Vibe Coding: How to Build a SaaS in 60 Minutes (No Typing Required)

by

The “10x Developer” is dead. Long live the “100x Director.” 🎬

In late 2025, a new term took over Twitter/X: “Vibe Coding.”

It describes a state of flow where you aren’t fighting with syntax, semicolons, or CSS centering. Instead, you are vibing with the AI—managing the logic, directing the flow, and letting the models write the boilerplate.

Today, we are doing a SaaS Speedrun. We will build a fully functional Micro-SaaS (an AI Resume Roaster) in under one hour.

🚫 No manual CSS writing. 🚫 No wrestling with database configs. ✅ 100% Natural Language.

🛠️ The “God Mode” Tech Stack

To move this fast, we need tools that speak AI natively.

  • 🧠 The Brain: Cursor (The AI Code Editor).
  • 🏗️ The Framework: Next.js 15 (App Router + Server Actions).
  • 🎨 The Designer: v0 by Vercel (Generative UI).
  • ⚡ The Backend: Supabase (Postgres + Auth).

⏱️ Minute 0-10: The Setup

Open your terminal. We aren’t starting from scratch; we are starting from excellence.

  1. Initialize the Project: npx create-next-app@latest my-saas-app --typescript --tailwind --eslint
  2. Open in Cursor: Forget VS Code. Open this folder in Cursor.
  3. The Secret Sauce: Hit Cmd + I (Composer Mode) in Cursor. Type this:“Analyze this project structure. Set up a basic landing page using Tailwind CSS with a Hero section that explains ‘AI Resume Roaster’. Use a dark theme.”

✨ Magic: Watch as Cursor creates the file, writes the code, and imports the components. You didn’t type a single <div>.

🎨 Minute 10-25: Design without Dragging

We need a beautiful UI, but we aren’t designers. Enter v0.

  1. Go to v0.dev.
  2. Prompt: “Create a modern dashboard for a Resume Roasting app. Left sidebar for history, main area for PDF upload, and a right panel for the AI critique. Use shadcn/ui style, orange and black color scheme.”
  3. Copy & Paste: v0 generates the React code instantly. Click “Copy Code.”
  4. Cursor Integration: Go back to Cursor. Create app/dashboard/page.tsx. Paste the code. (Pro Tip: If there are errors, highlight the code and hit Cmd + K -> “Fix these import errors.”)

🧠 Minute 25-45: Logic & “Vibe Coding”

Now for the functionality. We need to handle file uploads and call an AI to roast the resume.

The Old Way:

  • Search Google for “Multer file upload.”
  • Search “OpenAI API python example.”
  • Debug async/await errors.

The Vibe Coding Way: Open Cursor Composer (Cmd + I) and type a Multi-File Prompt:

“I need to add functionality to this dashboard:

  1. Create a Server Action in actions.ts to handle PDF uploads.
  2. Extract text from the PDF.
  3. Send the text to OpenAI GPT-4o with a prompt to ‘Roast this resume brutally’.
  4. Display the result in the right panel of the dashboard page. Handle all loading states.”

🔥 Watch the Fireworks: Cursor will open multiple files, install necessary packages (like pdf-parse), write the API call, and wire it up to your UI button.

Your Job: You just review the code. Does it look right? Click “Accept All.”

💾 Minute 45-55: The Instant Backend

We need to save these roasts. We are not setting up a local database.

  1. Go to Supabase.com -> “New Project”.
  2. Copy the DATABASE_URL and ANON_KEY.
  3. Paste them into your .env file.
  4. Back to Cursor (Cmd + I):“Connect to my Supabase instance using Drizzle ORM. Create a schema for ‘roasts’ containing the user ID, the original resume text, and the AI response. Update the Server Action to save the result to the DB after generation.”

Cursor writes the schema. Cursor runs the migration. Done.

🚀 Minute 60: Deployment

We don’t configure servers in 2025.

  1. Push to GitHub.
  2. Go to Vercel.com -> “Add New Project”.
  3. Import from GitHub.
  4. Add your Environment Variables (OpenAI Key, Supabase URL).
  5. Hit Deploy.

🔮 The Takeaway

If you are still memorizing syntax, you are playing the game on Hard Mode.

Vibe Coding isn’t about being lazy; it’s about leverage. In 60 minutes, you did what used to take a team of three (Frontend, Backend, Designer) a full week.

Stop typing. Start vibing. 🌊
