My Recommendations
Beginners: GitHub Copilot. Easiest to start, free tier is enough, native VS Code.
IDE users: Cursor. Best multi-file editing, 50 free completions for testing.
Terminal users: Aider or OpenCode. Aider for Git-first workflows, OpenCode for open-source fans.
Privacy-first: Continue + Ollama local models. Data never leaves your machine.
Large projects: Claude Code. 1M context window understands entire codebases, but paid.
Budget-conscious: Codeium or Windsurf. Free personal tiers, sufficient features.
Summary
No perfect tool, only the one that fits you. Pick based on your workflow, budget, and privacy needs. Don’t chase the latest hype.
Tools are just tools. You’re still the one writing code.
