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 Moderne if…

Moderne suits organizations coordinating software changes across many repositories, particularly teams managing upgrades, migrations, security work, or modernization. Its community version may suit people exploring open-source repositories and cross-repository search.
