Why Free AI Coding Tools Matter

GitHub Copilot ($10/month) and Cursor ($20/month) are powerful, but not every developer can or wants to pay monthly fees. Fortunately, several excellent free AI coding assistants have emerged that rival premium tools.

Tips for Maximizing Free Tools

  • Write descriptive comments to guide AI suggestions
  • Use meaningful variable and function names
  • Break complex tasks into smaller functions
  • Review all AI-generated code carefully
  • Combine multiple tools (e.g., Codeium + Continue.dev)

Conclusion

You don't need to pay $10-20/month for AI coding assistance. Codeium's free tier offers unlimited completions and rivals GitHub Copilot's capabilities. For most individual developers, it's the perfect choice.

If you need more control or privacy, explore Continue.dev with self-hosted models or TabNine Free for local processing.
