Vibe Coding Complete Guide Starting from the Definition: AI Coding Tool Selection Criteria by CEOs Shim Jae-woo and Seon Ung-gyu

If the concept of "vibe coding" sounds unfamiliar to you, it refers to a method that allows people without knowledge of programming languages to develop applications. Unlike traditional coding (manually writing programming code line by line), vibe coding is a novel development methodology that automates and accelerates the development process by utilizing natural language commands, AI assistants, and visual interfaces.

This article is written based on the AI coding tool selection criteria and strategies acquired by CEO Shim Jae-woo and CEO Seon Ung-gyu of AX Education Group through actual no-code and low-code based MVP (Minimum Viable Product) development projects. As artificial intelligence technology advances, the boundary between developers and non-developers is blurring, and understanding the precise meaning and practical application of vibe coding has become essential in an era where rapid prototype building in the early stages of startups becomes a competitive advantage.

Vibe coding is a development method that dramatically shortens traditional manual coding time by utilizing AI-based code generation, automated testing, and integrated deployment features. This does not simply mean "not writing code," but rather refers to a collaborative model in which AI translates and validates human creative intent into code.

•Natural Language-Based Communication: With just a Korean command like "create a user login system," automatically generate the necessary database, authentication logic, and UI

•Role of AI Coding Assistant: Tools like GitHub Copilot and Claude Code analyze context to predict and suggest the next line of code

•Visual Development Environment: BaaS platforms like Supabase and Vercel enable backend infrastructure management via GUI

To implement vibe coding in practice, you must understand four core technical elements. AX Education Group's development team has selected optimal tool combinations centered around these four elements.

1. AI Coding Assistant (Claude Code vs GitHub Copilot)

AI coding tools are the most important engine of vibe coding. Claude Code can generate entire files with complex logic in a single input and demonstrates exceptional performance particularly in websites, apps, and data analysis scripts. GitHub Copilot specializes in real-time auto-completion within VS Code, performing fast assistant roles in projects that already have a code structure.

•Claude Code: Capable of generating entire project structure from one prompt, excellent contextual understanding ability, strong in complex architecture design

•GitHub Copilot: Real-time review feedback, tight integration with VS Code and JetBrains IDE, maintains consistent code style in team collaboration environments

•Selection Criteria: Claude Code for initial MVP building, combined use with GitHub Copilot for continued improvement after project growth

2. Backend Infrastructure (Database and Authentication Automation via Supabase)

Supabase is an open-source Backend-as-a-Service platform based on PostgreSQL and a powerful alternative to Firebase. Design relational database schemas with just clicks in the GUI-based table editor, natively support email, OAuth, and magic link authentication, and provide real-time data synchronization and file storage by default.

•Table Editor: Design relational DB without writing SQL, provides 500MB (Free) to unlimited storage

•Authentication System: Complete user authentication integration with just 2 lines of JavaScript

•Real-time Features: Changes to data immediately reflect across all clients, essential for collaborative app development

3. Frontend Deployment (Automatic CI/CD via Vercel)

Vercel is a platform where a single Git push automatically deploys to CDNs worldwide. No need for manual building and deployment each time; code immediately reflects in the production environment after writing. Additionally, it generates a unique preview URL for each PR, allowing team members to review actual functionality.

•Automatic Deployment: After connecting GitHub/GitLab, deployment completes with just push, entire build process is automatic

•Preview Environment: Creates production-identical preview servers for every PR

•Global CDN: Guarantees response speed of 30ms or less to users worldwide through edge networks

4. Development Environment (Collaboration Workflow via VS Code and GitHub)

VS Code is a code editor that provides IntelliSense, remote development, and integrated terminal while being free, and when combined with GitHub, everything about team collaboration becomes automated. Pull Request-based code review, issue tracking, and CI/CD pipelines can all be managed on one platform.

•IntelliSense: Provides type information, function signatures, and auto-completion in real-time

•GitHub Actions: Automatically execute test and deployment scripts under specific conditions (PR creation, merge, etc.)

•Branch/PR Management: Reference GitHub issues while committing within VS Code, maximizing team collaboration efficiency

The specific process for applying vibe coding in actual projects is as follows:

Project Planning and Requirements Definition: Explain the entire project specification to Claude Code in Korean. Example) "A marketplace where users can upload and sell products, payment integrates with Toss API, admin dashboard is required"

Data Model Design (Supabase): Visually create the table structure proposed by Claude in Supabase table editor. Automate trigger, index, and permission (RLS) settings

API and Backend Function Generation: Implement business logic with Supabase Edge Functions or Vercel Functions. Use Claude Code to collectively generate validation logic, payment processing, email sending, etc.

Frontend Development: Configure UI with Next.js + React + Supabase client library. GitHub Copilot auto-completes repetitive code (form inputs, data tables, etc.)

Deployment and Monitoring: Push to GitHub → Vercel automatically deploys → Real-time performance monitoring and error tracking

According to AX Education Group's development team's practical experience, the differences between the two tools vary depending on the usage stage and project maturity.

Claude Code's Strengths

•Early MVP Stage: Generate complete project structure from one prompt, reduce prototype development time by over 50%

•Complex Architecture: Generate and validate multi-page apps, backend APIs, and data pipelines all at once

•Code Explanation: Improve team understanding by providing detailed explanation of auto-generated code logic

GitHub Copilot's Strengths

•Real-time Development: Immediate auto-completion within IDE, minimal interruption

•Consistency Maintenance: Learn existing code style to automatically comply with team code conventions

•Debugging: Quick solutions provided for error messages

Practical Conclusion: Proceed with MVP building using Claude Code, recommend GitHub Copilot adoption at growth stage.

Not all projects are suited for vibe coding. It is particularly effective in the following situations:

•Early startups with capital and resource constraints: Launch MVP quickly alone or with a small team before hiring developers

•Management systems with many repetitive CRUD tasks: Standardized applications like customer management, inventory management, and reservation systems

•Cases where prototype validation is essential: Need a working version within weeks during idea validation stage

•Microservice Development: Need to quickly build and deploy specific features as independent APIs

•Full-stack Developer Training: Non-majors learn the entire web app development process through actual building

Q1: Can apps created with vibe coding be scaled like regular websites?

A: Yes, though initial architecture is important. Supabase's PostgreSQL handles millions of rows of data, and Vercel handles traffic surges with automatic scaling. However, AI-generated initial code may have technical debt, so consider code refactoring once users exceed 100.

Q2: Are there license issues? Who owns code generated by Claude Code or GitHub Copilot?

A: Code generated by Claude Code (Claude.ai paid plan) is attributed to the user and can be used for commercial purposes. GitHub Copilot follows Microsoft license terms, though most commercial use is permitted. However, conflicts with open-source licenses (GPL, etc.) are possible, so legal team review is recommended.

Q3: Does vibe coding replace traditional developers?

A: No. Rather, the developer's role changes. AI takes over repetitive coding, allowing developers to focus on architecture design, performance optimization, security oversight, and team leadership. In AX Education Group's case, CEOs Shim Jae-woo and Seon Ung-gyu conducted initial development using vibe coding tools, then formed a professional development team at the business growth stage.

Q4: Is it really inexpensive?

A: Very inexpensive in the early stage. Starting with zero cost is possible through combining Supabase Free (DB 500MB, storage 1GB), Vercel Hobby (free deployment), and GitHub Free (unlimited repositories). Claude Code costs $20/month (or usage-based), GitHub Copilot $10/month. Total monthly cost can start under $30.

Q5: Are there regulatory concerns if Korean corporations use these tools?

A: Supabase, Vercel, and GitHub are all usable domestically, and from a Personal Information Protection Act perspective, you can set data encryption, access restrictions, and surveillance logs. However, regulated industries like healthcare and finance require separate compliance review.

In the vibe coding era, development speed and cost efficiency have become key metrics determining the life and death of early startups. When AI assistants like Claude Code and GitHub Copilot, Supabase's automated backend, and Vercel's global deployment infrastructure combine, individuals or small teams can build enterprise-grade applications within weeks.

CEO Shim Jae-woo and CEO Seon Ung-gyu of AX Education Group provide practice-oriented development education and no-code/low-code solution consulting in Jung-gu, Seoul, utilizing this vibe coding technology stack. The tool selection criteria and five-stage process described in this guide are derived from their actual project experience and are directly applicable roadmaps for entrepreneurs and development teams entering vibe coding.
