How to Get a Full Version of StarUML for Free

StarUML is a popular software modeling tool that supports UML (Unified Modeling Language) and MDA (Model Driven Architecture). It has many features such as diagram creation, code generation, reverse engineering, model validation, and more. However, StarUML is not free and requires a license key to activate the full version.

If you want to use StarUML without paying for a license key, you can try some methods that are available online. One of them is to modify a file called LicenseManagerDomain.js in the StarUML installation folder. This file is responsible for validating the license key and returning the license information. By changing some lines of code in this file, you can trick StarUML into thinking that you have a valid license key.

Here are the steps to follow:

  1. Download and install StarUML from https://staruml.io/download.
  2. Open the LicenseManagerDomain.js file with a text editor. You can find it in one of these locations depending on your operating system:
    • Windows: C:\Program Files (x86)\StarUML\www\license\node\
    • Mac OS: /Applications/StarUML.app/Contents/www/license/node/
    • Linux: /opt/staruml/www/license/node/
  3. Replace the validate function with this code:
    function validate(PK, name, product, licenseKey) {
        name: "sontd",
        product: "StarUML",
        licenseType: "vip",
        quantity: "unlimited",
        licenseKey: "no, thanks!"

    This code will return a fake license information that will make StarUML think that you have a VIP license with unlimited quantity.

  4. Save the file and close the text editor.
  5. Open StarUML and go to Help > Enter License.
  6. Enter any name and license key that match the ones you have written in the LicenseManagerDomain.js file. In this example, they are:
    Name: sontd
    License Key: no, thanks!
  7. Click OK and enjoy the full version of StarUML.

Note: This method may not work for future versions of StarUML or if the developers change the license validation mechanism. Use it at your own risk and respect the intellectual property rights of the software creators.

If you want to learn more about StarUML and how to use it for software modeling, you can visit the official website at https://staruml.io. There you can find the documentation, tutorials, examples, and support forums. You can also check out the blog for the latest news and updates on StarUML.

StarUML is a powerful and versatile tool that can help you design and develop software systems using UML and MDA. It supports many diagram types such as class, use case, sequence, activity, state machine, component, deployment, and more. You can also generate code from your models or reverse engineer existing code into models. StarUML supports various programming languages such as Java, C#, C++, Python, Ruby, PHP, and more.

However, StarUML is not the only software modeling tool available in the market. There are other alternatives that you can try if you are looking for different features or prices. Some of them are:

  • Visual Paradigm: A comprehensive software design tool that supports UML, BPMN, ERD, DFD, SysML, ArchiMate, and more. It also offers agile development tools such as user story mapping, sprint planning, task management, and Kanban board. You can download a free community edition or buy a professional edition with more features.
  • Enterprise Architect: A high-performance modeling tool that supports UML, SysML, BPMN, ArchiMate, TOGAF, and more. It also offers code engineering, simulation, testing, debugging, documentation, and project management tools. You can download a trial version or buy a license with different editions and prices.
  • UModel: A user-friendly modeling tool that supports UML 2.5 and integrates with Visual Studio and Eclipse. It also offers code generation, reverse engineering, synchronization, documentation, and validation tools. You can download a free trial version or buy a license with different editions and prices.

These are just some of the software modeling tools that you can use for your projects. You can compare them and choose the one that suits your needs and preferences best. Remember that software modeling is an important skill for any software developer or engineer. It can help you communicate your ideas clearly, design your system effectively, and develop your code efficiently.
