Facts

Purpose: Alloy is a language for describing evolving structures, and the Alloy Analyzer explores models by finding structures that satisfy constraints or counterexamples to properties.alloytools.org · 4 Oct 2026
Modeling: Alloy models describe sets of structures that may evolve over time, such as security configurations or switching network topologies.alloytools.org · 4 Oct 2026
Visualization: The Analyzer displays structures graphically, and their appearance can be customized for the domain.alloytools.org · 4 Oct 2026
Temporal analysis: Alloy 6 adds mutable state, temporal logic, and temporal model checking; the latter relies on NuSMV or nuXmv installed by the user and available in PATH.alloytools.org · 4 Oct 2026
Bundled components: The self-contained executable includes the Pardinus/Kodkod model finder, SAT solvers, the standard Alloy library, tutorial examples, and source code.alloytools.org · 4 Oct 2026
API: The same JAR file can be incorporated into other applications to use Alloy as an API.alloytools.org · 4 Oct 2026
Platforms: The download page identifies Alloy 6.2.0 and says it includes a version for macOS High Sierra; it also describes running the JAR with Java.alloytools.org · 4 Oct 2026
Visualizer extension: Sterling is a web-based Alloy visualizer customizable and extendable with JavaScript, with graph and table views.alloytools.org · 4 Oct 2026
Applications: The project links applications including Alloy*, a Ruby embedding, a bounded Java verifier, and a firewall security policy analyzer.alloytools.org · 4 Oct 2026
Community support: The project is maintained by volunteers, with Discourse as its main discussion venue and Stack Overflow as the venue for precise questions monitored by developers.alloytools.org · 4 Oct 2026
Security use: The project says Alloy has been used to find holes in security mechanisms and describes modeling security configurations of web applications as an example.alloytools.org · 4 Oct 2026
Origin: Alloy was created in MIT's Software Design Group.alloytools.org · 4 Oct 2026
Release: The site lists Alloy 6.2.0 as the latest release, dated 2025-01-09.alloytools.org · 4 Oct 2026
