Built this after rebuilding the same auth + payments + email stack for the 5th time. Figured other devs might be tired of it too. Sushify is everything I wish existed when I started – production-ready from day one, not "production-ready after you fix 50 bugs." Happy to answer any questions about the stack or implementation!
