SaaS/web app idea review

You tell me your app idea and I give you a developer's honest take: is it technically feasible solo? What's the right stack? What are the hidden complexity traps? What should you build first?

I'm currently building a SaaS product solo I know what it actually takes, what mistakes to avoid, and how to scope an MVP so you don't spend 6 months on something nobody wants.

Perfect for: developers with a side project idea, entrepreneurs who want a technical co-founder perspective, or students planning their first real project.
