"Simplifies Complex Interfaces Without JavaScript"

5/5

What do you like best about ZK Framework?

I use ZK Framework for its server-side approach and its extensive collections of UI components that allow me to build complex enterprise applications using only Java. What really impresses me is its ability to create rich interfaces without relying on JavaScript, which drastically reduces the learning curve and speeds up development. ZK helps me eliminate front-end and back-end inconsistencies by handling everything server-side in Java, reducing maintenance complexity. I enjoy its rich UI components and the ability to create dynamic interfaces without JavaScript. I also appreciate the ease of scaling with Hibernate and the straightforward and smooth initial setup.

"Rapid Enterprise Web Development with ZK’s Powerful Java-Centric Approach"

5/5

What do you like best about ZK Framework?

ZK Framework stands out for its server-centric architecture and rich set of UI components that allow developers to build enterprise-grade web applications quickly and efficiently. The ability to create complex, responsive UIs using pure Java without needing deep knowledge of JavaScript or front-end frameworks is a major advantage. also appreciate ZK’s robust documentation, active community, and the fact that it integrates seamlessly with popular Java technologies like Spring and Hibernate. Overall, ZK enables rapid development while maintaining enterprise-level scalability and performance. Review collected by and hosted on G2.com.

What do you dislike about ZK Framework?

Honestly, there isn’t much to dislike about ZK Framework. It’s well-designed, stable, and meets most enterprise development needs efficiently. My overall experience has been very positive, the framework provides a great balance between productivity, flexibility, and performance. Review collected by and hosted on G2.com.

What problems is ZK Framework solving and how is that benefiting you?

ZK Framework has helped me build a highly dynamic and configurable system, where virtually nothing is hardcoded, all UI elements, configurations, and behaviours are driven directly from the database. This flexibility allows rapid customization without redeployment and significantly reduces development and maintenance effort.

It also solves the challenge of seamlessly connecting the front-end and back-end by allowing me to handle complex UI logic entirely in Java. This keeps the code clean, consistent, and easy to maintain.

Additionally, ZK simplifies real-time data updates through its built-in Ajax support, provides a rich set of ready-to-use components, and integrates smoothly with Spring and Hibernate, making it ideal for enterprise-grade applications. Overall, ZK has enabled me to deliver scalable, interactive applications faster and with fewer resources. Review collected by and hosted on G2.com.

"An essential API for enriched applications"

5/5

What do you like best about ZK Framework?

ZK is a framework that, as you use it, you become familiar with a way of doing things that allows you to approach any approach, from creating simple rich forms to complex forms where the screen structure is vital to the end user's performance. The use of complex components facilitates the work, such as table, graph, and portal components, which are the starting point for creating a new application.

For programmers, differentiating programming into different layers allows the team to focus on their task and then put the pieces together to complete the assigned work.

The fact that it is programmed in Java and has integration with JavaScript allows you to solve everything from a single code, whether partitioned or non-partitioned.

Using the customer support team has even allowed us to find solutions to problems that have arisen, making it easier for us to achieve our goal quickly and efficiently. Review collected by and hosted on G2.com.

What do you dislike about ZK Framework?

The only thing I miss is not having the ability to build a responsive phone app natively for iOS and Android. Review collected by and hosted on G2.com.

"A safe and efficient front-end development framework, with well-encapsulated components that are slightly complex."

4.5/5

What do you like best about ZK Framework?

I really like the ZK Framework because it allows for the creation of complex interfaces using JAVA+ZUL, and it has many components that can shorten the time from requirements to usable screens. The components are well encapsulated, which can reduce security risks. In terms of handling forms with a large number of fields, conditional queries, and batch editing, it can effectively save time. For systems developed in JAVA, UI development can be more closely aligned with backend processes. I find it relatively simple and easy to get started with in terms of setup. Review collected by and hosted on G2.com.

What do you dislike about ZK Framework?

Because it is a product, there are more restrictions on component modifications, and it is not easy. Most of the time, assistance from the original manufacturer is required, making it difficult to customize independently. Review collected by and hosted on G2.com.

What problems is ZK Framework solving and how is that benefiting you?

I easily develop complex interfaces using Java + ZUL. The ZK Framework provides rich components, speeding up the conversion of requirements into usable interfaces. Encapsulating components effectively reduces security risks, saves time on form and batch editing, and makes UI development more aligned with backend processes.
