Step 1: Define Your App in Plain Language

The biggest mistake builders make is jumping straight into a tool without a clear product spec. Before you open Lovable or Cursor, write a one-page brief that answers these questions:

• What does this app do in one sentence?
• Who is the primary user?
• What are the 3–5 core features for version one?
• What data needs to be stored, and by whom?
• Does it require user authentication?

Example brief: "A client portal for freelance designers where clients can log in, view project status, upload files, and leave comments. Designers can update status and reply to comments. No payments needed in v1."

This brief becomes your prompt source for both Lovable and Cursor. The more specific it is, the less back-and-forth you'll need later.

Tip

Use ChatGPT or Claude to help you refine your brief before you start building. Ask it to identify edge cases or missing user flows. This five-minute step can save hours of rework.

Step 2: Generate Your App UI with Lovable

Lovable is a generative UI tool that turns natural language prompts into functional React components with real routing, state management, and responsive layouts. In 2026, it's become one of the fastest ways to go from idea to working front-end in under an hour.

1. Log into Lovable and click "New Project."
2. In the prompt field, paste a structured description of your app. Be specific: name the pages you need, the components on each page, and any interaction logic.
3. Lovable will generate a full multi-page React app. Review the output — it usually gets 70–80% right on the first pass.
4. Use the built-in chat to iterate: "Add a sidebar navigation with links to Dashboard, Projects, and Settings" or "Change the project card to show a status badge instead of a date."
5. Once the UI looks right, click "Open in GitHub" to push the generated code to a repository you own.

What Lovable Generates

• React components using Tailwind CSS
• Page routing via React Router
• Basic form handling and state logic
• A clean, organized folder structure

Common Mistake

Don't try to get everything perfect inside Lovable. It's optimized for speed and structure — not fine-grained logic. Get the UI scaffolding right, then move to Cursor for the rest.

Warning

Lovable's free tier limits the number of prompts per day. If you're doing serious project work, upgrade to Pro or batch your prompts strategically. Revex typically allocates a dedicated Lovable Pro seat per active client project.

Step 3: Connect Your Backend with Supabase

Lovable has native Supabase integration — one of the reasons Revex uses this stack for client MVPs. Supabase gives you a PostgreSQL database, authentication, real-time subscriptions, and file storage without writing backend code from scratch.

1. Inside Lovable, click "Connect Supabase" in the project settings panel.
2. Log into your Supabase dashboard and create a new project. Name it after your app.
3. Paste your Supabase URL and anon key into Lovable when prompted.
4. Use the Lovable chat to scaffold your database: "Create a Supabase table called 'projects' with columns: id, name, status, created_by, created_at."
5. Lovable will generate the SQL migration and wire it to your front-end components automatically.
6. Enable Row Level Security (RLS) in Supabase — this is non-negotiable for any app with user data.

Authentication Setup

For user login, ask Lovable to implement Supabase Auth: "Add email/password authentication with a login page, registration page, and protected routes." Lovable handles the auth flow; Supabase handles the session management. It takes about 10 minutes.

Tip

Create at least two test user accounts in Supabase early on — one as an "admin" and one as a "regular user." Test your RLS policies with both accounts before you ship anything.

Step 4: Use Cursor for Logic, Fixes, and Custom Features

This is where the workflow shifts. Once you've pushed your Lovable-generated code to GitHub, clone the repository and open it in Cursor — an AI-native code editor built on VS Code.

Cursor is the power layer of this stack. It reads your entire codebase and lets you make precise, context-aware changes using natural language. Think of it as a senior developer who already knows every file in your project.

How to Use Cursor Effectively

1. Open Cursor and clone your GitHub repo: git clone [your-repo-url]
2. Open the project folder. Cursor will index the codebase automatically.
3. Use Ctrl+K (inline edit) for small, targeted changes to a specific file or function.
4. Use Ctrl+L (chat) to ask questions about your codebase or request multi-file changes: "Where is the user authentication logic handled?" or "Refactor the project card component to accept a status prop and render a color-coded badge."
5. Use Cursor Composer (Ctrl+Shift+I) for large, multi-file feature additions: "Add a comments system to the project detail page. Comments should be stored in a Supabase 'comments' table with user_id, project_id, body, and created_at. Display them below the project details in chronological order."

What to Use Cursor For

• Business logic that Lovable can't easily handle
• API integrations (Stripe, Resend, Twilio, etc.)
• Complex form validation
• Performance optimizations
• Bug fixes and error handling
• Writing and running tests

Common Mistake

Don't give Cursor vague prompts. Instead of "fix the login," say "the login form is submitting but not redirecting to /dashboard after a successful Supabase auth response — fix the post-login redirect logic in AuthForm.tsx." Specificity is everything.

Warning

Cursor's AI suggestions are powerful but not infallible. Always review the diff before accepting changes — especially on authentication or database query logic. Revex's internal process requires a human review of all Cursor-generated changes touching auth or data access layers.

Step 5: Sync Changes Back and Keep the Loop Clean

One of the most common workflow failures in vibe coding is losing track of which version of your code is the source of truth. Here's how to keep the Lovable ↔ Cursor loop clean:

1. Make your Lovable changes first (UI structure, new pages, layout updates).
2. Push from Lovable to GitHub.
3. Pull the latest changes into Cursor: git pull origin main
4. Make your logic and feature changes in Cursor.
5. Commit and push from Cursor: git add . && git commit -m "Add comments feature" && git push
6. If you return to Lovable, sync it with the latest GitHub state before making more UI changes.

The rule: Lovable owns the UI shell. Cursor owns the logic layer. When both try to own the same file without syncing, you get merge conflicts and broken builds.

Tip

Use clear commit messages. When you're working fast, it's tempting to write "fix stuff" — but two weeks later you'll have no idea what changed. Cursor can actually help you write good commit messages: "Write a descriptive git commit message for these changes."

Step 6: Deploy to Vercel

Deployment with this stack is fast. Vercel has first-class support for React apps and integrates directly with GitHub for continuous deployment.

1. Go to vercel.com and log in with your GitHub account.
2. Click "Add New Project" and import your repository.
3. Vercel will auto-detect it as a React/Vite project and configure the build settings.
4. Add your environment variables in the Vercel dashboard: your Supabase URL, anon key, and any API keys used in your app.
5. Click "Deploy." Your app will be live at a .vercel.app URL within 2–3 minutes.
6. Connect a custom domain under Project Settings → Domains if needed.

From this point on, every push to your main GitHub branch will trigger an automatic redeploy. Your app stays current without any manual deployment steps.

Estimated Total Timeline

• Simple CRUD app (3–5 pages): 4–8 hours
• Client portal or internal tool (8–12 pages): 2–4 days
• Full MVP with auth, payments, and notifications: 1–2 weeks

Step 7: Test, Iterate, and Avoid the Most Common Mistakes

Before you share your app with real users, run through this checklist:

• Authentication: Can users register, log in, log out, and reset their password?
• Data access: Can a user see or modify another user's data? (If yes, your RLS policies need work.)
• Mobile responsiveness: Open your app on a real phone — Tailwind is responsive by default but verify your layouts.
• Error states: What happens when a form submission fails? Is there a visible error message?
• Loading states: Does the UI show a spinner or skeleton while data fetches?
• Empty states: What does the dashboard look like for a brand-new user with no data?

Use Cursor to address any gaps: describe the issue and the file it's in, and ask for a fix. Most of these are 5–15 minute corrections.

When to Bring in a Professional

This stack handles most MVPs well. But there are scenarios where Revex recommends bringing in expert support:

• You need complex payment logic (subscriptions, metered billing, refunds)
• Your app handles sensitive data requiring HIPAA or SOC 2 compliance
• You're scaling beyond 1,000 concurrent users
• You need native mobile apps, not just mobile-responsive web
• Your team needs ongoing maintenance without technical co-founders
