What mergers is

mergers is a free visual diff and merge tool for comparing files and directories. It runs on Linux, macOS, and Windows, and supports two-way file comparisons with syntax highlighting as well as three-way merging to resolve conflicts. Directory comparisons scan recursively in the background. The tool can display uncommitted Git changes and be configured as Git's merge tool. It opens and applies .patch and .diff files, shows failed sections with conflict markers, and exports unified diffs. Editing features include inline word-level highlighting, find and replace, undo and redo, chunk navigation, and synchronized scrolling. File watching can reload changed content, and folder filters, directory copying, and deletion are also listed. Installation options are described for macOS, Linux, and Windows; building from source requires GTK4 and GtkSourceView 5 development libraries. The repository lists a GPL-2.0 license. The project warns that this is alpha-quality software and may damage files, corrupt data, or discard changes without warning, and advises keeping backups and using version control.
