CinePaint is currently available for UNIX and Unix-like OSes including Mac OS X and IRIX. The program is available on Linux, Mac OS X, FreeBSD and NetBSD. Its main competitors are the mainline GIMP and Adobe Photoshop, although the latter is only available for Mac OS X and Microsoft Windows. Glasgow, a completely new code architecture being used for CinePaint, is expected to make a new Windows version possible and is currently under production. The Glasgow effort is FLTK based. This effort appears to have stalled.
