Kiro vs GitHub Copilot: Which AI Coding Assistant Wins for React Development?

July 28, 2025 Lothar Schulz 0

I tested Kiro’s structured, spec-driven development approach against GitHub Copilot’s rapid iteration style by building the same React quiz app with both tools. While Kiro excelled at upfront planning and task breakdown, its rigid methodology failed to produce working code. Copilot’s pragmatic approach with real-time feedback ultimately delivered a functional prototype. The key insight? Understanding when to use structured planning versus rapid prototyping can make or break your AI-assisted development workflow.
