Download and install Binaries

Latest stable version for Linux, Windows, and Mac OS-X

If the "Install" button is not activated, then Download/Select buttons are activated to download and select an installation archive. After download, you can continue with "Install".

If the above download links fail, then download CBinstaller.jar from the CB-Forum. Note that the thin CBinstaller can also work with installation archives different from You can download them separately from SourceForge (see below) or from the CB-Forum and then pick them with the CBinstaller option "Select installation archive".

Some behavioral anti-virus tools could block CBinstaller from installing ConceptBase on your computer. You need to temporarily disable these tools or install ConceptBase manually as described in the installation guide.

Starting ConceptBase

Linux, (Mac OS-X): Add the ConceptBase installation directory to your search path, e.g.

export CB_HOME=$HOME/conceptbase
These two lines should also be added to your init file of your Unix shell, e.g. .bashrc if you are using bash. Start the ConceptBase user interface CBIva via the command
in a command window. Then start the server via the menu item File/Start CBserver. You can also start the CBserver in another command window via the command 'cbserver [options]'. Consult the user manual for instructions on how to interact with the system. The tutorial on metamodeling is a good starting exercise as well.

Windows, Mac OS-X: We currently do not ship binaries of the CBserver for Windows and Mac OS-X. However, is fully functional on these platforms by connecting to a public CBserver hosted at University of Skövde. This public CBserver is pre-configured to be used for Windows and Mac OS-X installations. You can also configure your ConceptBase installation to use another public CBserver, e.g. installed and running on a Linux server in your local network. Under Windows, you can start CBIva by double-clicking the file cbiva.bat in the installation directory c:\conceptbase. You can also use a Windows command window to start it.

Raspberry Pi 2/3 under Raspbian (experimental): runs fine on a Raspberry Pi 2 under Raspbian. You can download a Raspbian image preloaded with ConceptBase from SourceForge. The README file contains instructions on creating an SD card from this image.

Configuring your desktop for ConceptBase

You can configure your desktop to support the ConceptBase file formats, in particular the graph file format '*.gel'. ConceptBase graph files store the graph diagrams including layout information and all Telos sources (object definitions) belonging to the graph. Whenever you start-up a graph file, it will connect either to a local or public CBserver to provide you with the query and update capabilities of the CBserver. See here for details.
