Ohloh is a free, public directory of Free and Open Source Software (FOSS) and the contributors who create and maintain it. Ohloh Code is a publicly available, free code search site that indexes most of the projects in Ohloh.

Ohloh is not a forge or code repository — it does not host projects and code. Ohloh is a directory, a community, and analytics and search services. By connecting to project source code repositories, analyzing both the code’s history and ongoing updates, and attributing those updates to specific contributors, Ohloh can provide reports about the composition and activity of project code bases, and aggregate this data to track the changing demographics of the FOSS world.

Ohloh is editable by everyone, like a wiki. All are welcome to join and add new projects, and to make corrections to existing project pages. This public review helps to make Ohloh one of the largest, accurate, and up-to-date FOSS software directories available. Ohloh is owned and operated by Black Duck Software .
