Blue Brain Nexus

Blue Brain Nexus is an ecosystem that allows you to organize and better leverage your data through the use of a Knowledge Graph. In addition to the products listed here, you’ll find a rich ecosystem of libraries and tools.


The Blue Brain Nexus ecosystem encompasses a broad range of capabilities that are brought to you across three complementary products and a suite of utilities.

Nexus Fusion

Enabling Collaborative Data and Knowledge Discovery

Fusion is our extensible web application. It hosts different apps to accommodate various use cases. It comes by default with Studios (where you work with data), Admin (for managing the Nexus instance), and will soon support to organise your data activities. It runs on top of the Delta web services, and integrates neatly with our Forge python framework.
