Moderne is a developer collaboration platform for automated code refactoring and analysis at mass scale. The platform enables development teams to migrate, maintain, and secure source code with speed and accuracy across thousands of repositories at once. Why just scan for issues when you can find and fix all at once? Code remediations and upgrades that can take many months of manual work can be done in minutes. Why undergo manual, expensive impact analysis projects on your codebase? Automate data collection and visualization to understand your code like never before. Why be stuck with older, unsupported software components? Automate your migrations to give your business the agility and innovation it's been missing! The Moderne refactoring system also works with AI large language models (LLMs) to support mass-scale code transformation and analysis tasks—enabling greater efficiency and accuracy for using AI across large codebases. Moderne is the creator of the OpenRewrite automated code refactoring open source project, and scales OpenRewrite recipes across thousands of repositories and millions of lines of code.
