OSDN, formerly SourceForge.JP, is a website for open source projects. It provides source code repositories and web hosting services. Most features are similar to SourceForge which acts as a centralized location for open source software developers. The OSDN repository hosts more than 5,000 projects and more than 50,000 registered users. Registered software is mostly specialized for Japanese use, such as input method systems, fonts, and so on, but there are popular applications like Cabos, TeraTerm, and Shiira.
