As indie hackers, we often find ourselves juggling multiple roles—from product development to marketing. With the rapid evolution of AI coding tools, it’s easy to get lost in a sea of options that promise to make our lives easier. But as budget-conscious builders, we need tools that are not just effective but also affordable. This guide breaks down a practical AI coding tool stack that costs around $100/month, allowing you to maximize your productivity without breaking the bank.

The Essentials of an AI Coding Stack

1. Code Generation: OpenAI Codex
