1. What Is Vibecoding?

• Vibecoding is the approach of giving instructions to coding agents in natural language and generating desired outputs.
• Users provide simple feedback like "I like this" or "this isn't great," and the agent modifies the work accordingly.
• "Vibecoding enables people without technical backgrounds to build things through code."
• Both technical and non-technical people are using vibecoding, particularly the approach of generating, modifying, and deploying code through LLMs (Large Language Models).

2. Key Characteristics of Vibecoding

(1) How Technical and Non-Technical Users Use It

• Technical users: Moving beyond writing code from scratch to describing desired features to LLMs, generating code, then modifying and deploying.
• Non-technical users: Creating apps or websites through vibecoding without any coding experience.
  • Example: Starting with a simple request like "Make me an app that tracks whether my dog has been fed."
  • "We're now in an era where people without technical backgrounds can create their own custom software."

(2) Vibecoding's Scalability

• Vibecoding goes beyond simple static website creation to enable dynamic web application development.
• Example: Building an app where users enter books they liked, it calls the OpenAI API to provide recommendations, stores results in a database, and includes Google authentication for login.
  • "We can now build true dynamic web applications, not just simple websites."

3. Key Tools and Companies Supporting Vibecoding

(1) Key Tools

• Cursor: An IDE-based tool for developers that assists in writing and modifying code.
• Replit, Bolt, Lovable, Vzer: Text-based web application creation tools for both non-technical and technical users.
  • "They offer an intuitive UI with a prompt window on the left and the generated interface on the right."

(2) Company Growth

• Some companies achieved millions of dollars in ARR (Annual Recurring Revenue) within months of launch.
  • Example: Bolt and Lovable each reached 10-20M ARR within just 2 months.
  • "Demand for these tools is enormous, especially providing great value to people building something for the first time."

4. Technical Foundations of Vibecoding

(1) Why Is Vibecoding Possible Now?

• LLM advances: Transformer architecture and vast data (especially web frameworks and JavaScript-related data) have significantly improved model performance.
  • "Since most modern apps are JavaScript-based, LLMs are very proficient at generating these apps."
• Mature web development environment: Full-stack apps based on JavaScript and TypeScript have become mainstream, making it easier for agents to verify and execute code.

(2) How Vibecoding Works

• Code generation and execution environment:
  • LLMs generate code based on user prompts.
  • Browser or server execution environments provide preview of results.
  • Various components like databases, authentication, and caching can be integrated.
  • "You no longer need to build a payment system like Stripe from scratch — just add it as a component."

5. Limitations and Areas for Improvement

(1) Current Limitations

• Issues with complex apps:
  • As apps grow larger, generated code may conflict with existing code or break certain features.
  • "Adding one design element often breaks the authentication feature."
• LLM over-optimism:
  • "AI always says 'I can solve this now!' but on the 40th attempt, the problem still isn't fixed."

(2) Improvement Directions

• State management:
  • Better systems needed for managing state across authentication, databases, and caching.
• Code verification:
  • Strengthening test coverage and code correctness verification.
  • "The next step is verifying that generated code actually works correctly."

6. Vibecoding Use Cases

(1) Individual Users

• "App for One": Creating personalized custom apps.
  • Examples: Plant watering tracker app, custom fairy tale generator for kids.
  • "You can now easily build apps for just one person."

(2) Small Businesses

• Marketing agencies and freelancers completing projects faster and cheaper.
  • Example: Projects in the $1,000-$2,000 range are now economically feasible.
  • "More people are using vibecoding tools instead of Squarespace or Wix."

(3) Enterprise

• Technical users leverage tools like Cursor for more complex projects.
  • "Enterprises are also boosting productivity through vibecoding tools."

7. The Future of Vibecoding

(1) Tool Evolution

• User segmentation: Tools will become more specialized by skill level.
  • Example: Simple app creation tools for non-technical users vs. advanced prototyping tools for engineers.
• Design integration: Adding fine-grained design controls like Figma.
  • "Text prompts alone have limitations, so more intuitive design tools are needed."

(2) New Interfaces

• Diverse prompt methods:
  • Beyond text, using screenshots, images, and personal data as prompts.
  • "Upload a screenshot of my Instagram page and make me a website that matches this vibe!"

(3) Pricing Models

• Currently usage-based pricing (per token) dominates.
  • But value-based pricing is possible.
  • "An e-commerce site generating millions in revenue and a personal webpage should be priced differently."

8. The Significance of Vibecoding

• "We've entered an era where not just the less than 1% of the population who can code, but anyone can build something through code."
• Vibecoding goes beyond making coding easier — it's a tool that enables more people to participate in creation.
• More tools and features will continue to emerge, and personal custom software creation like "App for One" will become increasingly mainstream.

"Vibecoding isn't just a technological innovation — it's an important tool leading the democratization of creation."
