Pick ast-grep if…
It suits developers who need syntax-aware search, linting, or bulk code changes across supported languages. Teams wanting advanced static-analysis information or one rule spanning multiple languages should note its stated limits.
Pick OpenRewrite if…
OpenRewrite suits developers maintaining repositories who want recipe-based migrations, security updates, or style changes through Maven or Gradle. It is most directly suited to work that can be handled one repository at a time.
