recognition on many file hosting sites, enabling batch downloads without user input. 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.

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.Thomas Rechenmacher
