AI FreeCode Service™ Generates 680,000 Lines in 15 Minutes: Accelerating Enterprise Development Beyond 'Vibe Coding'

Wonderful Fly Inc. (Chuo-ku, Tokyo) is proud to announce that its AI-driven automated programming service, 'AI FreeCode Service™', can now generate approximately 680,000 steps of code from design specifications in just 15 minutes.

This service significantly accelerates the traditional development process by having AI analyze and generate entire business systems—including screens, business logic, databases, and reports—based on design information.

### Background: Why is Development So Burdensome? As companies push for digital transformation (DX), they face severe challenges: lack of engineers, rising outsourcing costs, rework due to requirement changes, and long development timelines. Large-scale systems with hundreds of thousands of lines often require massive man-months, leading to a gap where business environments change before the system is even complete.

### Innovation: 680,000 Steps in 15 Minutes AI FreeCode Service™ uses design documents (such as Excel) as input. The AI analyzes the entire system structure and automatically generates all components—screens, DB definitions, logic, and reports—simultaneously. Notably, it can produce 680,000 steps in just 15 minutes.

While traditional development of this scale would typically require around 150 man-months of resources and months or years of time, AI FreeCode Service™ achieves this at near real-time speeds. It shifts the paradigm from 'human-driven manual labor' to 'structurally AI-assisted construction.'

### AI Coding and the Rise of Vibe Coding Recently, 'Vibe Coding'—generating code through natural language prompts—has gained attention for rapid prototyping and small apps. However, enterprise systems require more than just quick snippets; they need consistency across logic, databases, and maintainability.

AI FreeCode Service™ applies AI coding specifically to these complex enterprise needs. Unlike Vibe Coding, which relies on subjective prompts, this service uses design documents as the benchmark. This ensures the reasoning behind the specifications is clear, making the resulting systems easier to maintain and modify. It is an evolution of AI coding into a 'design-driven automated program generation service' for the corporate world.
