Casbin vs Devise: What are the differences?

# Introduction
Here are the key differences between Casbin and Devise:

1. **Authorization Model**: Casbin uses a flexible access control model that can be used for various purposes, while Devise is specifically designed for authentication and user management.

2. **Policy Management**: Casbin allows users to define policies in a central location using a policy file or API, providing more control and convenience. In contrast, Devise relies on predefined mechanisms for user authentication and session management.

3. **Multi-Language Support**: Casbin supports multiple programming languages, making it versatile for a variety of applications, whereas Devise is primarily used with Ruby on Rails applications.

4. **Fine-Grained Control**: Casbin offers fine-grained access control capabilities down to the level of individual API endpoints or data fields, giving users more control over their authorization rules. Devise, on the other hand, focuses more on higher-level user authentication and session management.

5. **Community Support**: Casbin has a growing community with active development and support, providing users with ongoing updates and new features. Devise also has an active community but is more focused on Ruby on Rails development.

6. **Integration Capabilities**: Casbin can be easily integrated with various frameworks and platforms, allowing for seamless integration into different applications. Devise, being more Rails-specific, may require more customization for integration with other frameworks or systems.

# Summary
In Summary, Casbin offers a robust and flexible access control model with fine-grained control and multi-language support, while Devise is tailored more towards authentication and user management within Ruby on Rails applications.
