Backed by the growing OpenRewrite community collaborating to stop the mayhem of migrations and vulnerability remediation. Easily customize your own code migration and modernization actions in addition to over 2,800 open-source recipes.
Safe, deterministic transformations — not regex or guesswork
Native SCM integration (GitHub, GitLab, Bitbucket)
Org-level PR management and progress dashboards
Scaling OpenRewrite means running OpenRewrite recipes across thousands of repositories simultaneously rather than one at a time. Moderne is the platform built specifically for this — providing the orchestration, auditability, and multi-repo management that enterprises need to apply OpenRewrite transformations at the speed and scope their codebase requires.
OpenRewrite is the open source refactoring framework and recipe ecosystem. Moderne is the enterprise platform built on top of it by the same creators. Where OpenRewrite handles the transformation logic, Moderne adds the infrastructure to run those recipes across thousands of repositories, manage pull requests at the organizational level, track progress through dashboards, and apply changes with full auditability.
Enterprise teams use Moderne to automate large-scale code modernization across their entire codebase. Common use cases include Java version upgrades, Spring Boot migrations, CVE and security vulnerability remediation, dependency management, and framework standardization — all executed through OpenRewrite recipes and delivered as reviewable pull requests.
Yes. Moderne uses the Lossless Semantic Tree (LST) to ensure every transformation is deterministic and semantically accurate rather than relying on regex or AI guesswork. Every change is delivered as a clean, reviewable pull request so engineering teams can validate before merging. This makes it safe to run at enterprise scale across thousands of repositories.
Yes. In addition to the 2,800+ open source recipes available in the OpenRewrite community, Moderne supports custom recipe authoring so enterprises can encode their own internal standards, migration patterns, and modernization workflows. Custom recipes can be applied at the same scale as community recipes across the entire repository estate.
What traditionally takes months of manual engineering effort can be completed in days or weeks with Moderne. Because OpenRewrite recipes run across thousands of repositories in parallel and deliver changes as ready-to-review pull requests, teams spend their time reviewing and merging rather than writing migration scripts or hunting down deprecated patterns one file at a time.
When a new CVE is disclosed, Moderne can apply the relevant OpenRewrite fix recipe across your entire codebase in a single campaign. Rather than triaging and patching repositories one by one, security and engineering teams get a complete picture of exposure across every repo and can push remediation pull requests organization-wide. What used to take months now takes days.
No. Many enterprise teams come to Moderne without any prior OpenRewrite experience. Moderne provides access to the full library of community recipes, a platform to discover and preview what changes would look like before running them, and the tooling to manage the rollout across your organization. OpenRewrite knowledge helps for custom recipe authoring but is not required to get immediate value from the platform.
