Features
Getting things done efficiently.
Folder compare, at any size
Fast recursive directory diff.
Edit both sides
Edit either file directly in the viewer, then save left or right independently, just like in vscode.
Custom file matching
Pair differently-named files by regex, a JS rule, or matching terms — save the rule and reuse it next time.
Respects .gitignore
Reads your .gitignore automatically — including nested ones — plus any custom ignore patterns you add on top.
