JDownloader is a download manager, written in Java, which allows the automatic downloading of files and split files from one-click hosting sites such as RapidShare. JDownloader supports the use of premium accounts. Some, but not all, parts of JDownloader are open source.
In December 2009 the program's website was in the top 1000 sites by traffic from Spain. The German online magazine, Chip.de designated it "newcomer of the year" for 2009 after it ranked among top 50 downloads with over half a million downloads for the year.
From mid-2012 there were complaints that JDownloader's installer installed adware without the user's consent. The JDownloader installation contains AdWare according to several sources, including the developer's own forums. There were further complaints from 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.
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.
|This section relies too much on references to primary sources. (October 2012)|
- Versions run under (Microsoft Windows, Linux, Mac, etc.), and Java 1.5 or higher
- Can download several files simultaneously, over several connections
- Can automatically solve some CAPTCHAs with its own OCR module (JAntiCaptcha)
- Automatic extractor (including password list search) for RAR archives
- Decrypt RSDF, CCF and DLC Container files
- About 300 decrypt plugins for many services. For example, sj.org, UCMS, WordPress, and RLSLog.
- Supports "hoster plugins" for downloading from e.g. a specific one-click hoster (1230 as of 2014[update])
- Can automatically acquire a new IP address to save waiting time with hosts which limit downloads to one address (1400 routers supported)
- Integrated package manager for additional modules (e.g., Web interface, Shutdown)
- Theme support
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 the RapidShare "waiting time" and CAPTCHA recognition, enabling batch downloads without user input. Premium users of one-click-host sites can use multiple connections per downloaded file, which increases file 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[update] 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. 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).
