Kaleidoscope 3 Makes a Comeback with New Tools, Redesigned Interface

Millstatt, Austria - A major new version of Kaleidoscope, long a popular tool for Mac software developers, has been released. Kaleidoscope aims to be the world's most powerful file comparison app. Anyone can easily compare different text files, images, and folders on their Mac and iPad. Version 3 updates the app design for Big Sur and Monterey, and introduces dark mode. It is the first major redesign in over eight years. It also adds support for Apple Silicon-based Macs.

Kaleidoscope 3 also includes many additional new features and enhancements. It runs natively on all Macs, including those based on the Apple M1 chip. New powerful filters make it even easier for developers to compare items in changeset windows. Usability has been significantly improved with redesigned text, file, and folder comparison tools.

Christopher Atlan, developer of LetterOpener since 2006, acquired Kaleidoscope in 2020, a tool that he relies on for finding changes in code and merging them. "As developers who have long been fans of Kaleidoscope, we are able to see its great potential," said Atlan.

Atlan emphasized that this is a long-term commitment. "It's great to be able to bring out a modernized version with new features," he said, "but with this new version, we make clear our commitment to Kaleidoscope's long-term development. In fact, we decided to finance the acquisition and development with a bank loan, rather than accept outside investment that expects a quick return. We have big plans for Kaleidoscope's future."
