Project MRI
Project MRI is a software analysis platform that enables developers to rapidly comprehend unfamiliar codebases. By uploading a ZIP archive of a repository (up to 100 MB), the service automatically generates a prioritized reading plan, identifying the five most critical files to review first. It supports popular web frameworks such as React, Next.js, Express, Django, Spring Boot, and Laravel. The tool produces an architecture diagram that visually maps system components and their interdependencies. Additionally, Project MRI provides a Risk Radar ranking files by complexity and dependency count, along with a weighted Repository Health Score (0–100) covering test coverage, code quality, architecture, and technical debt. An AI assistant is integrated to answer questions about the analyzed codebase. The service is designed for rapid onboarding, technical due diligence, and continuous codebase assessment.
