Once modelled, several alternatives for the system as-is can be explored, each of one modelled as a different i* model. All the generated alternatives can be evaluated by defining and applying metrics over the i* models in order to establish which is the most appropriate for the system to-be.

All supported notations can be used together in an integrated manner, which means functional and non-functional requirements, agents, goals, softgoals, formal goals, and objects can be related as needed. The tool is implemented as a UML Profile that extends an open source UML modeling tool called StarUML. User models can be programmatically manipulated and reasoned about by external programs via APIs.

    • BIM-Tool is an Eclipse RCP Application that supports graphical modelling and analysis with the Business Inteligence Model language. The tool supports graphical modeling as well as automated reasoning techniques of two types: "what if?", and "is it possible?".
  • TAGOOn Tool
    • TAGOOn+ is a tool for the generation and integration of organizational ontologies that supports: 1) the automatic generation of organizational ontologies coming from models expressed with i*, Tropos and Service-Oriented i*, and 2) the automatic integration of those organizational ontologies with generic or domain ontologies.
  • WebREd-Tool
    • WebREd-Tool is a Model-Driven Tool conformed by a set of Eclipse plugins that have been developed to assist the designer in the early phases of a Web application development process. With the WebREd-Tool, the designer can specify the Web application requirements by using the i* goal-oriented framework. The WebREd-Tool assists the designer to compare different configurations of functional requirements, while balancing and optimizing non-functional requirements.
  • i*-REST
    • i*-REST is a set of web-services that allows creation/modification and visualization of i* SD models over a RESTful web API.
  • E4J
    • E4J: Editor for JGOOSE is a graph editor to support goal-oriented and/or agent-oriented modeling.
  • CreativeLeaf
  • Leaf 2.0
    • Leaf 2.0 is a browser-based tool which enables modeling of iStar 2.0 diagrams.
  • GrowingLeaf---BloomingLeaf
    • GrowingLeaf is a browser-based tool which enables modelers to reason models with goals whose evaluations change over time.
