When to use each
- Claude Code — Complex refactoring, multi-file changes, CI/CD integration
- Cursor — Daily coding with visual diff, inline completions
- Cline — VS Code users who want agent capabilities without switching IDE
Pro tip: Use all three
With Izzi API, one API key works across all tools. Use Claude Code for heavy tasks, Cursor for daily coding, and Cline for quick edits — all drawing from the same balance.
