Alchemy Catalyst Software localisation tool

Anaphraseus Open source - based on OpenOffice macro set, so you require OpenOffice.

AnyMem CAT tool From developers of TO3000. Pretty terrible.‘AnyMem is a user-friendly translation memory software. AnyMem is compact, stable, easy to learn and to use. AnyMem CAT engine fully supports Unicode and can work with any language pair without the need of external components, like .NET Framework or Java Virtual Machine, commonly required by other translation memory software.’
Apple Trans CAT tool
Araya Suite
Autshumato Built on top of OmegaT.
CafeTran CAT tool (grid-based) High-powered, multi-platform (Java); UI can feel quite confusing to newbies used to memoQ, Trados, Déjà Vu, etc.

Read this for a laugh:'em

Apparently, someone at Wikipedia has some sort of secret vendetta against CafeTran, or at least the CafeTran users trying to get it mentioned on Wikipedia, since no matter what we do, they delete it. Interestingly, pretty much every single other big CAT tool does have its own page on Wikipedia. I really love Wikipedia but some of its editors really are tedious pedants.

Cypresoft's TransSuite 2000
DejaVu (latest version: X3) CAT tool (grid-based) Was once the coolest CAT in town, but has sort of been dying a slow death for many years now. Atril has been promising version X4 for like a thousand years. I'll believe it when I see it. Ghost ship.
DGT-OmegaT CAT tool (grid-based) ‘[…] DGT-OmegaT project, a fork of OmegaT, developed by the Directorate-General for Translation of the European Commission.’

Very interesting branch of the open source OmegaT, developed by the EU translation people. If I was forced to use an open source CAT tool, I’d probably use this. Due to some weird legal/ethical issue, they have a very generic domain:

ENLASO Localization tool Internal tool. This RWS (Enlaso) software localisation suite contains Rainbow (a file and code converter), Horizon (a document comparator) and album (an enhanced paper press).
Felix CAT tool (Word-based) Discontinued. Made open source a while back after developer got sick and couldn't continue active development. Still very interesting as it takes a novel (Word-based) approach involving interactive segmentation.
Fluency Translation Suite CAT tool Strange. Not sure if Americans should be allowed to make CAT tools ;-)
ForeignDesk Development stopped around 2002.
Fortis Révolution
Fortis Translation suite 3.0
FoundCAT Very strange. ‘FoundCAT is a free, open source tool that aims to help you improve your language skills by performing or reviewing translations of any language combination, or for translations into simple versions (i.e. Simple English as found on Wikipedia). FoundCAT offers advanced CAT (Computer-Aided Translation) features such as a Term Bank (a turbo glossary), Translation Memory (TM) and multiple Machine Translation (MT) APIs. You could start by uploading your favorite Wikipedia page. ’

Langage Studio

Lilt Online CAT tool w/ adaptive MT; its adaptive MT implementation is cool, but its MT engine isn't as good as Google Translate

Lionbridge Translation Workspace:
Logoport Logoport is an online TM and translation system from Lionbridge, a world leader in translation. Logoport allows you to set up large work groups. With open standards, Logoport supports the zliff format. The system integrates all automated translation engines directly linked to the Lionbridge vocabulary base.
MateCat Online CAT tool Free, online CAT tool developed by, who also made MyMemory, a gigantic translation memory with “4,846,362,480 human contributions”, and counting.
MemoQ WebTrans
memoQ CAT tool Had gotten too heavy/slow to use comfortably. UI was unresponsive, scrolling through long list ​in Translation results window too slow. However, the latest version seems to have improved and I can recommend it again. So many things just work in memoQ, which are permanently bungled in SDL Trados Studio. Just wish more agencies would choose memoQ instead of Studio.

Currently my go-to CAT tool.

Memsource CAT tool Pretty good (for an online tool). Pity it doesn't have proper support for SDL Trados packages. Also, I really like its UI/layout, which (as far as I can tell) was copied from memoQ.
MetaTexis MetaTexis is a CAT software that works with Word. It can read and process Trados and Wordfast documents and can also use the Trados and Workbench memory manager.
Multilizer Software localisation toolName Development seems to have stopped around 2015.
Nib Translate
Okapi tools
Olifant TMX editor Very old now, although it still works well. The developers have been so-called developing a new version for a long time now, but not very actively. In fact, I doubt they will ever finish it. The new version was supposed to be available from:

There is an alpha version available somewhere online, but it doesn’t work at all yet. I recommend the Heartsome TMX editor (also abandoned) instead. See info above.

OmegaT CAT tool (see also: DGT-OmegaT; A fork of standard OmegaT created by EU DGT)
Open Language Tools
Pootle Dedicated to online clients, Pootle acts as an online back office. The translation is done directly online and the tool communicates statistical information. However, there are two major disadvantages: the translation time is significantly influenced by connection quality and it is not possible to use a CAT tool. This therefore results in time wasting and an increase in the cost of translation.
QA Checker
Qt Linguist ‘Qt is a powerful portable development environment. Qt applications are easily translatable. Developers typically write their applications in English but all strings which are visible to the end-user can be automatically grabbed and stored in translation files with suffix .ts. See more details here.The translation files are then passed to various translators who are fluent in the target languages. Using a user-friendly tool, Qt Linguist, the translators produce the translations from the English strings in their native language.’ (src)

SDL Trados Studio OMG, where to begin? ‘Studio’ has been the so-called ‘market leader’ for a while, which isn’t really fair as it is one big mess. Very powerful aspects, and zillions of functions, but a gigantic pile of legacy crap held together by chewing gum and a shoestring.
