What Can Polarity Do? Key Features
Intelligent Planning
Polarity performs deep research on your codebase, project documentation, and relevant web resources to identify issues in your PRs. It analyzes files across your repository, researches best practices online, and reviews project documentation to create comprehensive fix plans.
Parallel Execution
Polarity uses a fleet of worker agents with intelligent sharding to handle complex tasks efficiently. The system spawns sub-workers for specialized tasks like UI regression sweeps, accessibility audits, API contract diffs, and load testing, enabling parallel processing of multiple aspects of your code.
Comprehensive Verification
Polarity runs unit, integration, and end-to-end tests to verify code changes. It offers optional sandbox mode for isolated environment testing with full web server and API testing capabilities. The system provides detailed reports on test results, code coverage, security scans, and performance metrics.
Security & Configuration Monitoring
Polarity proactively identifies potential security vulnerabilities and configuration issues before deployment. It detects critical issues like debug mode enabled in production, security patches needed for dependencies, and other configuration problems that could impact production environments.
Codebase Modernization
Polarity automatically refactors legacy code, updates dependencies, and resolves technical debt. It helps keep your codebase modern and maintainable without slowing down feature development, with features like automatic dependency version checking and updating.
Enterprise-ready Infrastructure
Polarity offers production-ready infrastructure with SOC2 certification, zero data retention policies, single sign-on capabilities, and high-volume tiers. Enterprise features include comprehensive DPAs, SLAs, and high-capacity rate limits for large-scale operations.
Contextual Understanding
Polarity builds a complete understanding of your system by connecting to repositories, documentation, and infrastructure. It creates repository mappings, syncs documentation sources, connects to cloud providers and databases, and allows custom coding standards and guidelines.
Intelligent Indexing
Polarity automatically indexes your entire codebase, understanding dependencies, relationships, and architecture patterns. It creates a comprehensive knowledge graph for instant context retrieval, mapping files, packages, and their relationships within milliseconds.
Best Polarity Use Cases & Applications
Automated Code Review and Fixing
Engineering teams can use Polarity to automatically review every PR, identify issues, and implement fixes without manual intervention. This reduces code review burden on senior engineers and ensures consistent quality standards across all contributions.
Legacy Code Modernization
Companies with legacy systems can use Polarity to automatically refactor outdated code, update dependencies, and resolve technical debt. This helps maintain system reliability while freeing up developer time for feature work.
Security Compliance
Security-conscious organizations can leverage Polarity's automated security scanning to identify vulnerabilities in PRs before they reach production. The tool checks for debug modes in production, outdated dependencies with security patches, and other common security misconfigurations.
Rapid Prototyping with AI-generated Code
Teams using AI-generated code can rely on Polarity to transform experimental code into production-ready implementations. The system analyzes, refactors, and verifies AI outputs to meet organizational standards and best practices.
Continuous Integration Enhancement
Development teams can integrate Polarity into their CI/CD pipelines to add intelligent analysis and autonomous fixing capabilities. This goes beyond traditional testing by actively improving code quality throughout the development process.
How to Use Polarity: Step-by-Step Guide
Connect your repositories: Link your Git repositories, monorepos, and microservices to Polarity. The system will begin indexing your codebase to understand dependencies and architecture patterns.
Sync documentation and context: Import wikis, READMEs, internal docs, and connect your infrastructure (cloud providers, databases) to give Polarity complete system awareness. Define any custom coding standards or guidelines.
Submit a pull request: When you create a PR, Polarity automatically analyzes it by examining your codebase, researching relevant information, and reviewing project documentation to identify issues.
Review and approve fixes: Polarity presents a plan for fixing identified issues. Review the proposed changes and approve them for execution. The system can operate autonomously once approved.
Autonomous execution and verification: Polarity executes the approved fixes using parallel worker agents. It then runs comprehensive verification including unit tests, integration tests, E2E tests, security scans, and performance checks.
Deployment ready: Once all verifications pass, your PR is ready for deployment. Polarity provides detailed reports of all changes made and tests performed, giving you confidence in the production readiness of your code.
