How to Choose

Ask yourself:

1. Where do you code? If you're in VS Code/JetBrains, Copilot or Cursor. If you're browser-based, PlayCode.
2. What do you build? Web apps → PlayCode or Copilot. AWS → CodeWhisperer. General → Copilot or Claude.
3. Privacy concerns? Tabnine for on-premise. Be aware that most cloud assistants send code to servers.
4. Budget? CodeWhisperer and Gemini have generous free tiers. Students get Copilot free.

The Verdict

For most developers: GitHub Copilot is the safe, proven choice. It just works.

For web developers:PlayCode AI offers the most models and a unique agent-based approach.

For complex debugging: Claude's reasoning capabilities are unmatched.
