credit = 1 image). Problem is that most of the things you would want to use is locked behind a subscription, so you have a rather limited toolset. The images it generates is pretty good, though some can be horrific abominations, very rarely you can make something that is nearly flaw free. You just have to know how to use prompts.

It's not free, it forces you to input an email before shoving a price tag in your face.
