Welcome to Codalab Competitions and Codabench group. You can share announcements and general discussions about the project here. This forum is not for bug reports (see below).

We are an international collaboration seeking to support scientific competitions (challenges) by making publicly available software tools facilitating their organization.

Codabench

- Open source project: https://github.com/codalab/codabench

- Public instance: https://codabench.org

The servers can be used free-of-charge for legitimate users accepting the Terms-of-use. This forum is for users, competition organizers, and developers, to exchange views and offer or receive help. Companies offering paid services to help competition organizers put together competitions are welcome to post their adds.
