Moderne

AI-powered large-scale code migration and remediation.

Moderne is an automated code remediation platform that uses AI agents and the open-source OpenRewrite framework to perform large-scale code changes across entire repositories — including framework migrations, security vulnerability fixes, dependency upgrades, and systematic refactoring. Rather than making changes file by file, Moderne operates across codebases at scale, enabling teams to apply consistent transformations to millions of lines of code without manual effort. It is aimed at mid-market and enterprise engineering organizations that maintain large or aging codebases where keeping up with security patches, framework upgrades, and technical debt is a significant ongoing burden. Moderne differentiates itself through its foundation in OpenRewrite, a well-established open-source project for automated code transformation, which provides a large library of pre-built recipes for common migration tasks.

Key Features

Large-scale code transformation: Applies code changes across an entire codebase or multiple repositories in a single operation, rather than requiring file-by-file manual editing or scripting.
OpenRewrite integration: Built on the OpenRewrite open-source framework, giving teams access to a large, community-maintained library of transformation recipes for popular frameworks and languages.
Automated security remediation: Identifies and fixes known security vulnerabilities in dependencies and code patterns at scale, helping teams stay current with security patches across large codebases.
Framework and dependency migration: Automates the mechanical work of upgrading frameworks, migrating to new APIs, or updating dependencies across an entire codebase — tasks that are time-consuming to do manually.
AI-assisted recipe generation: Uses AI to help generate custom transformation recipes for use cases not already covered by the existing OpenRewrite library.
On-premise deployment option: Supports on-premise deployment for enterprises that cannot send source code to a third-party cloud service.

Use Cases

For enterprises managing large legacy Java or JVM codebases: An organization running a large Spring Boot or Java application needs to upgrade framework versions and address accumulated security vulnerabilities — Moderne applies the changes systematically across the entire codebase in a fraction of the time it would take manually.
For platform engineering teams enforcing code standards at scale: An internal platform team wants to enforce updated coding standards or migrate away from deprecated internal APIs across dozens of repositories — Moderne’s transformation recipes apply the changes consistently without requiring each team to do it manually.
