A comprehensive office suite that includes a word processor, spreadsheet, presentations, and drawing tool. It is designed to be fully compatible with other popular office suites. The Document Foundation manages the development and upkeep of this software, which is a fork of OpenOffice.org. Download various language versions to meet your specific needs.
LibreOffice is a comprehensive and free suite of business applications. In addition to text documents, spreadsheet, and presentations, LibreOffice is capable of creating and managing drawings, databases, and formulae. In this way it offers an alternative not only to Microsoft Office but also to MS Paint, LaTeX, and database managing software.
Although I cannot claim to have used LibreOffice as extensively as one who uses it as a complete substitute for commercial products, my impressions of it are highly favorable. The interface may not be quite as slick as I've become accustomed to with modern Mac software, but the integration of basic image creation and database manipulation seems like the perfect complement of this software to me. Back in the days of Appleworks, bundling basic graphical software with text software was a no-brainer - how is it that no basic Mac application today is capable of permitting a freeform squiggle? Databases, perhaps, aren't quite as useful to the average user, but the programmer in me rejoices at having an alternative to spreadsheets, one with the logic of a database built in rather than slapped on top.
LibreOffice is highly flexible and, what's more, appears to run faster than the free or commerical alternatives. I can't recommend enough that you give it a try and see if it suits your needs before spending hard-earned cash on the latest-and-maybe-not-greatest version of the industry standard.
Sam's Protip: If interface aesthetics are really that important to you, take a look at NeoOffice. It's designed specifically for the Mac, although the latest version is no longer available for free.
v4.0 [Jan 8, 2013]
Installation
General: new naming scheme
Starting with version 4.0.0, the LibreOffice installer files have a new naming scheme. The most important is that "LibO" is replaced by "LibreOffice" in the names - so if you uses scripts to download the packages, please update them to the new schema.
Linux deb and rpm:
please, read detailed instructions for different distributions
the Linux packages can be installed in parallel to LibreOffice 3.6, but not run simultaneously - documents will be opened in the version you've started first.
Windows:
If you notice undesirable interactions between LibreOffice and OpenOffice.org, please report this as a bug.
LibreOffice windows installers are signed by The Document Foundation.
All executable files and shared libraries in the LibreOffice installations are signed by The Document Foundation.
Duden Korrektor will work with this version only if you put the stlport_vc7145.dll from 3.6.x installation somewhere in your %PATH%. Note that you will have to have also MSVCR90.DLL installed on your system.
Mac:
Mac Intel packages are now signed by The Document Foundation, and should pass 10.8 Gatekeeper without intervention. Please report problems here as a bug.
Help files
The Windows multi-language installer as well as the langpacks do only contain localized UI. By default, LibreOffice uses online help - if you need help files on your disk, please install the helppack for your language. If there is no helppack for your language (because help has not been translated to your language), then you can install and use the English helppack or check the online help in any available language.
