We Vibe Coded a $16k AI App. It was Amazing & Terrifying

Key Concepts

• Vibe Coding: Building applications and websites using AI coding tools with minimal to no traditional coding.
• PRD (Product Requirements Document): A detailed plan outlining the goals, features, and technical specifications of a project.
• LLM (Large Language Model): AI models like Gemini, Claude, and GPT used for code generation and problem-solving.
• MCP (Managed Code Plugin): Extensions that provide AI coding tools with access to specific documentation, APIs, or functionalities.
• Astro: A web framework for building fast, content-focused websites.
• Tailwind CSS: A utility-first CSS framework for styling web pages.
• Cloudflare: A web infrastructure and security company offering services like hosting, CDN, and bot protection.
• GitHub: A web-based platform for version control and collaboration using Git.

• Rate Limiting: Limiting the number of requests an API key can make within a certain timeframe to prevent abuse and control costs.

Brand Snap: A Case Study in Vibe Coding

• Overview: Brand Snap is a tool designed to help users find available domain names and social media handles for their businesses.
• Functionality:
  • Brainstorms domain names based on user input and desired TLDs (e.g., .com).
  • Checks domain name availability.
  • Scrapes social media platforms to check handle availability (Instagram, Twitter, Facebook, YouTube, etc.).
  • Brainstorms alternative social media handles if the desired ones are taken.
  • Calculates the "strength" of a brand based on domain and social media handle availability.
• Monetization: Affiliate links to SiteGround and Namecheap for domain registration.
• Cost Comparison: The original version, built by a developer, cost $16,270. The vibe-coded version was built in under a week.
• Challenges:
  • Securing the app against bots and malicious users.
  • Managing API costs.
  • Choosing the right APIs.
• "Tools are the new content": The idea that interactive tools offer more value than traditional text content in attracting and monetizing website traffic.

The Vibe Coding Process: A Step-by-Step Guide

1. PRD (Product Requirements Document) Creation:
   • Use an AI tool (Gemini, Claude, GPT) in "canvas" mode.
   • Instruct the AI to act as a project manager for a web app.
   • Thoroughly describe the project's goals, features, and technical requirements.
   • Research and select appropriate APIs for domain checking, social media scraping, etc.
   • Update the PRD with API information and other relevant details.
2. Code Editor Setup:
   • Install a code editor (e.g., Cursor, which has a free plan with AI features).
   • Create a new project folder in the code editor.
   • Open a terminal within the code editor.
3. Cloud Code Installation:
   • Install Cloud Code in the terminal using the command provided on the Cloud Code website.
   • Connect the Cloud Code account (paid plan recommended) or use an API key (not recommended due to cost).
   • Integrate Cloud Code with the code editor by typing /IDE in the Cloud Code terminal and selecting the editor.
4. MCP (Managed Code Plugin) Installation:
   • Explore available MCPs on sites like smissery.ai.
   • Install relevant MCPs (e.g., Context 7 for accessing web framework documentation).
   • Use the installation guides provided on the MCP's GitHub page.
   • Example: Install Context 7 using the provided command in the terminal.
5. Project Initialization:
   • Use the /init command in Cloud Code to analyze the existing code and create a project context.
6. Planning and Execution:
   • Use "plan mode" (shift+tab) to have Cloud Code create a detailed plan before writing any code.
   • Provide clear and specific prompts to guide the AI.
   • Use "think step by step" to trigger reasoning mode for better results.
   • Approve or reject steps in the plan based on your understanding of the project requirements.
   • Provide feedback and iterate on the plan as needed.
7. Building and Debugging:
   • Approve the plan to allow Cloud Code to execute the code.
   • Monitor the progress and provide feedback on the generated code.
   • Use the code editor's debugging tools to identify and fix errors.
   • Use plan mode to create a plan for fixing errors before implementing the fix.
8. Testing:
   • Use testing frameworks to write tests for different parts of the code.
   • Run the tests to ensure that the code is working correctly.
   • Use the test results to identify and fix any remaining errors.
9. Deployment:
   • Use Cloudflare Workers for free or low-cost hosting.
   • Install the Cloudflare Wrangler CLI tool.
   • Use Cloud Code to deploy the application to Cloudflare.
   • Connect Cloudflare to a GitHub repository for automatic deployments on code changes.
10. Security:
    • Store API keys securely using environment variables on the hosting platform.
    • Use rate limiting to prevent abuse and control costs.
    • Implement bot protection measures (e.g., Cloudflare Turnstile).
    • Use code analysis tools (e.g., Code Rabbit) to identify security vulnerabilities.

Limitations and Security Issues

• Security Risks: AI-generated code can contain security vulnerabilities if not properly vetted.
• API Abuse: Bots can drain API credits and lead to unexpected costs.
• Rate Limiting: Essential for preventing abuse and controlling API costs.
• Secure API Key Storage: API keys should never be stored directly in the code; use environment variables.
• Cloudflare Features: Utilize Cloudflare's bot protection, rate limiting, and other security features.
• Code Analysis Tools: Use tools like Code Rabbit to identify and fix security vulnerabilities in AI-generated code.

Examples and Tools

• Cursor: A code editor with free AI features.
• Cloud Code: An AI coding tool that integrates with code editors and provides access to various MCPs.
• Gemini, Claude, GPT: Large language models used for code generation and problem-solving.
• Context 7: An MCP that provides access to web framework documentation.
• Code Rabbit: A code analysis tool that identifies security vulnerabilities in AI-generated code.
• Cloudflare Turnstile: A CAPTCHA alternative for bot protection.
• Astro: A web framework for building fast, content-focused websites.
• Tailwind CSS: A utility-first CSS framework for styling web pages.

Key Arguments and Perspectives

• Vibe coding is powerful but challenging: It enables non-coders to build applications but requires careful planning, security measures, and debugging.
• Planning is crucial: Spending time on the PRD and planning phase can save significant time and effort in the long run.
• AI is not a replacement for developers (yet): AI can automate many tasks but still requires human oversight, feedback, and debugging.
• Security is paramount: AI-generated code can introduce security vulnerabilities, so it's essential to implement robust security measures.
• Tools are the new content: Interactive tools offer more value than traditional text content in attracting and monetizing website traffic.

Notable Quotes

• "The truth is I got it working in one day. It was working in one day. But because this is kind of like an app on the internet where people can just input anything they want in that box and by just going on the domain like as soon as I put it online there was like literally hordes of bots trying to spam this etc. And so I spent most of my time securing this app versus actually building it." - Gail
• "Tools are the new content." - Gail, referring to the idea that interactive tools offer more value than traditional text content.
• "Don't do it if you're not willing to learn properly." - Gail, emphasizing the importance of learning and understanding the underlying technologies.

Synthesis/Conclusion

Vibe coding represents a significant shift in software development, enabling individuals with limited coding experience to build functional applications. While AI coding tools like Cloud Code can automate many tasks, they require careful planning, security considerations, and human oversight. The process involves creating a detailed PRD, setting up a code editor and AI coding environment, installing relevant MCPs, and iteratively planning, building, debugging, and testing the application. Security is paramount, and developers must implement measures to prevent API abuse, protect API keys, and identify security vulnerabilities in AI-generated code. While vibe coding is not a replacement for traditional development, it offers a powerful new approach for building tools and applications, particularly for small businesses and individuals who are willing to invest the time and effort to learn the process.
