Creating an app could take months or even years of work in the not-so-distant past. However, now all that is replaced with just a few hours of “vibe coding”. An indie developer, Pieter Levels, built a viral flight simulator using Cursor in 3 hours. He created the simulator using simple natural-language prompts, which generated $57,000 per month for him.
Recent AI advancements have made app creation accessible and conversational for non-programmers. The key is “vibe coding”, which lets users build apps and websites with simple natural language prompts instead of writing traditional code. That’s what we will learn in this guide. So, stick around to learn how to create an app with Vibe coding in a day with a complete step-by-step process.
What Is Vibe Coding? A Quick Overview
OpenAI co-founder Andrej Karpathy coined the term “vibe coding” in an X post to describe a new way of building software in which developers can “forget that the code even exists.” Vibe coding is an AI-assisted software development approach that generates functional code from natural language prompts.
It switches the user’s role from writing code to guiding an AI assistant. You provide high-level descriptions of features and logic, and the AI handles the implementation. For example, you can instruct the AI to “build a weather dashboard that shows the current temperature and a 5-day forecast for a user-entered city,” and it would generate the code for the user interface, API integration, and data display.
However, don’t think that vibe coding eliminates the need for a developer’s mind. It redirects the mind from syntax to architecture/problem-solving and user experience. Choose the Platform to Vibe Code The first step in creating an app with Vibe Coding is choosing the platform. You now have many top vibe coding platforms to choose from in 2026:
- Replit — Best for rapid prototyping and publishing a complete app from a browser.
- Cursor — Shines in AI code editing and autocompletion for professional developers refining complex projects.
- Lovable — Best for non-coders and founders to build full-stack web applications and MVPs.
- Google AI Studio — Best for the fastest path to build a shareable web app prototype with one-click deployment.
You can choose the platform that you like. We will use Replit for this guide to create a functional app with just vibe coding.
Phase 1: Morning Foundation (Ideation + MVP)
Step 1. Ideation and Prompt Crafting
Start the day with ideation and prompt crafting. Your first prompt is the most important. Don’t just say “build a to-do list app”.
Be more outcome-focused:
- The Core Problem: “I need a personal habit tracker to improve my consistency.”
- Key Features: “It should let users add habits, mark them complete daily, and show a weekly streak calendar.”
- Tech Preferences (Optional): “Use a React-based frontend and a simple file-based backend for ease.”
Good prompts combine vision with practical constraints to give the AI a clear blueprint.
Step 2. Generate the MVP
Go to Replit, sign up, and input your prompt. The AI will begin the background coding stuff and generate all the project structure, core files, app interfaces, etc. Wait for it to complete and then test the app.
The first run may not be perfect, but you should see a working interface. Check the core data flow: Can you add a habit? Does the UI update?
Phase 2: Afternoon Iteration (Debugging + Features Enhancement)
Step 3. Debug the Hurdles
If you encounter an error, copy the exact error message and the relevant code snippet. Afterward, provide this specific context back to your AI assistant with a clear instruction to analyze and fix the issue.
Step 4. Add More Features
Once the debugging part is completed, move on to enhance your app with follow-up prompts:
- “Add a dark mode toggle that switches the theme.”
- “Create a chart on the dashboard showing my completion rate over the last 30 days.”
- “Let users categorize habits, such as Health, Work, Personal, etc.”
Work on one feature at a time and commit your progress along the way.
Step 5. Styling and Polish
Direct the AI to improve the user experience, such as “Make the button colors more accessible and add subtle hover animations.”
Phase 3: Evening Deployment & Review (Deployment + Security Checks)
Step 6. Prepare for Deployment
Now, let the AI handle deployment. For example, you can use the built-in “Publish” button to publish the app. Once done, it will provide you with a web link to access and share the app.
Alternatively, you can ask the AI to “Create a GitHub Actions workflow to deploy this to GitHub Pages”. The AI can generate proper configuration files (like firebase.json or GitHub Actions YAML). Also, ensure any API keys are stored in environment secrets.
Step 7. Final Security and Logic Review
Conduct a final review before going live. This is critical because AI can introduce significant security vulnerabilities and logic flaws into the generated code. A final human-led review is essential to catch these issues before the app goes live.

That’s how you can create an app with Vibe coding in a few hours. All it requires is providing clear, detailed prompts, then watching the AI handle the hard part.
Best Tips for Vibe Coding
Now that you know how to create an app with Vibe coding, let’s quickly take a look at useful tips related to prompt-based coding:
- Detailed Prompts: You are directing a talented but literal-minded AI “team”. Provide clear objectives and context, and be specific about features and user actions.
- Embrace Iteration: Your first prompt creates version 0.1. Be prepared for several refinement cycles.
- Provide Rich Context: When stuck, give the AI the error message, relevant code snippets, and a description of what you were trying to achieve.
- Know When to Step In: AI can hallucinate libraries or overcomplicate solutions. Use your judgment to move toward more standard approaches.
Moving forward in 2026 with Vibe Coding
In 2026, your idea doesn’t need to wait for a development team or months of work. The right platform and a day focused on conversational building can turn your idea into a running app. That’s why searches for vibe coding grew 6,700% in 2025, and 92% of US developers now use AI coding tools daily.
