About Grit

Grit is an AI-powered tool for automated code migrations and upgrades. It uses AI to automatically migrate codebases from older versions to newer ones — upgrading React versions, modernizing deprecated APIs, replacing removed packages, and fixing breaking changes at scale. Grit's migration engine understands code semantics (not just syntax), so it makes contextually accurate upgrades rather than simple text replacements.
