Seashore is a free and open-source image editor for macOS, similar to Photoshop/GIMP, with a simpler Cocoa user interface.[2][3] Seashore uses GIMP's native file format, XCF, and has support for a handful of other graphics file formats, including full support for TIFF, PNG, JPEG, JPEG2000, and HEIC and read-only support for BMP, PDF, SVG and GIF. Seashore offers fewer features than Photoshop/GIMP, but is intended to be easy-to-use and to run natively on macOS. It includes layers and alpha channel support, gradients and transparency effects, anti-aliased brushes, tablet support and plug-in filters.

After several years without maintenance, development was restarted by Robert Engels in 2017 to allow it to run on newer versions of macOS.[3] Seashore version 3.16 was released in December 2022 and is considered to be stable.[4]

The latest release is distributed via the Apple Mac App Store.[5][3]
