This guide will help you integrate third-party authentication, databases, and membership platforms to make your workspace fully functional with real user accounts and data persistence.
Landingsite.ai is a frontend-only platform. It cannot:

For most use cases, we recommend Supabase because:
The open-source Firebase alternative with PostgreSQL database, authentication, and real-time subscriptions
1.1 Go to supabase.com and sign up for free
1.2 Create a new project:
zonepedia-workspace
1.3 Wait 2-3 minutes for project setup
Note: Save your project URL and API keys (anon key) - you'll need them later
Go to SQL Editor in Supabase and run this SQL:
-- Create users table (extends Supabase auth.users)
CREATE TABLE public.user_profiles (
id UUID REFERENCES auth.users PRIMARY KEY,
full_name TEXT,
plan TEXT NOT NULL DEFAULT 'free',
ideas_generated INTEGER DEFAULT 0,
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);
-- Create saved ideas table
CREATE TABLE public.saved_ideas (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
user_id UUID REFERENCES auth.users NOT NULL,
title TEXT NOT NULL,
description TEXT,
data JSONB,
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);
-- Enable Row Level Security
ALTER TABLE public.user_profiles ENABLE ROW LEVEL SECURITY;
ALTER TABLE public.saved_ideas ENABLE ROW LEVEL SECURITY;
-- Create policies (users can only access their own data)
CREATE POLICY "Users can view own profile"
ON public.user_profiles FOR SELECT
USING (auth.uid() = id);
CREATE POLICY "Users can update own profile"
ON public.user_profiles FOR UPDATE
USING (auth.uid() = id);
CREATE POLICY "Users can view own ideas"
ON public.saved_ideas FOR SELECT
USING (auth.uid() = user_id);
CREATE POLICY "Users can insert own ideas"
ON public.saved_ideas FOR INSERT
WITH CHECK (auth.uid() = user_id);
CREATE POLICY "Users can delete own ideas"
ON public.saved_ideas FOR DELETE
USING (auth.uid() = user_id);
This creates secure tables where users can only access their own data
Go to Authentication → Settings:
Enable Email Authentication
Allow users to sign up with email/password
Add Site URL
Set to:
https://zonepedialaunchpad.com
Add Redirect URLs
https://zonepedialaunchpad.com/workspace
Disable Email Confirmation (Optional)
For testing, you can disable email confirmation
Go to Project Settings → API
Project URL:
https://xxxxx.supabase.co
Anon/Public Key:
eyJhbGc...
Important: The anon key is safe to use in frontend code. Never expose the service_role key!
You'll need to modify the workspace page to use Supabase instead of localStorage. Here's the code structure:
Add Supabase CDN to workspace page head section:
<script src="https://cdn.jsdelivr.net/npm/@supabase/supabase-js@2"></script>
Initialize Supabase in your JavaScript:
// Replace with your actual values
const SUPABASE_URL = 'https://xxxxx.supabase.co'
const SUPABASE_ANON_KEY = 'eyJhbGc...'
// Initialize Supabase client
const supabase = window.supabase.createClient(SUPABASE_URL, SUPABASE_ANON_KEY)
// Sign up new user
async function signUp(email, password, fullName, plan) {
const { data, error } = await supabase.auth.signUp({
email,
password,
options: {
data: {
full_name: fullName,
plan: plan
}
}
})
if (error) {
console.error('Error signing up:', error)
return null
}
// Create user profile
await supabase.from('user_profiles').insert({
id: data.user.id,
full_name: fullName,
plan: plan
})
return data
}
// Sign in existing user
async function signIn(email, password) {
const { data, error } = await supabase.auth.signInWithPassword({
email,
password
})
if (error) {
console.error('Error signing in:', error)
return null
}
return data
}
// Get current user
async function getCurrentUser() {
const { data: { user } } = await supabase.auth.getUser()
return user
}
// Sign out
async function signOut() {
const { error } = await supabase.auth.signOut()
if (error) console.error('Error signing out:', error)
}
// Save idea
async function saveIdea(userId, title, description, data) {
const { error } = await supabase.from('saved_ideas').insert({
user_id: userId,
title,
description,
data
})
if (error) {
console.error('Error saving idea:', error)
}
}
// Get saved ideas
async function getSavedIdeas(userId) {
const { data, error } = await supabase
.from('saved_ideas')
.select('*')
.eq('user_id', userId)
.order('created_at', { ascending: false })
if (error) {
console.error('Error fetching ideas:', error)
return []
}
return data
}
Tip: Replace the localStorage code in your workspace JavaScript with these Supabase functions
Since Landingsite.ai can't handle Stripe webhooks, you have two options:
Easiest - No code required
Requires external service (Vercel/Netlify)
Recommended for Starting: Use Option A (manual) to validate your business, then move to Option B when you have consistent sales
PostgreSQL Database
Powerful, scalable, relational database
Built-in Authentication
Email, social login, magic links
Row Level Security
Users can only access their data
Real-time Subscriptions
Live data updates automatically
File Storage
Upload PDFs, images, documents
Edge Functions
Run serverless code when needed
Google's comprehensive app development platform with authentication, Firestore database, and cloud functions
Create Firebase Project
Add Web App
Register your app and copy config
Enable Authentication
Turn on Email/Password in Auth section
Create Firestore Database
Start in test mode, then add security rules
Add Firebase SDK
Include in your workspace page
// Add to workspace head section
<script src="https://www.gstatic.com/firebasejs/10.7.0/firebase-app-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/10.7.0/firebase-auth-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/10.7.0/firebase-firestore-compat.js"></script>
<script>
// Initialize Firebase
const firebaseConfig = {
apiKey: "YOUR_API_KEY",
authDomain: "your-app.firebaseapp.com",
projectId: "your-project",
storageBucket: "your-app.appspot.com",
messagingSenderId: "123456",
appId: "YOUR_APP_ID"
};
firebase.initializeApp(firebaseConfig);
const auth = firebase.auth();
const db = firebase.firestore();
// Sign up
auth.createUserWithEmailAndPassword(email, password)
.then((userCredential) => {
// Create user profile
db.collection('users').doc(userCredential.user.uid).set({
fullName: name,
plan: plan,
createdAt: firebase.firestore.FieldValue.serverTimestamp()
});
});
// Sign in
auth.signInWithEmailAndPassword(email, password);
// Get current user
auth.onAuthStateChanged((user) => {
if (user) {
// User is signed in
console.log(user);
}
});
</script>

Important Note
Clerk is primarily for authentication. You'll still need a database (Supabase, Firebase, or Airtable) to store user data, saved ideas, and other information.
Clerk DocumentationUse Airtable as a simple database - great for storing user data and business ideas
Simple Data Storage
Store user profiles, saved ideas, form submissions
Easy Manual Management
View and edit data in spreadsheet interface
Quick Prototyping
Test your idea before building complex backend
No Built-in Authentication
You'll need another service for login/signup
API Rate Limits
5 requests per second on free tier
Not Real Database
Better for prototypes than production apps
Best Use Case
Combine Airtable with Clerk or Memberstack: Use Clerk/Memberstack for authentication, then use Airtable to store user-generated content and data. Simple and effective!
Airtable API DocsFor full control and unlimited possibilities, build a separate app on a subdomain
zonepedialaunchpad.com
app.zonepedialaunchpad.com
This is the professional approach: Keep your beautiful marketing site on Landingsite.ai, and build the actual app functionality separately with full backend capabilities.

Configure DNS to point
app.zonepedialaunchpad.com
to your hosting provider (Vercel, Netlify, etc.)
In your DNS settings, add a CNAME record:
app → cname.vercel-dns.com
Create a new Next.js app with TypeScript and Tailwind CSS
npx create-next-app@latest zonepedia-app --typescript --tailwind --app
Install and configure Supabase or your chosen auth provider
npm install @supabase/supabase-js @supabase/auth-helpers-nextjs
Create an API route to handle Stripe payment confirmations
// app/api/webhooks/stripe/route.ts
export async function POST(req: Request) {
const sig = req.headers.get('stripe-signature')
// Verify and process webhook
// Create user account
// Send welcome email
}
Deploy to Vercel, set up environment variables, and test the entire flow
vercel --prod
Change Stripe success URLs to point to your new app subdomain
success_url=https://app.zonepedialaunchpad.com/welcome?session_id={CHECKOUT_SESSION_ID}
Costs scale with usage. Most startups operate on free tiers initially.

Project setup, auth flow, basic pages
Week 2: Core Features
Dashboard, idea generation, data management
Week 3: Payment Integration
Stripe webhooks, plan management
Week 4: Polish & Deploy
