CodaLab Competitions is a powerful open source framework for running competitions that involve result or code submission. You can either participate in an existing competition or host a new competition. Most competitions hosted on CodaLab are machine learning (data science) competitions, but CodaLab is NOT limited to this application domain. It can accommodate any problem for which a solution can be provided in the form of a zip archive containing a number of files to be evaluated quantitatively by a scoring program (provided by the organizers). The scoring program must return a numeric score, which is displayed on a leaderboard where the performances of participants are compared.
To see CodaLab Competition's in action, visit codalab.lisn.fr.

If your competition needs extra computational power, you can easily add to the backend of the public CodaLab instance your own server(s) to process participant submissions.

This section explains how to run your own CodaLab instance (front-end and back-end). This allows you to customize CodaLab and have full control and full privacy. We prepared for you a re-usable AWS virtual machine image (called AMI), already pre-configured, thus easier to install. You can also install CodaLab from scratch on your own server. Before you venture into doing this, check "Customizing your website" in section 2.1 and the previous section, which may suffice to customize CodaLab for your needs.
Developers should first go through section 2.3.
