With the internet expanding rapidly, a growing number of applications that were previously desktop-based have transitioned to the web. Now, people can easily access applications anywhere and anytime using the internet. To develop these applications rapidly and efficiently, developers require tools such as code editors having effective development environment. The process of creating software applications or systems through the joint effort of multiple individuals or teams is referred as Collaborative application development. This emphasizes communication, coordination and cooperation among team members to build a high-quality application. The developers share tasks, exchange ideas, and contribute their skills and expertise to deliver a final product. The integrated development environment by using web socket technology allows users to work together on a project in a real time. Most of the existing collaborative application development uses code editor applications, distributing questionnaires, and conducting literature reviews. The true collaborative application development must offer a workspace for writing codes, executing codes, display results along with real-time collaboration, chat or community options and terminal building etc. This research work is focused on the development of such collaborative application. Thus, collaborative application development empowers developers work together to design, develop, test as well as deploy an application
