Open Hub or Black Duck Open Hub (formerly Ohloh) is a website which provides a web services suite and online community platform that aims to index the open-source software development community. It was founded by former Microsoft managers Jason Allen and Scott Collison in 2004 and joined by the developer Robin Luckey. As of 15 January 2016, the site lists 669,601 open-source projects, 681,345 source control repositories, 3,848,524 contributors and 31,688,426,179 lines of code.

In 2017, Black Duck Software (the company running the site) was acquired by Synopsys for $565 million, however it was spun out as a separate company again in October 2024.
