Web application

Cadrant web applications are fullstack React.js applications with complete Supabase integration. They are designed for any use case requiring data persistence, authentication or advanced features.

Unlike a static website, a web application stores and updates data: user accounts, records created from the interface, dashboards that change with every action. Interface, server logic and database are generated together, in a single project.

Key features

• Fullstack React.js application with integrated backend
• Supabase integration for PostgreSQL database
• Complete authentication system (email, OAuth, etc.)
• Edge Functions for custom server logic
• Integrated file storage
• Real-time API with subscriptions

How it works

1. Describe the application in the chat: main screens, who logs in, which data you handle.
2. Cadrant generates the React interface and the data model your project needs.
3. Review the result in the live preview, then iterate screen by screen — one prompt, one change.
4. Connect Supabase to store data, authenticate users and run server-side logic.
5. Publish to a Cadrant URL or to your own domain.

Ideal use cases

• SaaS applications
• Dashboards and internal tools
• Marketplaces and e-commerce
• Collaborative applications
• Platforms with user accounts
• Any project requiring a database

Backend and data

A web application relies on Supabase, connected to your own account. Each part has its own page:

• Connect Supabase — link the project to your Supabase account.
• Database — tables, relations and queries generated from your prompts.
• Authentication — signup, login and access rules.
• Edge Functions — server-side logic that never runs in the browser.
• File storage — files and images uploaded by your users.
• Environment variables — API keys and secrets, kept out of the frontend.

Going further

• Prompting best practices — write prompts that produce the right result the first time.
• Versioning — roll back to any earlier version and push the code to GitHub.
• External API integrations — connect external services: payments, email, AI.
• Publish your project — put the application online, on a Cadrant URL or your domain.

Subscription

Web applications are available with the Starter subscription and higher plans. This subscription includes hosting, complete Supabase integration and all advanced features.
