JDownloader is a download manager, written in Java, which allows automatic download of groups of files from one-click hosting sites. JDownloader supports the use of premium accounts.[1] Some parts, but not all, of JDownloader are open source. In December 2009 the program's website was in the top 1000 visited websites of Spain.[2] The German online magazine, Chip.de designated it "newcomer of the year" in 2009, after it ranked among the top 50 most downloaded applications, with over half a million downloads in a year.[3]

Mid-2012 there were complaints that JDownloader's installer added adware without the user's consent.[4] The JDownloader installation contains AdWare according to several sources, including the developer's own forums.[5][6] There were further complaints mid-2014.

In June 2013, JDownloader's ability to download copyrighted and protected RTMPE streams was considered illegal by a German court. This feature was never provided in an official build, but was supported by a few nightly builds.[7]

In 2011, JDownloader was superseded by its successor, JDownloader 2. While support for the original JDownloader still exists on forums, the official site only lists JDownloader 2.

License

Contrary to the license, some source files are not publicly available. The developers stated that the license may change—the program will remain open source, but will get a license which allows closed-source parts.

Features

Specified features:[8]

The user-specified download links are split into packages to enable individual pausing and continuing of downloads. The program can be configured to unpack split RAR archives automatically after all parts have been downloaded.

JDownloader supports "waiting time" and CAPTCHA recognition on many file hosting sites, enabling batch downloads without user input.[10] Premium users of one-click-host sites can use multiple connections per downloaded file, which increases download speed in most cases. It also supports Metalink, a format for listing multiple mirrors. Software updates and minor patches are released frequently; by default JDownloader updates itself upon initialization. As of 2014 JDownloader uses a continuous deployment system where modifications to the program code (e.g. adapting a plugin to changes in a download site's HTTP API) can be released within minutes.[9] For the beta version, frequently occurring errors in plugins are detected via automated error reports (leaving out some privacy-sensitive data including the user's IP address and the name of the downloaded file).[9]
