Moderne is an automated code modernization platform built on OpenRewrite that refactors thousands of repositories at once.
Moderne tackles the code maintenance work nobody schedules: framework migrations, security remediation and dependency upgrades across entire codebases. Built on the open-source OpenRewrite framework, it runs automated refactoring recipes across hundreds of repositories simultaneously and produces pull requests with consistent changes. AI assistance helps author new recipes and interpret results. Enterprises use it for Java-to-Jakarta migrations, CVE patches and style enforcement at a scale manual teams cannot touch.
Moderne is sold as an enterprise platform with pricing based on repository scale and deployment; the OpenRewrite framework itself is open source.
Large engineering organizations managing hundreds of repositories that need consistent, automated modernization.
Platform teams apply security fixes across hundreds of services in one campaign, and architects run framework migrations that would take quarters manually. Financial institutions remediate CVEs with auditable, automated pull requests.
Start with OpenRewrite recipes on one repository to see the transformation quality, then engage Moderne for multi-repo orchestration and campaign management.
The underlying OpenRewrite framework is free; the Moderne platform is enterprise-priced.
Yes — the platform integrates with git hosting and CI pipelines for automated runs.
Versus manual refactoring or IDE refactoring tools, Moderne operates at multi-repo scale; versus simple find-replace it performs semantic code transformation.
Java and the JVM ecosystem are the deepest, with growing support for JavaScript, Python and other stacks through the recipe ecosystem.
Yes — every transformation produces standard pull requests, so teams review and merge with their normal controls and CI checks.
An open-source refactoring framework whose recipes perform semantic code transformations — the engine underneath the Moderne platform.
Migration effort drops from quarters to campaigns, and consistent automated changes eliminate the drift manual refactoring leaves behind.
JVM languages lead, and the recipe ecosystem has expanded into JavaScript and Python with more stacks arriving over time.
Yes — the framework is open source; the Moderne platform adds orchestration and enterprise support.
