Strong start , easy to use , very fast and responsive .

Suggestion/feedback : this being a launch . It might not be a good idea to limit people to 2 codes . The only thing this accomplishes, you user db will grow with people using their burner Gmail accounts. Sure is not ranking anywhere yet, so I m sure you guys get very small share of organic traffic . Let people add 5-10 codes, link to their user profile on their socials etc ... This would help with the the back links. SEO, and ranking ... Right now with 2 codes , I doubt you will make money with premium features and will slow down the potential for organic growth . Just my 2 cents from web developer/SEO perspective
