The following is a list of spreadsheets.
Free and open-source software
Cloud and on-line spreadsheets

Sheetster – "Community Edition" is available under the Affero GPL

Simple Spreadsheet
Tiki Wiki CMS Groupware includes a spreadsheet since 2004 and migrated to jQuery.sheet in 2010.[1]
wikiCalc (now called SocialCalc)
Airtable - a spreadsheet-database hybrid, with the features of a database but applied to a spreadsheet.
Spreadsheets that are parts of suites
Gnumeric— for Linux.  Started as the GNOME desktop spreadsheet.  Reasonably lightweight but has very advanced features.[2]
KSpread— following the fork of the Calligra Suite from KOffice in mid-2010, superseded by KCells in KOffice and Sheets in the Calligra Suite.[3]
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.[4]
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.[5]
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.[6]
Siag— for GNU/Linux, OpenBSD and Apple Mac OS X.  A simple old spreadsheet, part of Siag Office.[7]
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.[8]
