A comprehensive guide to picking the right AI coding assistant when you are a team of one. We tested Claude Code, Cursor, GitHub Copilot, Windsurf, Replit Agent, and v0 across real solo developer workflows.
Best for deep repo work and terminal-first developers
Runner UpBest IDE experience for VS Code migrants
Best for quick autocomplete inside any IDE
