Best Code Refactoring Tools in 2026
Updated
In short: ReSharper is ranked #1 of 22 as of 4 October 2026, ahead of Sourcery and ast-grep. The best-ranked option with a free plan is Sourcery. The lowest first paid tier on this page is Sourcery at $12/mo.
Code refactoring tools can differ in the languages they support and the scale of changes they handle. Compare supported languages, AST-based analysis and refactoring scope, then look at batch refactoring for work across multiple code areas. AI assistance and deployment are additional criteria, while free-plan availability and “Paid from” help frame cost. The ranking begins with Moderne, ReSharper and CodeRush, followed by Scalafix. Consider the kinds of transformations your work calls for and which listed analysis, language and deployment capabilities suit your development workflow.
