Building a SaaS in a Weekend with Cursor and Vibe Coding

The "weekend project" used to be a myth. You'd spend Saturday setting up Webpack and Sunday fixing database migrations. Monday would arrive, and you'd have a "Hello World" app.

With Vibe Coding, the weekend launch is real. Here is the roadmap to building a SaaS in 48 hours using Cursor.

Friday Night: The Stack & The "Vibe"

Don't overthink. Choose a stack that is AI-friendly (popular, well-documented).

• Stack: Next.js, Tailwind, Supabase/Firebase, Stripe.
• The Setup: Use v0.dev or a starter kit to get the UI skeleton.
• Cursor Prompt: "Initialize a Next.js app with Shadcn UI and Supabase auth pre-configured."

Saturday Morning: Core Logic with Composer

This is where you sprint. Open Cursor's Composer (Cmd+I).

1. Database: "Create a Supabase schema for a 'Task Manager' with users, projects, and tasks." -> copy SQL to Supabase.
2. Backend: "Generate Server Actions for creating, reading, and updating tasks. Ensure Row Level Security."
3. Frontend: "Create a dashboard page that lists tasks. Use a Kanban board layout."

Time elapsed: 4 hours. (This used to take 2 weeks).

Saturday Afternoon: Polish & "Vibe Check"

Now you have a working ugly app. Make it vibe.

• Prompt: "Make this dashboard look modern and 'clean'. Use a soft blue color palette and rounded corners."
• Refactor: "The drag-and-drop feels laggy. Optimize the useEffect hook."

Sunday: Payments & Deploy

The final mile.

1. Stripe: "Add a pricing page with a 'Pro' monthly plan. Create a Stripe checkout session api route."
2. Landing Page: "Create a high-converting landing page explaining the value prop of 'AI Task Management'."
3. Deploy: Push to Vercel/Netlify. "Fix any build errors related to unused variables."

The Secret Sauce

• Don't write code: Read code. Verify code. Direct code.
• Iterate: Don't ask for perfection in step 1. Ask for "working," then "pretty," then "optimized."
• Use the Directory: Need an auth tool? A database helper? Check our Directory for compatible tools.

Conclusion

The bottleneck is no longer "can I code this?" It's "do I have a good idea?" If you have the idea, Vibe Coding gives you the hands to build it.

What will you build this weekend?
