What You're Building

You will create a subscription-based SaaS web app that allows users to sign up, log in, and access a core feature behind a paywall. The app includes user authentication, a simple but valuable core functionality (such as a task manager, analytics dashboard, or content platform), and Stripe-powered subscription billing. The MVP will be fully functional for early customers, with a clean UI, secure user data, and automated payment handling.

Before You Start

Set up accounts on the recommended platforms: Lovable or Bolt.new for app building, Supabase for database and authentication, Stripe for payments, and Vercel or Railway for hosting. Decide on your core feature scope — keep it minimal and focused. Familiarize yourself with Vibe Coding basics and the chosen app builder’s interface. Prepare your branding assets (logo, color scheme) to speed up UI design.

Step-by-Step Approach

  1. Design your app UI and data model: Use Lovable or Bolt.new to sketch screens and define the database schema in Supabase. Keep user flows simple: signup/login, main feature, billing page.
  2. Implement authentication: Connect your app builder to Supabase Auth. Test signup, login, password reset flows thoroughly before moving on.
  3. Build the core feature: Develop the main functionality using Vibe Coding’s components and Supabase queries. Focus on MVP-level completeness, not perfection.
  4. Integrate Stripe billing: Set up Stripe products and pricing. Use your app builder’s Stripe integration to handle subscriptions, billing portals, and webhook events.
  5. Deploy your app: Connect your Git repo to Vercel or Railway and deploy. Test the live app end-to-end, including payments and auth.
  6. Collect feedback and iterate: Launch to a small group of users, gather feedback, fix bugs, and plan your next features.

Realistic Time Estimates

  • First prototype: 1–3 days to wireframe UI and set up basic auth with Supabase.
  • MVP with core feature and billing: 1–2 weeks depending on complexity and learning curve.
  • Production-ready app: 1–3 months including polishing UI, security hardening, and scaling infrastructure.

Common Mistakes and How to Avoid Them

  • Overbuilding features: Stick to one core feature for the MVP. Avoid feature creep that delays launch.
  • Ignoring security: Properly configure Supabase Row Level Security and Stripe webhook verification to protect user data and payments.
  • Skipping testing: Test auth flows and payment processes thoroughly to avoid user lockouts or billing errors.
  • Choosing complex billing models too early: Start with simple subscription tiers before adding coupons, trials, or metered billing.

When Vibe Coding Works Well Here

Vibe Coding shines when you want to rapidly prototype and iterate on a SaaS MVP without deep backend expertise. The integration between app builders, Supabase, and Stripe reduces boilerplate and lets you focus on your product. It’s ideal for indie hackers and non-technical founders who want to launch quickly and validate ideas.

When It Doesn't

If your SaaS requires highly custom backend logic, complex workflows, or advanced scaling from day one, Vibe Coding’s abstraction may feel limiting. Also, if you need offline-first capabilities or mobile apps, this stack is less suitable. In those cases, consider traditional full-stack frameworks or native development.
