How to integrate Supabase with Webflow

Supabase turns static Webflow sites into dynamic applications by providing backend services like databases, authentication, and real-time features.

You can connect Webflow and Supabase through third-party apps for visual no-code data binding, custom Code Embeds for authentication forms and real-time displays, or Webflow and Supabase APIs for complete control over data synchronization and custom workflows.

Use third-party apps

Third-party apps connect Webflow and Supabase without requiring code, making database integration accessible to non-technical users. These visual tools handle authentication tokens automatically and provide drag-and-drop interfaces for mapping data between platforms.

One of these tools is Wized. It provides visual data binding between Supabase tables and Webflow elements.

To get started with Wized:

1. Install Wized from the Apps panel in Webflow
2. Configure data sources pointing to your Supabase project
3. Map database fields to Webflow elements through the visual interface

BuildShip creates API workflows connecting Webflow Forms to Supabase databases. Its node-based editor lets you:

• Route form submissions directly to Supabase tables with field mapping
• Sync CMS collections bidirectionally between platforms
• Trigger automated workflows when database changes occur

For bidirectional data synchronization, Whalesync provides a Supabase connector that syncs Webflow CMS collections with Supabase tables. Configure field mappings through Webflow’s visual interface, set conflict resolution rules, and enable real-time syncing between platforms.

Use custom Code Embeds

You can connect Supabase directly to Webflow using custom code and embedded JavaScript. This approach works well for authentication forms and real-time data displays where you need more control than third-party apps provide.

To set up custom code integration:

1. Add the Supabase client library to your site's custom code section
2. Initialize connections to your Supabase project
3. Use Code Embed elements to inject Supabase components anywhere on your page

Common implementations include:

• Authentication widgets using Supabase's new UI Library components or custom authentication forms
• Real-time dashboards displaying live data from Supabase tables
• File upload forms connecting to Supabase Storage Buckets

Configure these embeds by pasting initialization code that includes your Supabase project URL and public API key. The embedded components inherit your site's styling while adding dynamic functionality.

Build with Webflow and Supabase APIs

Direct Webflow API integration provides complete control over data synchronization, authentication flows, and real-time features. This approach suits teams needing custom business logic, complex data relationships, or integration with existing systems beyond what visual tools offer.

Supabase's auto-generated REST API creates endpoints for every database table, while Webflow's Data API allows programmatic CMS management. Combining these APIs through serverless functions or backend services allows automated content publishing, user-generated content moderation, and multi-tenant applications.

Implement user authentication systems

Build secure authentication flows that go beyond basic login forms. Create a comprehensive user management system that protects user data and personalizes content.

To set up authentication:

1. Set up Supabase Auth with your preferred providers (email/password, OAuth, magic links)
2. Configure Row Level Security policies to protect user data based on authentication status
3. Sync user profiles between Supabase and Webflow CMS using Edge Functions

The Supabase Auth API provides endpoints for user registration, session management, and password recovery. Implement these in Webflow through custom JavaScript that handles form submissions and manages authentication state. User sessions persist across page loads, enabling personalized content and protected routes.

Create real-time collaborative features

Enable live updates and multiplayer functionality using Supabase's Realtime engine. This allows multiple users to see changes instantly without refreshing their browsers.

To implement real-time features:

1. Subscribe to database changes using the Realtime API to monitor specific tables
2. Broadcast custom events between users for features like live cursors or presence indicators
3. Update Webflow elements dynamically when data changes occur

Connect to Realtime channels through JavaScript, then bind updates to specific Webflow elements. This enables collaborative features like shared shopping carts, live comment sections, or real-time analytics dashboards without page refreshes.

Automate content workflows

Synchronize content between platforms using webhooks and Edge Functions. This allows automated publishing workflows where content created in Supabase automatically appears in Webflow.

To set up automated workflows:

1. Configure Supabase webhooks to trigger on database events using the Database Webhooks feature
2. Process events in Edge Functions to transform data and handle business logic
3. Update Webflow CMS via the Collections API to reflect changes

This pattern enables automated publishing workflows where content created in Supabase automatically appears in Webflow, complete with SEO optimization and proper formatting. Set up error handling and retry logic to ensure reliable synchronization even during network issues.

What you can build

Integrating Supabase with Webflow enables sophisticated applications that combine visual design with powerful backend capabilities.

• A membership platform with secure authentication, subscription management, and gated content areas powered by Supabase Auth and Row Level Security
• Dynamic e-commerce stores that sync inventory between Supabase and Webflow, display real-time stock levels, and process orders through integrated payment systems
• Collaborative workspaces where multiple users edit content simultaneously, with changes instantly reflected across all connected sessions
