wikiCalc (now called SocialCalc)
Gnumeric — for Linux. Started as the GNOME desktop spreadsheet. Reasonably lightweight but has very advanced features.
KSpread — following the fork of the Calligra Suite from KOffice in mid-2010, superseded by KCells in KOffice and Sheets in the Calligra Suite.
LibreOffice Calc — developed for MS Windows, GNU/Linux, BSD and Apple Macintosh (Mac) operating systems by The Document Foundation. The Document Foundation was formed in mid-2010 by several large organisations such as Google, Red Hat, Canonical (Ubuntu) and Novell along with the OpenOffice.org community (developed by Sun) and various OpenOffice.org forks, notably Go-oo. Go-oo had been the "OpenOffice" used in Ubuntu and elsewhere. Started as StarOffice in the late 1990s, it became OpenOffice under Sun and then LibreOffice in mid-2010. The Document Foundation works with external organisations such as NeoOffice and Apache Foundation to help drive all three products forward.
NeoOffice Calc — for Mac. Started as an OpenOffice.org port to Mac, but by using the Mac-specific Aqua user interface, instead of the more widely used X11 windowing server, it aimed to be far more stable than the normal ports of other suites.
OpenOffice.org Calc — for MS Windows, GNU/Linux and the Apple Macintosh. Started as StarOffice. Sun changed the name to OpenOffice.org and developed a community of developers (and others) between the late 1990s and mid-2010. Oracle gave it to the Apache Foundation in 2011. IBM contributed their fork of OpenOffice.org, IBM Lotus Symphony, to Apache a few weeks later.
Siag — for GNU/Linux, OpenBSD and Apple Mac OS X. A simple old spreadsheet, part of Siag Office.
Sheets — for MS Windows, GNU/Linux, FreeBSD, Apple Mac OS X and Haiku. Part of the extensive Calligra Suite. Possibly still mainly for Linux, but ports have been developed for other operating systems.
