Welcome to Supasheet

What is Supasheet?

Supasheet is a complete CMS platform built on Supabase. It's an opinionated, full-fledged open-source CMS with everything included. Go beyond basic admin panels with built-in authentication, dashboards, charts, reports, file management, and comprehensive data tools.

It provides a powerful, SQL-first approach where you primarily write SQL to define your application, and Supasheet handles the UI layer automatically.

Key Features

• Authentication: Complete user authentication system with Supabase Auth
• User Management: Comprehensive user administration and profile management
• Authorization (RBAC): Role-based access control with PostgreSQL Row Level Security
• Resource (CRUD): Auto-generated CRUD interfaces from your database schema
• Data Views: Multiple view types - Sheet, Kanban, Calendar, and Gallery
• Customizable UI: Flexible theming and component customization
• SQL Editor: Built-in SQL editor for direct database management
• Dashboard: Customizable dashboards for data visualization
• Analytics: Built-in analytics and metrics tracking
• Reports: Generate custom reports from SQL queries
• Charts: Create visualizations using SQL views
• File Storage: Complete file upload and management with Supabase Storage
• Audit Logs: Automatic change tracking using PostgreSQL triggers

How It Works

Supasheet is built on top of Supabase's powerful features:

• PostgREST: Automatic REST API from your PostgreSQL database
• Supabase Auth: Built-in authentication with JWT and social providers
• Supabase Storage: Complete file storage and CDN management
• Row Level Security (RLS): PostgreSQL policies for fine-grained authorization
• Realtime: Real-time subscriptions for live data updates

The frontend (Next.js 16 + React 19) dynamically renders a complete CMS interface based on your database schema. You define your data model and business logic in SQL, and Supasheet automatically generates:

• CRUD interfaces for all tables
• Multiple data view types (Sheet, Kanban, Calendar, Gallery)
• Dashboards and analytics
• Reports and charts
• File management UI
• User administration
