Editors' Review Staff Nov 8, 2008
If you develop software for a living, you know it isn't hard to find free differencing tools. But if you do a lot of diff/merge work, especially across platforms, it can pay to, well, pay. Guiffy is a Java-based diff/merge tool with serious muscle and a much easier, more intuitive interface than you'll find on any freeware package. Not only does it work with more than 150 file formats from several platforms (Windows, Linux, Unix, and Mac OS), it also provides a trustworthy three-way merge feature called SureMerge. Since merging sometimes forces developers to stop working until the postmerge code has been checked by hand, a "smarter" three-way merge can greatly reduce overall development time. In addition to using Guiffy as a stand-alone utility, you can incorporate it into your own change-management products. Still not convinced? Compare Guiffy with its competitors and see for yourself; it's easy to spot the differences.

Developer's Description

Guiffy SureMerge is a visual file compare Diff tool, Merge tool, and Folder compare tool all-in-one that makes comparing, merging, and upgrading sources as easy and reliable as possible. Guiffy comes with: command line interfaces, an API package, Eclipse and NetBeans plugins and Explorer integration. Guiffy recognizes over 150 source file encoding formats (such as UTF8, UTF16, and many other multi-byte formats).

Advanced visual compare features include in-line difference highlighting and syntax highlighting for more than 20 source code languages. Our Trustworthy 3-way merge, SureMerge, was designed from day 1 to avoid all the problems that plague other 3-way diff based merge tools. SureMerge surpasses all other merge tools with its intelligent hybrid algorithms and ease-of-use. See our SureMerge White Paper which includes test kit files for evaluating 3-way merge tools. Guiffy is implemented entirely in Java with a Swing GUI.
