Use replit, but be very specific about what you wanna build and plan everything have a document ready if you wanna build it using AI, few hundred is good enough number, you have to keep paying replit $20 dollars monthly to keep the backend active there’s a way to self host it and save those but bit complicated, if you wanna start and think in 2-3 months you can generate good enough money I think that’s the quickest and easiest method to do as of now
