When reshaping existing code, the right tool can depend on the languages involved and the scale of changes you need to make. Compare supported languages, AST-based analysis, refactoring scope, and batch refactoring, along with AI assistance and deployment options. Free-plan availability and paid-from pricing add another practical dimension. The ranking starts with Moderne and PolyglotPiranha, followed by ReSharper and CodeRush; Scalafix, DMS Software Reengineering Toolkit, Coccinelle, and OpenRewrite also appear among the entries. Consider which languages and types of transformations matter to you, then weigh how each tool’s listed capabilities align with that work.
