In this video, I evaluate the new Claude Sonnet 4.5 by putting it to the test: building a complete Micro-SaaS web app from zero to a live, functioning product in just a few hours. I take you through the entire process, starting with a free starter kit and setting up a production-ready environment using a Hostinger VPS and EasyPanel for the database.
From there, I configure Google OAuth for authentication and integrate Stripe for a token-based payment system, using the Claude Code extension in VS Code to write and debug code in real-time. The final result is a simple AI logo generator, and I show every step, including the inevitable errors and how I used Claude 4.5's incredible speed to fix them and get the app working.
