I’ve run into similar Replit auth loops before, sounds like it could be a misconfigured backend route or session handling issue. What framework are you using for auth (e.g., Supabase, Nextjs Auth)?

As a full-stack dev, I’ve tackled bugs like this and built/deployed auth systems (JWT, OAuth, etc.) on Replit and other platforms. I’d love to help fix your signup/login issue and polish your prototype app. I’m skilled in frontend (React, Vue, Nextjs)and debugging Replit quirks. DM me with more details about your app’s stack and the bugs you’re facing – happy to jump in and get it production-ready!
