}How it works
Three steps to cleaner code
PatternIO integrates seamlessly into your development workflow. No complex setup required.
Connect your project
Point PatternIO at your Java project directory or repository. Works with Maven, Gradle, and standalone projects.
Analyze architecture
Our engine scans your codebase for code smells, anti-patterns, and identifies existing design patterns in use.
Refactor with guidance
Get actionable suggestions with pattern-based refactoring strategies tailored to your specific code context.
Built for teams
For Java developers & teams
Everything you need to maintain a healthy, well-architected Java codebase.
Code Smell Detection
Identifies God Classes, Long Methods, Feature Envy, Data Clumps, and more.
Pattern Recognition
Detects existing GoF design patterns already present in your codebase.
Smart Suggestions
AI-enhanced refactoring recommendations with confidence scores.
Health Scoring
Get an overall architecture health score that tracks over time.
Team Collaboration
Share analysis results and track improvements across your team.
Secure by Design
Your code never leaves your environment. Token-based CLI access only.
Pattern catalog
Design pattern library
Strategy
Define a family of algorithms and make them interchangeable at runtime.
Observer
Establish a subscription mechanism to notify multiple objects about events.
Factory Method
Define an interface for creating objects, letting subclasses decide the type.
Builder
Construct complex objects step by step with a fluent interface.
Adapter
Convert an interface into another interface that clients expect.
Decorator
Attach additional responsibilities to an object dynamically.
Integration
CLI & IDE integration
Use your personal API token to run analyses directly from the command line or integrate with your CI/CD pipeline. IDE plugin support is coming soon.
Command Line Interface
Run analyses from your terminal with a single command.
IDE Plugins (Coming Soon)
IntelliJ IDEA and VS Code extensions for real-time analysis.
