Original: Vibe Coding vs. Spec Coding: How Kiro is changing the way we build AI-Powered Software
Short summary
The article contrasts 'vibe coding' (informal prompt-driven development) with 'spec coding' via AWS Kiro, which requires explicit functional and non-functional requirements before code generation. Vibe coding excels for MVPs and experimentation but loses coherence as projects grow. Spec coding forces upfront design documentation, making AI-generated codebases maintainable over time.
- •Vibe coding generates code from informal prompts but loses project coherence as complexity grows
- •Spec coding via AWS Kiro requires explicit requirements and architecture before code generation
- •Spec coding approach keeps design decisions documented and maintainable rather than hidden in chat history
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
