Grav vs Mezzanine CMS: What are the differences?

### Introduction
When comparing Grav and Mezzanine CMS, there are several key differences that differentiate the two content management systems.

1. **Architecture**: Grav is flat-file based, meaning it does not require a database to function, which can simplify deployment and maintenance. On the other hand, Mezzanine is database-driven and relies on Django as its framework, offering advanced features like user authentication and content versioning.

2. **Flexibility**: Grav allows for more flexibility in terms of design and content structure due to its modular and extendable nature. Mezzanine, while versatile, may have constraints on customization compared to Grav's lightweight approach.

3. **Learning Curve**: Grav is known for its user-friendly interface and simplicity, making it easier for beginners to grasp and use effectively. Mezzanine, being built on Django, may have a steeper learning curve for users unfamiliar with Python or web development.

4. **Performance**: Grav is optimized for speed and performance, making it a good choice for projects where performance is a priority. Mezzanine, while robust, may require more resources due to its database-driven nature.

5. **Community and Support**: Grav has a growing community and active development, providing users with ongoing support and updates. Mezzanine also has a dedicated community, but being more established, it may have a larger pool of resources and plugins available.

6. **Scalability**: Grav is lightweight and can handle small to medium-sized websites efficiently, but may face challenges in scaling to large projects. Mezzanine, with its robust framework, is better suited for larger, enterprise-level websites requiring complex functionalities and scalability.

In Summary, Grav and Mezzanine CMS have key differences in architecture, flexibility, learning curve, performance, community support, and scalability, which make each platform suitable for different types of projects and user preferences.
