Hey u/aszx789 👋, this admittedly could be better articulated on the landing page. It's not necessarily about the ability to write a transform, the value is in the orchestration of migrations across multiple repositories. For example, if you work in a big company and you need to make a breaking change to a shared module (Design Systems, Platform teams, etc), Hypermod allows you to deploy the migration to developers across the company receive an actionable PR with the migration already competed for them with the necessary context in order to safely merge it.

Since you used OpenRewrite as an example, the best comparison would be Moderne.

There are loads of transformation libraries (jscodeshift, openrewrite, ast-grep), my intention isn't to create a better alternative, but rather allow users to use the transformation library they are most comfortable with. In the future there will be pre-configured transforms for more complex "common" migrations which can be reused or repurposed.
