List of Usenet newsreaders
Usenet is a worldwide, distributed discussion system that uses the Network News Transfer Protocol (NNTP). Programs called newsreaders are used to read and post messages (called articles or posts, and collectively termed news) to one or more newsgroups. Users must have access to a news server to use a newsreader. This is a list of such newsreaders.
Types of clients
- Text newsreader – designed primarily for reading/posting text posts; unable to download binary attachments
- Traditional newsreader – text-capable newsreader which can also handle binary attachments, although not as efficiently as more specialized clients
- Binary grabber/plucker – designed specifically for easy and efficient downloading of multi-part binary post attachments; limited or nonexistent reading/posting ability. These generally offer multi-server and multi-connection support. Most now support NZBs, and several either support or plan to support automatic Par2 processing. Some additionally support video and audio streaming.
- NZB downloader – binary grabber client without header support – cannot browse groups or read/post text messages; can only load 3rd-party NZBs to download binary post attachments. Some incorporate an interface for accessing selected NZB search websites.
- Binary posting client – designed specifically and exclusively for posting multi-part binary files
- Combination client – Jack-of-all-trades supporting text reading/posting, as well as multi-segment binary downloading and automatic Par2 processing
