Not every tool is right for every developer. Here's a quick decision guide based on your situation:
If: You're a student or beginner
Start with GitHub Copilot (free via GitHub Education) + ChatGPT Free. These two tools alone will halve your learning time.
If: You want unlimited free completions
Codeium has zero usage caps on its free plan and works inside 40+ editors. No credit card required.
If: Privacy is your top concern
Tabnine's local mode runs entirely on your machine. No code ever leaves your environment.
If: You want a complete AI IDE
Try Cursor — it replaces VS Code entirely and lets you chat with your whole codebase in context.
If: You're building AI-powered apps
Stack AI lets you visually chain AI APIs together without complex backend code. Ideal for non-backend developers.
If: You want to self-host everything
CodeT5 is fully open-source and can run on your own hardware — ideal for teams with compliance requirements.
