What is Morph by Modelcode?
Morph migrates a codebase from one stack to another: Python 2 to 3, Java 8 to 21, Ada to C++, COBOL to Java, AngularJS to React, or a monolith to microservices. It analyzes the repositories and writes a Project Spec that a human approves before any code is generated. The migration runs in milestones, each delivered as a pull request through normal code review. Agents generate functional tests that run the original and migrated applications side by side and compare their outputs.

Morph by Modelcode FAQ
How does Morph handle migrating a monolithic application to microservices?
Morph analyzes the repository and writes a Project Spec that a human approves before any code is generated. The migration runs in milestones, each delivered as a pull request through normal code review. Agents generate functional tests that run the original and migrated applications side by side and compare their outputs.
What kind of human oversight is required during a migration with Morph?
Morph requires a human to approve the Project Spec before any code is generated, ensuring the migration plan is reviewed upfront. Each milestone is delivered as a pull request through normal code review, so every change is reviewed by the team before merging.
Which teams benefit most from using Morph for stack migrations?
Teams responsible for modernizing legacy codebases, such as those migrating from COBOL to Java or AngularJS to React, benefit most from Morph. Engineering teams that need to maintain output correctness during large-scale refactors will find Morph's output-comparison tests valuable.
How is Morph priced for teams with different usage levels?
Morph is available on a free tier, with paid plans for more usage and features. The free tier allows teams to start migrations without upfront cost, while paid plans unlock additional capacity and capabilities.
Can Morph verify that the migrated code produces the same results as the original?
Yes, Morph generates functional tests that run the original and migrated applications side by side and compare their outputs. This ensures the migration preserves correctness without requiring manual testing of every scenario.
How does Morph ensure that each migration step is reviewed before proceeding?
Morph writes a Project Spec that a human must approve before any code is generated. The migration then runs in milestones, each delivered as a pull request through normal code review, so every change is reviewed before it is merged.
Does Morph support migrations between programming languages like Ada to C++?
Yes, Morph supports cross-stack migrations including Ada to C++, COBOL to Java, Python 2 to 3, Java 8 to 21, and AngularJS to React. It analyzes the repositories and generates a Project Spec for each migration.
How does Morph integrate with a team's existing code review process?
Morph delivers each migration milestone as a pull request, allowing teams to use their normal code review workflow. This means the migration fits into standard development practices without requiring new tools or processes.
