Quick Definition: A Usenet indexer is a searchable database of NZB files posted to Usenet newsgroups. Instead of browsing raw binary files through a newsreader, you search the indexer, grab an NZB file, and feed it to a download client. DrunkenSlug and NZBGeek are two of the most respected member-based indexers in the space, and choosing between them comes down to access model, retention depth, and how you run your setup.
If you are building a serious archive of older, obscure binary files, the indexer you pick will either make or break your searches. DrunkenSlug and NZBGeek both sit near the top of the community’s recommended list, but they serve slightly different users in practice. One leans harder into rare and hard-to-find content; the other is more accessible and consistent for day-to-day use.
This guide breaks down both indexers across the factors that matter most for archival work: retention depth, API behavior, pricing tiers, and how well each one surfaces content that does not show up anywhere else. We also cover the best backup indexers and explain why your choice of Usenet provider matters just as much as your indexer.
What Matters Most For Archival Searches
For archival Usenet searches, raw index size is less important than how well an indexer tracks older binaries, filters out incomplete posts, and relies on community effort to surface obscure finds.
Why Retention Matters More Than Raw Index Size
Retention refers to how far back an indexer’s NZB index reaches. A large index filled with recent posts does not help if you are hunting for a binary file posted three or four years ago.
High retention means the indexer has continuously crawled and catalogued Usenet newsgroups over a long period, preserving NZB files even after the original posts age off many servers. For archival users, this is the single most important metric to evaluate.
Both DrunkenSlug and NZBGeek have solid retention signals, but community reports consistently position DrunkenSlug as the stronger pick for older and more obscure uploads.
How Community Curation Affects Obscure Finds
Automated crawlers index what they can see. Community curation fills in the gaps. Indexers with active, engaged user bases tend to catch re-posts, niche releases, and manually submitted NZB files that automated systems miss.
NZBGeek has a well-established community and has been operating long enough to accumulate a broad catalogue. DrunkenSlug’s invite-only model keeps its user base smaller but more focused, which in practice means less spam and fewer fake or incomplete uploads polluting the search results.
For obscure binary archives, a cleaner index often produces better results than a larger but noisier one.
When A Search Engine Beats A Forum-Style NZB Index
Some content surfaces more easily through a direct Usenet search engine like Binsearch than through a curated indexer. Raw search tools query headers directly, which can uncover posts that no indexer has catalogued yet.
The trade-off is usability. A search engine returns raw results without completion checks or NZB packaging. For archival hunting, the best workflow combines a curated indexer as the primary tool with a raw search engine as a fallback.
DrunkenSlug Vs NZBGeek At A Glance
The two indexers differ most on how you get in, how far back their data reaches, and how consistently they stay available during daily use.
| Feature | DrunkenSlug | NZBGeek |
|---|---|---|
| Registration Model | Invite-only | Open registration |
| Free Tier | 5 NZBs, 100 API hits/day | 3-day trial, 15 NZBs total |
| API Access | Yes, tiered | Yes, unlimited on paid plans |
| Best Known For | Rare and older content | Broad, consistent coverage |
| Community Style | Private, focused | Larger, more open |
Registration Friction: Invite-Only Vs Open Access
Getting into DrunkenSlug requires an invite from an existing member. Registrations do open occasionally, but the windows are short and unpredictable. This is the biggest practical barrier for new users.
NZBGeek uses open registration, which makes it the easier starting point for anyone new to Usenet indexers. For most beginners, NZBGeek is the first paid indexer they join precisely because of this accessibility.
If you already have a Usenet community connection, securing a DrunkenSlug invite is worth the effort. If you are starting fresh, NZBGeek is the more realistic entry point.
Retention Signals And Historical Depth
DrunkenSlug is consistently praised in community discussions for surfacing older and rarer uploads that NZBGeek does not index. Its false-negative rate on NZB verification is notably lower, meaning you are less likely to download an NZB that turns out to be broken or incomplete. Its retention pool exceeds 3,000 days across every membership tier, including the free one.
NZBGeek’s historical depth is solid for mainstream and recent content. It covers a broad range of newsgroups and categories, and its database has been growing for years.
For archival hoarders specifically, DrunkenSlug’s edge in obscure content coverage is real and worth the invite barrier.
Uptime, Reliability, And Day-To-Day Consistency
NZBGeek has a strong reputation for uptime and reliable API responses. Users running API synchronization hubs with multiple trackers report fewer outages and more consistent search results compared to smaller indexers.
DrunkenSlug is generally reliable but has experienced periods of downtime. For automation-heavy setups where a missed search window means a missed archive, NZBGeek’s consistency is a meaningful advantage.
Running both in parallel is the approach most serious hoarders take, using DrunkenSlug for the obscure finds and NZBGeek for reliable day-to-day coverage.
API Limits, Automation, And Workflow Fit
API behavior determines how well each indexer slots into an automated archival setup. Both support the Newznab standard, but their limits and reliability differ in ways that affect practical workflow design.
API Key Setup And Newznab Compatibility
Both DrunkenSlug and NZBGeek use the Newznab API protocol, which means setup in any compatible client is straightforward. You generate an API key from your account settings, paste it into your client, and the indexer appears as a search source immediately.
The Newznab standard means both indexers work with the same integration flow. No custom configuration is required beyond the server URL and API key.
How Each Indexer Fits Sonarr, Radarr, And Lidarr
NZBGeek’s unlimited API hits on paid plans make it well-suited for API synchronization hubs running multiple archival data organizers simultaneously. Sonarr, Radarr, and Lidarr can query NZBGeek frequently without hitting a ceiling.
DrunkenSlug applies API hit limits depending on your tier. For users running large automated libraries, hitting those limits during active search cycles is a real possibility. Paid tiers raise the ceiling, but NZBGeek’s unlimited model is more forgiving for high-frequency automation.
For lossless audio archiving specifically, community reports note that DrunkenSlug often surfaces releases that NZBGeek’s automation misses entirely.
SABnzbd And NZBGet Integration Differences
Both SABnzbd and NZBGet accept NZB files from either indexer through standard Newznab integration. DrunkenSlug also supports a cart-based download workflow, where you queue NZBs in the indexer’s interface and SABnzbd picks them up automatically without requiring direct API configuration.
This cart method is useful for users who prefer manual curation over full automation. It reduces API hit consumption and gives more control over what actually enters the download queue.
NZBGet users will find NZBGeek’s direct API integration slightly more streamlined for fully automated setups.
Pricing, Access Tiers, And Overall Value
Cost is a meaningful factor when running multiple NZB sites alongside a Usenet provider subscription. Both indexers offer free tiers, but the limits shape how usable they are in practice.
Free Tier Trade-Offs For Light Users
DrunkenSlug’s free tier allows 5 NZB downloads and 100 API hits per day, with access to the same 3,000+ day retention pool as every paid tier. For light, manual archival searches, this is functional. For automation, it runs out quickly.
NZBGeek’s free trial is far more limited: three days of access capped at 15 total NZB downloads, meant only for evaluating the interface rather than sustained use.
For someone just exploring Usenet indexers, DrunkenSlug’s free tier offers slightly more usable daily access, assuming you can get an invite.
When VIP Pricing Makes Sense
DrunkenSlug’s paid tiers scale from Lager (25 NZBs, 250 API hits/day, roughly €5/year) to Ale (100 NZBs, 1,000 API hits/day, roughly €10/year) to Wine (200 NZBs, 2,000 API hits/day, roughly €20/year). NZBGeek’s VIG membership removes download caps entirely and unlocks full API access, available as an annual subscription or a one-time lifetime purchase.
VIP pricing makes sense once you are running automated archival data organizers against the indexer daily. The API ceiling on free and entry tiers will throttle automation before you exhaust your actual search needs.
NZBGeek is frequently cited as offering strong value at its paid tier, particularly given the unlimited API access.
Cost Of Running Multiple NZB Sites
Most experienced archival hoarders run two or three indexers simultaneously to maximize coverage. The combined cost of two paid indexer subscriptions plus a Usenet provider is still reasonable for anyone serious about digital preservation.
The practical approach is to treat NZBGeek as the reliable primary and DrunkenSlug as the specialist secondary. That combination covers both consistent daily coverage and the obscure finds that require deeper indexing.
Alternatives And Backup Indexer Strategies
No single indexer covers everything. A layered strategy using alternatives and backup search tools fills the gaps that DrunkenSlug and NZBGeek both leave.
Where NZBFinder Fits As An Open Alternative
NZBFinder is one of the most recommended open-registration alternatives to both DrunkenSlug and NZBGeek. Its free tier offers 5 NZB downloads and 5 API hits daily, which is enough to evaluate it before committing to a paid plan.
NZBFinder’s API limits on entry tiers are higher than DrunkenSlug’s, making it more automation-friendly for users who cannot get a DrunkenSlug invite. It works cleanly with Sonarr, Radarr, Lidarr, SABnzbd, and NZBGet through standard Newznab integration.
When NZBPlanet Or DogNZB Make Sense
NZBPlanet offers broad coverage and is frequently recommended alongside NZBGeek for users who want overlapping databases without paying for a private invite-only indexer.
DogNZB is a solid choice when you want a community-focused indexer with decent retention for less mainstream content. It does not match DrunkenSlug’s depth for truly obscure archives, but it adds meaningful redundancy to a multi-indexer setup.
For archival hoarders running three indexers, a common configuration is NZBGeek plus DrunkenSlug plus either NZBFinder or NZBPlanet as a third source.
Using Binsearch Or UsenetCrawler As Backup Search Tools
Binsearch is a free public Usenet search engine that queries headers directly. It is rudimentary and lacks NZB quality filtering, but it reaches content that no curated indexer has catalogued. For truly obscure binary files, it is a useful last resort.
UsenetCrawler and NZB.su provide additional fallback search coverage. Neither replaces a quality curated indexer, but both are worth bookmarking for the occasional search that comes up empty everywhere else.
Choosing The Right Setup For Your Use Case
The best indexer configuration depends on whether your workflow is manual, automated, or a hybrid of both. Either way, the indexer is only as useful as the Usenet provider behind it.
Best Fit For Manual NZB Search
For manual archival searches where you browse, evaluate, and selectively download, DrunkenSlug’s interface and cleaner index make it the more satisfying experience. The lower false-negative rate means fewer wasted downloads.
NZBGeek also works well for manual search and has a more straightforward registration path. For users who are new to indexers and not yet running automation, NZBGeek is the easier starting point.
Best Fit For API Synchronization Hubs
NZBGeek’s unlimited API hits on paid plans make it the stronger choice for users running fully automated archival data organizers. High-frequency querying from Sonarr, Radarr, or Lidarr will not be throttled.
DrunkenSlug can run in automation alongside NZBGeek as a secondary indexer. Because it surfaces content the others miss, adding it to your Prowlarr or direct Newznab configuration expands coverage without replacing NZBGeek’s reliability.
Why Your Indexer Still Needs A Strong Provider
An NZB file is only the map. The actual binary data lives on the Usenet provider’s servers, and if the provider has weak retention or incomplete binaries, even the best indexer cannot help.
No matter which indexer combination you settle on, pairing it with a high-retention provider is the step that actually determines whether your archival downloads complete successfully.
For that reason, most archival hoarders pair their indexer with a provider built for retention and completion rather than the cheapest plan available. Get Newshosting for unlimited access with strong retention across newsgroups, or Get Easynews if you also want built-in web search and preview alongside your NZB workflow.
