MateCat is a free, open source software released under the LGPL license.

Its source code is available at:

The key proprietary part of is the Translation Memory (which was translated using some Artificial Intelligence). Other functions of the website are provided by the open source version.

Also check for other software and benchmarks from the EU-funded projects Moses and MateCat.

The software available on is a proprietary version of a fully customizable open source version, which is the result of a 3-year research project led by a consortium composed of the international research center FBK (Fondazione Bruno Kessler), the University of Edinburgh, the Université du Maineand Translated srl.

Hardware requirements

If you just want to test MateCat on a few million words you will need 1 server with:

  • Storage: 50GB
  • CPU: 2 core x 2.5 Ghz
  • RAM: 4GB

To manage 50M words per year of translation capacity, you will need 1 server with:

  • Storage: 1TB
  • CPU: 6 core x 2.5 Ghz
  • RAM: 32GB

If you need to manage up to 200M words per year, you can do it using 4TB of storage, 12 CPU core, and 64GB of RAM and placing the MySQL database on a separate machine (easy to do with the MateCat config file). For handling more than 200M words per year you will need to add a load balancer in front of the web servers and databases. Databases will need a master-master replica schema. This will require an experienced LAMP and scalability engineer.

Getting started with fast setup: use MateCat in a virtual machine

MateCat ships as a full fledged, self-contained appliance you can get up and running in minutes.
We provide a virtual machine image that comes with MateCat preinstalled. The image is compatible with VirtualBox software (get VirtualBox here, first:

Download the virtual machine

You can download the MateCat Virtual Machine image (.ova) from the following URL: matecat_latest.ova (~2.3 GB).

Once the image has been downloaded, and after VirtualBox software has been installed, double click on the image file to start VirtualBox’s import wizard . If you feel unsure about what to input in the various panels, click your way through the wizard by pressing “Next>” button; the default parameters are good enough for an average machine.

Start the virtual machine

Open VirtualBox and start MateCat virtual machine.
After some loading (depending mostly upon the performance of your machine), you should be presented with a desktop environment with a welcome message.
To start MateCat, click on MateCat icon on the left bar, in the upper-left corner of the screen.
We have included some files on the desktop to let you experiment with MateCat.

Important Notice:Altough there is no login request or screen lock, in case the virtual environment prompts you with credentials input, the virtual machine credentials are:

  • username: matecat
  • password: matecat


That’s all for the fast setup. Enjoy Matecat!
