OpenFGA Studio – An Open Source Authorization Modeling Interface

OpenFGA Studio

Understanding OpenFGA

OpenFGA (Fine-Grained Authorization) is a high-performance authorization engine built for developers and inspired by Google’s Zanzibar paper. It excels in handling complex authorization scenarios with features that make it stand out:

  • Relationship-Based Authorization: Model complex access patterns through relationships
  • High Performance: Process millions of authorization checks per second
  • Flexibility: Support for RBAC, ABAC, and ReBAC models
  • Time-Based Access: Define temporal access rules with built-in support
  • Proven Architecture: Based on Google’s battle-tested Zanzibar system

While OpenFGA Playground provides a hosted application for experimentation, it comes with limitations:

  • Not open source
  • Cannot be deployed in air-gapped environments
  • Limited customization options
  • Dependency on external services

Why This Project?

I built OpenFGA Studio to address these limitations and provide:

  • A fully open-source solution deployable anywhere
  • Enhanced user experience for authorization modeling
  • Complete control over your authorization data
  • Customizable interface for specific needs
  • Seamless integration with existing systems

OpenFGA Studio streamlines the process of creating, testing, and managing authorization models, making complex authorization logic more accessible and manageable. Built with modern web technologies including React, TypeScript, and Material-UI, it provides a robust and intuitive interface for working with OpenFGA.

Key Features

1. Store Management

The interface provides a straightforward way for managing OpenFGA stores. You can:

  • Create new authorization stores
  • Switch between existing stores
  • View and manage store configurations
  • Track model versions and changes

Store Creation Interface

2. Visual Authorization Model Editor

The model editor is a powerful interface for defining authorization rules with features including:

  • Syntax highlighting for better readability
  • Real-time validation against OpenFGA schema
  • Support for both DSL and JSON formats
  • Error highlighting and suggestions
  • Easy switching between model versions

3. Interactive Graph Visualization

Understand your authorization model at a glance with:

  • Visual representation of relationships between types
  • Interactive node exploration
  • Relationship flow visualization
  • Dynamic updates as you modify the model
  • Zoom and pan controls for large models

4. Advanced Tuple Management

The tuple management interface makes it easy to define and manage relationships:

Adding Basic Tuple

  • Assisted tuple creation with type suggestions
  • Support for direct (freeform) tuple input
  • Batch operations for efficient management
  • Reverse chronological listing of tuples
  • Quick delete operations

5. Conditional Relationship Support

Handle complex authorization scenarios with conditional relationships:

Adding Tuple with Conditions

  • Dynamic condition parameter inputs
  • Type-aware parameter validation
  • Timestamp and duration support
  • Visual feedback for condition state

6. Comprehensive Query Testing

Test your authorization rules with an intuitive interface:

Basic Access Validation

Features include:

  • Visual query builder
  • Direct query input support
  • Real-time query validation
  • Historical query tracking
  • Quick query replay

7. Conditional Access Testing

Test complex conditional access patterns:

Conditional Access Validation

  • Test time-based access rules
  • Validate contextual conditions
  • Dynamic parameter inputs
  • Clear success/failure indicators

8. Developer-Friendly Features

OpenFGA Studio is built with developers in mind:

  • Clean, modern UI with dark mode support
  • Keyboard shortcuts for common operations
  • Copy/paste support for all fields
  • Detailed error messages
  • Response timing information

Technical Implementation

OpenFGA Studio is built with modern web technologies:

  • Frontend: React with TypeScript for type safety
  • UI Framework: Material-UI for consistent, responsive design
  • State Management: React hooks and context for efficient state handling
  • Build Tool: Vite for fast development and optimized production builds
  • API Integration: Axios for reliable API communication
  • Graph Visualization: React Flow for interactive model visualization

Common Use Cases

  1. Authorization Modeling

    • Design role-based access control (RBAC) systems
    • Implement attribute-based access control (ABAC)
    • Model relationship-based authorization

  2. Testing and Validation

    • Verify access control rules
    • Test time-based permissions
    • Validate complex conditional access

  3. Development and Debugging

    • Debug authorization issues
    • Prototype authorization models
    • Document access control patterns

Conclusion

OpenFGA Studio simplifies the complex task of fine-grained authorization modeling and testing. Whether you’re designing a new authorization system or maintaining an existing one, this tool provides the features needed to work efficiently with OpenFGA.

The combination of visual tools, intuitive interfaces, and powerful testing capabilities makes it an essential tool for developers working with authorization systems. The tool continues to evolve with new features and improvements based on community feedback and real-world usage patterns.

Maven and Cloud Foundry Integration

Cloud Fountry provides as easy integration plugins to move the build packages to its servers through Maven. Here is the sample configuration.

Add Servers to settings.xml

<settings> 
	...
	<servers>
		... 
		<server>
			<id>cloud-foundry-credentials</id>
			<username>cf_user_id_you_created</username>
			<password>cf_password_you_created</password>
		</server>
	</servers> 
</settings>

You can encrypt you password in MAVEN settings. Check out here on how to do it.

Add Dependency and Plugin settings in pom.xml

</project>
	...	
	<build>
		...
		<plugins>
				<groupId>org.cloudfoundry</groupId>
				<artifactId>cf-maven-plugin</artifactId>
				<version>1.1.3</version>
				<configuration>
					<server>cloud-foundry-credentials</server>
					<target>https://url.to.cloud.foundry.com</target>
					<memory>512</memory>
					<appname>application-name</appname>
					<org>ORG_NAME</org>
					<space>SPACE_NAME</space>
					<instances>1</instances>
				</configuration>
				<executions>
					<execution>
						<phase>package</phase>
						<goals>
							<goal>push</goal>
						</goals>
					</execution>
				</executions>
		</plugins>
	</build>
</project>

Thats it !!. Build you project using Maven and check if you application gets deployed into your Cloud Foundry server.

Open Source Softwares – Top alternatives for proprietary softwares

Open source software is software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees. Open source code evolves through community cooperation. These communities are composed of individual programmers as well as very large companies. Click Here to learn more about Open Source Softwares.

The Open Source softwares get developed rapidly as the development involves developers from individual to lage companies. Thus the Open Source softwares are gaining phase and becoming a competitive products to that of the costly and proprietary softwares in the market. Here is a collection of softwares that stand as the great alternatives to the Proprietary gaints.
