Diff Checker

Comparing code, configuration files, or data structures is a common developer task. Our Diff Checker provides a clean, intuitive interface to spot differences between two text or JSON inputs. Additions are highlighted in green, deletions in red, and unchanged content in gray. Perfect for code reviews, debugging configuration changes, comparing API responses, or validating data migrations. The side-by-side view makes it easy to understand what changed. Works entirely in your browser with no data ever sent to a server.
