NZBKing has 3500 newsgroups crawled with up to 60+ petabytes of content. They offer 4000+ retention days of binary, and it is one of the longest we know for a free account.

Like other NZB sites, NZBKing does not host files on its website. The website is not automated, and even NZBKing promotes the use of a dedicated newsreader as an essential tool in downloading files.

NZBKing has a custom interface and is written in a Python language. The indexing is created by a Sphinx database, which indexes up to 10-15 MB of text per second. This search server is written in C++ and it works on Linux, macOS, Solaris, Windows, and more.

Ease of Use

Once you’ve entered their website, you can easily find the search bar to type the keyword you want to find. The advanced search engine (experimental) is an option for you to use, and you can sort by its file type, group, poster, date, size, etc.

Membership Levels

NZBKing is free to use.

Though NZBKing uses a rather complex algorithm to search for the content of the file, they prove to be a source of quality NZBs. They constantly upgrade their service and offer users unique and competitive features at no cost at all. For a free and open NZB site, NZBKing definitely has a lot of good things going for them and is certainly worth considering as your go-to indexer.
