Calligra Suite is a free art (graphics creation) & office productivity suite that supports GNU/Linux, MS Windows and Mac OSX. It’s originally based on the KOffice suite and is still under heavy development. And few hours ago the developers announced the 2.4 Beta 5 release.
It’s more than just an office productivity suite as it comes with individual applications such as a Word Processor called “Words”, presentation creation tool called “Stage”, spreadsheet creation app called “Tables”, flow charts & diagram creation utility called “Flow”, a database management app called “Kexi” and project management tool called “Plan”.
But that’s for office related applications, as said before Calligra consists of comprehensive set of tools thus it even includes powerful graphics creating apps such as “Krita” and a vector graphics creator called “Karbon”.
For the GNU/Linux (or KDE users specifically) these two apps are not new as they’ve been used by KDE for a long time now.
Another feature of Calligra suit is that it even has a Mobile device optimized (redesigned UI to suite small/touch screens etc) version as well.
So if you’re looking for a powerful free alternative to MS Office then LibreOffice is one of the best but when considering its features and cross-platform compatibility Calligra suite seems like a powerful “opponent” rising out of nowhere :).
If you can’t wait till they release the stable versions then you can learn more and download (including a “.msi” installation wizard for Windows, which is about 155MB) it from this Calligra Suite home page.
In their home page you’ll also find instructions on how to install it in many major GNU/Linux distributions. But for Ubuntu 11.10 Oneiric Ocelot users can install Calligra Suite by simply adding the below PPA (thanks to Paulo Dias) to your system.
For that as usual, open a Terminal and type the below commands.
sudo apt-add-repository ppa:paulo-miguel-dias/peppa
sudo apt-get update
sudo apt-get install calligra
For other users, although I’m not sure whether Calligra has packages for older versions of Ubuntu such as 11.04 Natty Narwhal, 10.10 or 10.04 but according to this KDE userbase page, perhaps you might be able to install it in those versions as well.
But please remember that it’s still at testing stage thus not recommended to be used under professional environments. Good luck.
