I Built 3 Web Apps Without Coding Using AI | Step by Step Guide

In this video, I test Hostinger Horizons by building 3 fully functional web apps without writing a single line of code — including a Time Tracking App, a Gaming Café Booking System with database integration, and a Professional Invoice Generator. Instead of just talking about AI website builders, I wanted to properly evaluate whether AI “vibe coding” can actually create usable, structured web applications for real-world use cases. Each app in this video was built through AI conversation — including UI design, logic handling, database connection, login system, and PDF generation.
