What is Vibe Coding and Why It Changes Everything

Vibe Coding is revolutionising software development. At Jump Online, it's the method we use daily to deliver business applications in 30 days instead of 6 months. But what exactly is it?

Defining Vibe Coding

Vibe Coding is a software development approach where the developer acts as architect and orchestrator rather than manual coder. Instead of writing every line of code by hand, the developer creates structured specifications that AI tools (Claude by Anthropic, Replit Agent, GitHub Copilot) translate into functional code. The term was popularised by Andrej Karpathy, co-founder of OpenAI, in early 2025.

How does it work in practice?

Our process breaks down into 5 steps:

1. Structured specification — We write a detailed specification describing every feature, every business rule, every interface.
2. AI generation — The AI translates these specifications into functional code (TypeScript, React, PostgreSQL).
3. Architecture review — We verify code quality, security and performance.
4. Iteration — The client tests, provides feedback, we adjust in real time.
5. Validation — Automated testing, deployment, user training.

The numbers speak for themselves

Here are the concrete results at Jump Online after 2 years of Vibe Coding:

• Delivery time: 30 days instead of 6 months (÷6). Source: internal Jump Online data from 54 projects.
• Cost reduction: 40 to 60% cheaper than traditional development. According to Forrester Research, AI-assisted development tools reduce costs by 30 to 50%.
• Satisfaction rate: 97% of our clients are satisfied with the final result.
• Average ROI: 240% over 12 months, measured across all our Valais clients.

Is the quality there?

This is the question everyone asks. The answer is yes, provided the developer is an experienced architect. AI is a powerful tool, but it doesn't replace human expertise in software architecture, security and user experience. According to GitHub, developers using AI assistants are 55% more productive.

The future of software development

Vibe Coding isn't a passing trend. According to Gartner, by 2028 75% of enterprise code will be AI-generated, compared to less than 10% in 2023. Companies adopting these methods now are gaining a competitive edge.
