Introducing Spec Coding
Stop vibe coding. Define your specifications first, then let AI build production-ready code.
No upfront planning
Start coding immediately and figure it out as you go
Evolving requirements
Requirements change constantly during development
Frequent rewrites
Pivots and rewrites as understanding grows
AI guesses intent
AI tries to interpret vague instructions
Specifications first
Define exactly what you want before writing code
Clear requirements
Crystal clear requirements from day one
Predictable iterations
Iterate confidently with structured changes
AI knows exactly
AI understands precisely what to build
Precise Output
AI generates code that matches your exact requirements. No guessing.
Faster Development
Clear specs mean fewer iterations. Build the right thing the first time.
Easy Iterations
Update your specs, regenerate code. Changes are predictable and consistent.
How Spec Coding Works
A structured approach that transforms your ideas into production-ready code.
Better Architecture
Thinking through specs first leads to better structured, more maintainable code.
Reduced Risk
Validate your ideas in specifications before investing time in development.
