Turn your existing backend into a live, reactive data source. Ship modern UIs in hours, not weeks.
You have a working backend. You want to add a modern, responsive frontend.
The old way: Spend weeks building REST APIs, setting up state management, handling real-time updates, debugging sync issues.
StateZero: Your backend data just works in your frontend. Focus on the UI your users will love.
Users expect apps that feel instant and stay in sync. But implementing this is a nightmare:
// Basic CRUD is just the beginning...
const [users, setUsers] = useState([]);
const [loading, setLoading] = useState(true);
const [error, setError] = useState(null);
// Fetch data
useEffect(() => {
fetch('/api/users/')
.then(handleErrors)
.then(r => r.json())
.then(data => {
setUsers(data);
setLoading(false);
})
.catch(err => setError(err));
}, []);
// Optimistic updates (so UI feels instant)
const createUser = async (userData) => {
const optimisticUser = { ...userData, id: Date.now() }; // Fake ID
setUsers(prev => [...prev, optimisticUser]); // Show immediately
try {
const response = await fetch('/api/users/', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(userData)
});
const realUser = await response.json();
// Replace optimistic user with real one
setUsers(prev => prev.map(u =>
u.id === optimisticUser.id ? realUser : u
));
} catch (err) {
// Remove optimistic user on failure
setUsers(prev => prev.filter(u => u.id !== optimisticUser.id));
setError(err);
}
};
// Real-time updates (so everyone stays in sync)
useEffect(() => {
const ws = new WebSocket('ws://localhost:8000/users/');
ws.onmessage = (event) => {
const { type, user } = JSON.parse(event.data);
if (type === 'user_created') {
setUsers(prev => {
// Don't duplicate if we created optimistically
if (prev.find(u => u.id === user.id)) return prev;
return [...prev, user];
});
} else if (type === 'user_updated') {
setUsers(prev => prev.map(u => u.id === user.id ? user : u));
} else if (type === 'user_deleted') {
setUsers(prev => prev.filter(u => u.id !== user.id));
}
};
return () => ws.close();
}, []);
// And you still need:
// - Conflict resolution for simultaneous edits
// - Retry logic for failed optimistic updates
// - Cache invalidation across components
// - Connection state handlingYou wrote 100+ lines of complex infrastructure code and haven't built a single feature yet.
The cruel irony: Users expect instant, collaborative experiences, but implementing them properly takes months and is incredibly error-prone.
// With StateZero, modern app experiences become this simple:
import { useQueryset } from '@statezero/core/vue';
import { User } from './models';
const users = useQueryset(() => User.objects.all()); // Live, reactive, always current
const newUser = User.objects.create(userData); // Instantly visible everywhere
// That's it. You get:
// âś… Optimistic updates - UI feels instant on every action
// âś… Real-time sync - Changes from other users appear automatically
// âś… Conflict resolution - Simultaneous edits handled gracefully
// âś… Error handling - Failed operations auto-revert with user feedback
// 2 lines instead of 100+. Build your UI.# Keep your existing Django models exactly as they are
class User(models.Model):
name = models.CharField(max_length=100)
email = models.EmailField()
is_active = models.BooleanField(default=True)
def clean(self):
# Your business logic stays put
if User.objects.filter(email=self.email).exists():
raise ValidationError("Email already exists")
# Keep your existing permissions
class UserPermission(AbstractPermission):
def filter_queryset(self, request, queryset):
if request.user.is_staff:
return queryset
return queryset.filter(created_by=request.user)// Use them directly in your frontend - same syntax, same security
const activeUsers = useQueryset(() => User.objects.filter({ is_active: true }));
const myUsers = useQueryset(() => User.objects.filter({ created_by: currentUser.id }));
// Your permissions automatically apply
// Your validation automatically works
// Changes sync automatically everywhereBuilding with AI tools? Bolt.dev, v0, and Cursor create beautiful frontends, but connecting them to your backend usually means:
StateZero eliminates all of that. Your AI-generated frontend just works with your existing backend.
// AI generates this React component
const Dashboard = () => {
const orders = useQueryset(() => Order.objects.filter({
status: 'pending',
created_at__gte: lastWeek
}));
return (
<div>
{orders.map(order => (
<OrderCard key={order.id} order={order} />
))}
</div>
);
};
// It immediately works with your Django backend
// No API endpoints needed
// No state management required
// Real-time updates includedGot a Django app that's been running for years? StateZero gives you a migration path to modern SPAs without the usual rewrite:
# Your existing Django backend (unchanged)
class Product(models.Model):
name = models.CharField(max_length=100)
price = models.DecimalField(max_digits=10, decimal_places=2)
in_stock = models.BooleanField(default=True)<!-- Your new Vue frontend -->
<template>
<div class="product-grid">
<div v-for="product in products" :key="product.id" class="product-card">
<h3>{{ product.name }}</h3>
<p>${{ product.price }}</p>
<button @click="toggleStock(product)">
{{ product.in_stock ? 'In Stock' : 'Out of Stock' }}
</button>
</div>
</div>
</template>
<script setup>
import { useQueryset } from '@statezero/core/vue';
import { Product } from './models';
// This is all the JavaScript you write
const products = useQueryset(() => Product.objects.filter({ in_stock: true }));
const toggleStock = (product) => {
product.in_stock = !product.in_stock;
product.save(); // Validates in Django, updates everywhere instantly
};
</script>When someone else updates a product, your UI updates automatically. When you create a product, everyone else sees it instantly. No WebSocket code. No manual synchronization. It just works.
The modern app standard: Users expect Google Docs-style collaboration everywhere. Changes from other users should appear instantly, your actions should feel immediate, and everything should stay in sync.
The traditional nightmare: Implementing this requires WebSockets, optimistic updates, conflict resolution, connection state management, message queuing, and countless edge cases.
With StateZero: You get enterprise-grade real-time collaboration automatically.
<!-- Multiple users editing the same data -->
<template>
<div v-for="task in tasks" :key="task.id">
<input
v-model="task.title"
@input="task.save()"
:class="{ 'being-edited': task.isBeingEditedByOthers }"
/>
<span v-if="task.lastEditedBy">
Last edited by {{ task.lastEditedBy.name }}
</span>
</div>
</template>
<script setup>
import { useQueryset } from '@statezero/core/vue';
import { Task } from './models';
// This component automatically:
// - Shows changes from other users instantly
// - Handles optimistic updates for snappy UX
// - Resolves conflicts when users edit simultaneously
const tasks = useQueryset(() => Task.objects.filter({ project: currentProject.id }));
</script>No WebSocket code. No optimistic update logic. No conflict resolution. Real-time collaboration just works.
StateZero doesn't blur boundaries or create coupling. It creates a clean declarative data layer that sits between your frontend and backend:
Deploy them independently. Scale them separately. Your architecture stays proper.
→ Transform your first app in 15 minutes
Stop spending weeks on plumbing. Start building the features your users actually want.
Your backend works. Your data is solid. Now make it feel magical in the frontend.
StateZero: Build features, not plumbing.
