Morph is an enterprise code modernization platform from Modelcode that automates migrating codebases from one technology stack to another, such as upgrading Python 2 to Python 3, Java 8 to Java 21, translating Ada to C++, or moving a legacy framework to a modern one. It connects to your repositories and works through a controlled, human-in-the-loop workflow. You define the modernization goal and configure how the project builds, runs, and tests. Morph analyzes the repositories, documents their architecture, and produces a Project Spec that you review and approve before any code is generated. Once approved, the migration runs in milestones, each delivered as a pull request that goes through your standard code review and merge process. Morph runs functional tests to verify the behavior of each change, supports multi-repository projects where each repository has a defined role, and lets teams encode coding standards as Rules that apply across all milestones. Morph is designed to work alongside AI coding agents as an overlay that plans, executes, and verifies large-scale modernization across a codebase.
