Wow, this is pretty upsetting because I have been working on the exact same idea as you. How long has it been up, what kind of volume have you been doing, and how long did it take you to make it?
Yeah, we initially built it a few months ago to solve a need we had internally. Didn't see any easy way to do simple A/B testing so we decided to build it since we figured it might be useful to other people too. Haven't done much marketing for it yet, but glad to hear there's interest for it. Some awesome feedback here too.
