CubesViewer - OLAP Visual Viewer and Explore Tool


CubesViewer is a visual, web-based tool for exploring and analyzing OLAP databases served by the Cubes OLAP Framework.

CubesViewer can be used for data exploration and auditory, generation of reports, chart designing and embedding, and as a (simple) company-wide analytics application.

CubesViewer is a visual interface for the open source Cubes server (an OLAP server in Python). Purpose is to keep it simple while leveraging the web services provided by Cubes.

See it live: CubesViewer site.


  • Dimension hierarchies, date filtering
  • Several charts and diagrams can be created
  • Explore, create data series, draw charts, see raw facts
  • Export data and images
  • Responsive design, tablet friendly
  • Undo / redo
  • Views can be embedded in other web sites
  • User Interface allows for multiple views on-screen
  • Optional multi-user server-side backend for saving/sharing views

Online Demos


Latest CubesViewer stable release is 2.0.2:

CubesViewer Server already includes the CubesViewer library so you just need that package if you plan to deploy the server-side application.

If you do modifications to the project, cloning both repositories via git is encouraged, so you can easily contribute your fixes and improvements back.


CubesViewer consists of two parts:

CubesViewer client is an HTML5 application that runs on any modern browser. It can run without server side support. Simply download the package and open html/studio.html in your favorite browser. Views can also be embedded in other sites.

CubesViewer also features an optional server side application which provides a full web application and supports features like sharing/saving views. This project lives on a separate repository: CubesViewer Server (not to be confused with Cubes Server itself).

You need a configured and running Cubes Server version 1.0.x or later. Your Cubes model may use some extra configuration if you wish to use features like date filters and range filters (see Documentation below).

For CubesViewer clients to connect to Cubes server ("slicer"), your Cubes server possibly needs to allow cross origin resource sharing (CORS). To enable it, add allow_cors_origin: * (or a more restrictive setting) under the [server] section of the slicer.ini file.

For further information, see the Documentation section below.


This tool allows users to inspect the different dimensions, measures and aggregated data in different ways, allowing you to build tables and charts based on the analytical data available from the server.
