Feature modeling is a basic technique used in software product line development.Feature diagrams are an important product that describes the relationships between requirements and distinguishes between common and variable characteristics, and there are many tools available for drawing feature diagrams. After studying the available tools, we found that there are a lot of tools available to the user to download on the devices, which often become complex and difficult to use. Also, software requirements are increasing over time, and there are very few online tools and most of them do not provide all user requirements. In this project, we present an online tool that contains some solutions to these problems that developers face while using the tools to provide a more effective and easy-to-use tool.
