Day 5 of 8 · Lovable Foundation
Using Lovable with Other Tools
⏱ 6 min
📊 Beginner
A beautiful website is just the beginning. To make it truly functional, you'll want to connect it to other tools — databases, authentication, version control, and more.
Today you'll learn how Lovable integrates with key tools that turn your static site into a powerful application.
Supabase — your backend in minutes
Supabase is Lovable's built-in backend solution. It's an open-source alternative to Firebase that gives you:
A database — Store user data, content, orders, or anything else your app needs. Create tables and relationships without writing SQL.
Authentication — Add user sign-up, login, password reset, and social logins (Google, GitHub, etc.) with a single chat message.
File storage — Let users upload images, documents, or any files. Supabase handles the storage and delivery.
Real-time updates — Build features where data updates live — chat apps, dashboards, collaborative tools.
I want users to be able to create accounts and save their favorite recipes. Add authentication and a database for this.
I'll set up Supabase for you! Here's what I'm configuring:
🔐 **Authentication**
- Email/password sign up and login
- Protected routes (only logged-in users see saved recipes)
- Login and signup pages with form validation
🗄️ **Database**
- Users table (auto-created by auth)
- Recipes table (title, ingredients, instructions, image_url)
- Saved_recipes table (links users to their favorites)
- Row-level security so users only see their own saves
Connect your Supabase project in settings and I'll wire everything up!

Knowledge Check
What does Supabase provide for your Lovable project?
A
A database and user authentication, but file storage requires a separate service like AWS S3
B
A database and file storage, but you need a third-party auth provider like Auth0 for login
C
A complete backend including database and auth, but real-time updates require adding a WebSocket service
D
A database, authentication, file storage, and real-time features — a complete backend in one service
Supabase is a complete backend solution. It provides a PostgreSQL database, authentication, file storage, and real-time subscriptions — all of which Lovable can set up through chat.
GitHub — version control for your project
Lovable connects directly to GitHub, giving you:
Version history — Every change Lovable makes is tracked. You can see what changed and when.
Collaboration — Share your repository with others. Developers can make manual code changes alongside Lovable's AI edits.
Backup — Your code lives safely in GitHub, not just in Lovable. You always have access to your full codebase.
Deployment flexibility — With your code in GitHub, you can deploy to any hosting platform — Vercel, Netlify, or your own server.
To connect GitHub, go to your project settings in Lovable and link your GitHub account. Lovable will create a repository and push your code automatically.
Knowledge Check
Why should you connect your Lovable project to GitHub?
A
It allows Lovable to automatically run tests and catch bugs before deploying changes
B
It gives you version history, backup, collaboration, and deployment flexibility
C
It is required for publishing your site to a custom domain
D
It enables Lovable to generate higher-quality code by referencing your existing repositories
GitHub integration gives you version control, safe backups of your code, the ability to collaborate with developers, and the freedom to deploy your project anywhere. It's optional but highly recommended.
Custom domains
By default, Lovable gives your published site a `.lovable.app` subdomain. But for a professional presence, you'll want your own domain.
Lovable supports custom domains — connect a domain you own (from Namecheap, GoDaddy, Google Domains, or any registrar) and your Lovable site will be accessible at that address.
The setup is straightforward:
1. Buy a domain from any registrar
2. Go to your project's publish settings in Lovable
3. Add your custom domain
4. Update your DNS records as instructed
5. Your site is live at your custom URL
Knowledge Check
What domain does a Lovable site use by default?
A
A temporary preview URL that expires after 30 days unless you connect a custom domain
B
A .netlify.app subdomain, since Lovable deploys through Netlify by default
C
A .lovable.dev subdomain that matches your Lovable account name
D
A .lovable.app subdomain that is assigned automatically when you publish
Lovable provides a free .lovable.app subdomain for every published project. You can upgrade to a custom domain anytime by connecting one through your project's publish settings.
Other integrations and tools
Beyond Supabase and GitHub, here are other tools that work well with Lovable:
Stripe — Add payment processing to your site. Lovable can create checkout flows, subscription management, and pricing pages that connect to Stripe.
APIs and webhooks — Need to pull data from an external service or send form submissions to Zapier? Lovable can add API integrations through chat.
Analytics — Add Google Analytics, Plausible, or other tracking tools by asking Lovable to include the script tags.
Email services — Connect to Resend, SendGrid, or other email providers for contact form delivery, transactional emails, or newsletters.
I want to add Stripe payments so users can buy a $29/month subscription. Can you set that up?
I can build the frontend for Stripe integration:
💳 **What I'll create:**
- Pricing page with your $29/month plan highlighted
- Checkout button that redirects to Stripe Checkout
- Success and cancel pages after payment
- Subscription status display for logged-in users
You'll need to:
1. Create a Stripe account at stripe.com
2. Add your Stripe API keys in the Supabase edge function
3. Set up a webhook for subscription events

Final Check
Which combination of tools would you need to build a web app with user accounts, data storage, and payment processing?
A
Lovable + GitHub, since GitHub provides built-in authentication and database features
B
Lovable + Stripe only, because Stripe handles both user accounts and payment data storage
C
Lovable + Supabase for everything, since Supabase includes native payment processing
D
Lovable + Supabase (for auth and database) + Stripe (for payments)
For a full-featured web app, you'd use Lovable to build the frontend, Supabase for authentication and database, and Stripe for payment processing. Together, they give you everything you need without writing code.
