What is Moderne OpenRewrite?
Moderne provides a platform for guided, large-scale code change, enabling organizations to operate software systems at the speed of AI agents. It builds the knowledge, discovery, and execution tools coding agents rely on to operate faster, more accurately, and at far lower cost across real-world software systems. Powered by the OpenRewrite Lossless Semantic Tree (LST), the platform offers a comprehensive context model for code, understanding and transforming code at scale.
The platform delivers a coordinated set of high-performance tools that coding agents use to understand software systems, discover relevant code, and safely execute large-scale engineering changes across enterprise environments. This includes deterministic framework, language, and dependency upgrades, bulk vulnerability remediation, and multi-repository change coordination. Moderne aims to free developers from tedious, time-consuming, and neglected tasks by providing continuous automated refactoring and analysis of source code at mass scale.

Moderne OpenRewrite FAQ
What is the Lossless Semantic Tree (LST) and how does Moderne utilize it?
The Lossless Semantic Tree (LST) is a compiler-accurate code model that serves as the foundation for Moderne's platform. It provides the industry’s most comprehensive context model for code, enabling precise, code-aware semantic analysis and transformation capabilities. Moderne uses the LST to power OpenRewrite automation, allowing for deterministic and reliable automated changes across repositories and organizations.
How does Moderne address the challenge of large-scale code remediation?
Moderne addresses large-scale code remediation by providing tools for bulk vulnerability remediation using verified, repeatable transformations. It allows for the execution of synchronized engineering changes across entire software portfolios with full traceability, ensuring that security updates and refactoring efforts are applied consistently and effectively across thousands of repositories.
Can Moderne integrate with existing AI coding agents?
Yes, Moderne is designed to provide coding agents with structured system context, high-speed semantic search, and deterministic execution infrastructure. It optimizes how coding agents access knowledge and execute changes, allowing agents to operate with shared intelligence, reduced token waste, and organizational governance across multi-repository environments.
What kind of economic impact can organizations expect from using Moderne?
Organizations can expect a dramatic reduction in agent token cost by improving tool-call efficiency and shifting work from GPU inference to CPU-based precomputation. This optimization leads to more cost-effective agent operations and a new point of engineering leverage.
How does Moderne ensure the safety and reliability of large-scale code changes?
Moderne ensures safety and reliability through its deterministic transformation architecture and the use of the Lossless Semantic Tree. It allows for coordinated changes with consistency, validation, and sequenced rollout across the organization, providing a unified view of software changes and enabling governed execution across thousands of repositories.
