What We Actually Use

For our coding stack, we typically lean on GitHub Copilot for its real-time suggestions and Tabnine for personalized completions. We also incorporate ChatGPT for quick questions and DeepCode for security checks. This combination keeps our monthly costs around $50, leaving room for a couple of pro features from tools like Codeium or Sourcery.

Conclusion

Starting with a robust coding stack doesn’t have to be expensive. By leveraging the right AI tools, you can enhance your development process while keeping costs manageable. If you’re just getting started, I recommend beginning with GitHub Copilot and Tabnine, as they provide a solid foundation for most indie developers.
