Ember Source is the core library of the Ember.js framework, providing a robust set of tools and conventions for building ambitious web applications. It offers a strong focus on developer productivity and follows the convention over configuration principle, making it easier to get started with complex web projects. Ember Source includes features like two-way data binding, computed properties, and a powerful routing system.
Marko is a fast and lightweight JavaScript UI library for building web applications with a focus on server-side rendering. It offers a component-based architecture that allows developers to create reusable and encapsulated UI components. Marko provides efficient server-side rendering, resulting in faster page loads and improved SEO performance.
Ember.js is a well-established framework with a dedicated community, while Marko is a newer and less widely adopted library. Ember.js has been around for longer and has a larger user base compared to Marko.
Scalability
Ember.js is known for its convention over configuration approach, which makes it great for large-scale applications with a lot of structure. Marko, on the other hand, is more lightweight and flexible, making it suitable for smaller projects or microservices.
Performance
Ember.js has a more opinionated structure and includes many features out of the box, which can impact performance, especially in smaller applications. Marko, being more lightweight, tends to have better performance in smaller projects but might require more manual optimization in larger applications.
Developer Experience
Ember.js provides a lot of tools and conventions to streamline development, which can be beneficial for developers who prefer a more structured approach. Marko, on the other hand, offers more flexibility and allows developers to have more control over their code, which can be appealing to those who prefer a more hands-on approach.
Community Support
Ember.js has a strong and active community with a wealth of resources, plugins, and addons available. Marko, being newer, might have a smaller community and fewer resources available, which could impact the level of support and available solutions for common problems.
