microsoft/ApplicationInspector

Application Inspector is a static source code analyzer that uses a JSON-based rules engine to identify features and characteristics in code.

The tool addresses the need to quickly understand what functionality exists in a codebase without manual review. It works by applying pattern-matching rules defined in JSON format against source code to surface features of interest and other notable characteristics. This approach enables rapid scanning of components to answer fundamental questions about code composition and behavior.

Application Inspector suits teams evaluating third-party components before integration, tracking feature-level changes across versions, or conducting security assessments where understanding code capabilities is essential. It works across multiple programming languages through its rules-based detection system. The tool is particularly valuable in supply chain security contexts where you need to verify what a component actually does before bringing it into your project.

The project shows consistent maintenance with regular updates addressing bug fixes and rule improvements. Development activity demonstrates responsiveness to user-reported issues and ongoing refinement of the detection rules that form the core of the tool's functionality.
