Seashore is an open source image editor for Mac OS X's Cocoa framework. It features gradients, textures and anti-aliasing for both text and brush strokes. It supports multiple layers and alpha channel editing. It is based around the GIMP's technology and uses the same native file format.

However, unlike the GIMP, Seashore aims to serve the basic image editing needs of most computer users, not to provide a replacement for professional image editing products. Also, unlike GIMP, Seashore has an all-new Cocoa UI that will fit right in on Mac OS X.

Seashore was created by Mark Pazolli who led the project until the end of 2009.
