Key Differences Explained
Development Philosophy
Kiro enforces a structured workflow: Requirements → Design → Tasks → Code. This spec-driven approach ensures you plan before coding, resulting in better architecture and fewer rewrites. The AI generates comprehensive specs that guide development.
Cursor offers more flexibility with its chat-based interface. You can ask the AI to make changes, explain code, or generate new features without following a rigid structure. This is faster for quick changes but may lead to less organized codebases.
AI Integration Depth
Kiro's AI is deeply integrated into every phase of development. It doesn't just write code – it creates requirements, designs systems, breaks down tasks, generates tests, and maintains documentation. The hooks system runs AI tasks automatically on events.
Cursor's AI is more of an intelligent assistant. It excels at understanding context across your entire codebase and can make sophisticated multi-file changes, but you need to explicitly ask for each action.
Team Collaboration
Kiro generates shareable spec documents that serve as a contract between team members. The structured approach ensures everyone understands the system design and requirements, making it ideal for team projects.
Cursor is more suited to individual developers or loose collaboration. While multiple people can use it on the same project, there's no built-in structure for coordinating AI-assisted development.
Our Recommendation
For new projects and teams: Choose Kiro for its structure and automation
For existing projects and solo devs: Choose Cursor for flexibility
For maximum productivity: Consider using both for different phases
