Key Overview
- Index Going Back 4,000 Days – NZBKing indexes more than 11 years of Usenet articles, making it the deepest raw Usenet search tools still maintained. This makes it particularly valuable when searching for older articles that don’t appear on many curated indexers.
- Detailed NFO Previews – Search results frequently include full NFO file previews, offering detailed information about each post such as naming conventions, file structure, format type, and compression method. This is a major benefit when verifying accuracy before sending an NZB to your newsreader.
- Advanced Search Filters – Unlike other raw search engines, NZBKing includes powerful filtering tools. You can narrow searches by:
- Type
- Poster
- Newsgroup
- These options streamline your workflow and reduce irrelevant results.
- Manual NZB Creation – As with other raw tools, you select article parts manually and generate your own NZB file for import into your newsreader. This process gives you full control over what’s included in your NZB.
Benefits of NZBKing
- Large Index: With over 4,000 days of retention, NZBKing can provide NZBs for much older articles than many other indexers or raw Usenet search tools.
- Highly Customizable Searches: The advanced filters and search modifiers give users precise control over results.
- Manual Verification Tools: NFO previews help ensure you’re selecting the right NZBs, saving you from wasted time, bandwidth, and storage.
- No Account Required: Completely open and free, with no registration or subscription needed.
Drawbacks of NZBKing
- No Automation or API Support: NZBKing is a manual-only tool. There’s no support for Sonarr, Radarr, or automated NZB grabbing.
- Basic Interface: The layout is functional but not polished. It’s geared toward hand-on users rather than users with automated Usenet setups.
- No Community Features: Unlike curated indexers, there’s no forum or user interaction.
- Requires Technical Know-How: Filtering and manual NZB creation require some familiarity with how Usenet works.
NZBKing is Best When Paired with a High-Retention Usenet Provider
NZBKing’s deep archive of over 4,000 days is only as useful as your Usenet provider’s ability to access it. Many providers fall short when it comes to retrieving older articles, which can lead to incomplete NZBs or failed downloads, even if the post appears in NZBKing’s search results.
