Within a short period, the Internet and World Wide Web have become widespread, surpassing all other technological developments in our history. They have also grown rapidly in their scope and extent of use, significantly affecting all aspects of our lives. The scope and complexity of current Web applications is vary, from small-scale to large-scale enterprise applications distributed across the intranets and extranets. As Web applications have evolved, the demands placed on complexity of designing, developing and maintaining have also increased significantly. However, very little has been said about the maintainability factor. Poorly developed Web applications that continue to expand have a high probability of failure. The costs of bad design have many serious consequences. Therefore, new quality model and Web applications model must be developed for web applications. The model is needed to assess the elements of Web applications. Thus, the study is conducted on the maintainability of Web applications in accordance with ISO 9126. In order to evaluate the maintainability in Web applications, static analysis was applied. A static analysis is used to evaluate internal metrics for Web applications code. To prove and validate the metrics, experiment has been done. The experiment was done to identify the appropriate metrics for Web applications. The result of the study clearly point up the maintainability metrics consisting of separation, reuse and split-into. A Maintainability Evaluation Tool (MaEt) was developed to measure internal metrics in order to assist web developer or web designer in evaluating and creating maintainable Web applications.
