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.
