In the fast-paced world of indie hacking and side projects, getting functional code up and running quickly can be a game-changer. Imagine needing a feature for your MVP and being able to generate it in less than two hours. Sounds too good to be true? Well, with the right AI coding tools, it’s not only possible but achievable. In this guide, I’ll walk you through the best tools to help you generate functional code efficiently, along with pricing, limitations, and our honest take based on real experiences.

Time Estimate: 2 Hours

You can finish generating basic functional code in about 2 hours if you follow the steps I outline here.

Prerequisites

• Basic understanding of programming concepts
• An account on the AI coding tool of your choice
• A coding environment (like VS Code, Replit, etc.) set up for testing your code
