What Are Not Evil, OnionLand, and Kilos?
Google can't see a single .onion address. Here's what fills the gap instead.
Not Evil, OnionLand, and Kilos are all search engines built specifically to index and search dark web (.onion) content, something Google and other mainstream search engines cannot do. Not Evil and OnionLand function as general-purpose dark web search engines, similar in spirit to Google but scoped to Tor hidden services, while Kilos is more narrowly focused on indexing dark web marketplace listings specifically, making it closer to a specialized product search tool for that particular corner of the dark web.
Google indexes an astonishing amount of the internet, but there's one entire layer it fundamentally cannot reach: the dark web, by design, sits outside every ordinary search engine's crawl.
That gap didn't stay unfilled for long. A small handful of specialized search tools emerged specifically to index .onion sites, each with a slightly different focus and reputation. Three names come up constantly: Not Evil, OnionLand, and Kilos.
TL;DR
Quick answer
Not Evil, OnionLand, and Kilos are search engines built specifically to index dark web (.onion) content, which mainstream engines like Google cannot reach — Not Evil and OnionLand are general-purpose, while Kilos focuses narrowly on marketplace listings, and all three offer inherently incomplete coverage.
The Basics
Three answers to the same missing piece
Ordinary search engines work by crawling the visible, linked structure of the surface web, following links from page to page to build an index. Dark web sites don't participate in that structure — they're deliberately unindexed by mainstream crawlers, and many aren't linked to from the regular internet at all.
Not Evil and OnionLand both emerged to fill that gap as general dark web search engines, functioning conceptually like Google but limited entirely to .onion addresses. Users access them through Tor Browser, search a keyword, and get a list of known .onion sites matching it, though coverage is far less comprehensive or reliable than a mainstream search engine, given how much of the dark web deliberately avoids being findable at all.
Kilos took a narrower approach, focusing specifically on searching dark web marketplace listings rather than trying to index the dark web broadly. This made it, functionally, closer to a specialized product search tool for one particular slice of dark web activity, rather than a general directory.
The key distinction between the three
- Not Evil and OnionLand: general-purpose search across a broad range of .onion sites
- Kilos: narrower focus specifically on marketplace listings
- None of them achieve anywhere near the comprehensive coverage of a mainstream search engine
How dark web search engines differ from Google
Why an entirely different crawling approach is needed for .onion content.
Google's approach
Crawls a dense, interlinked surface web using standard web protocols
Onion crawling
Dark web search engines crawl known .onion links, often submitted manually
Coverage gap
Sites not linked anywhere, or deliberately hidden, simply never get indexed
A 'search engine' that can only ever see a fraction of what it's searching
Unlike Google, which aims for comprehensive coverage of the surface web, dark web search engines operate with the built-in assumption that most of what they're searching for actively doesn't want to be found — making incomplete coverage not a bug, but a fundamental, permanent limitation of the entire category.
It reframes what 'search' even means in this context — these tools aren't mapping the dark web so much as cataloguing the small portion of it that happened to leave a discoverable trail somewhere.
Misconception
Dark web search engines like these index the entire dark web, similar to how Google indexes the surface web.
Reality
Coverage is inherently partial and inconsistent. Many .onion sites are never linked to publicly, use rotating addresses, or deliberately avoid being indexed at all, meaning even the best dark web search engine only reflects a fraction of what actually exists.
How the three tools compare
Same broad category, meaningfully different scope.
| Not Evil | OnionLand | Kilos | |
|---|---|---|---|
| Primary focus | General .onion search | General .onion search and directory | Marketplace listing search specifically |
| Best suited for | Broad exploration of indexed onion sites | Directory-style browsing of categorized sites | Comparing listings across multiple marketplaces |
| Comprehensiveness | Partial, like most dark web search tools | Partial, similar limitations | Narrower scope by design, not attempting broad coverage |
The more specialized search tool ends up feeling more reliable than the general ones
You'd expect the broadest search engine to be the most useful, but within this narrow ecosystem, the more focused Kilos-style approach — deliberately narrowing scope to just one category of content — has tended to produce more consistent, relevant results than broader tools trying to cover the entire dark web at once.
If these tools can't index everything, how do they decide what to include?
Without a fully crawlable link structure like the surface web has, how does a dark web search engine actually build its index?Largely through a mix of manual submission (site operators or users adding links directly), crawling known directories and forums for new .onion addresses, and, in some cases, monitoring known link-sharing communities for freshly posted sites. It's a slower, patchier process than Google's automated web-wide crawling, which is part of why coverage stays inherently incomplete no matter how long any of these tools have been operating.
Researchers using these tools for tracking, not shopping
Cybersecurity researchers and academic teams studying dark web marketplace trends have documented using tools like Kilos specifically to track pricing and listing patterns across multiple marketplaces at once, for research and threat-intelligence purposes rather than personal use.
Tools built for one audience often end up serving a very different one — in this case, researchers studying the ecosystem from the outside, using the same search infrastructure built for participants inside it.
A few practical realities about using these tools
Search results can include scam or malicious sites
These search engines don't verify the legitimacy or safety of what they index, unlike mainstream search engines' spam-filtering systems.
Coverage changes constantly as sites go up and down
Dark web sites are far less stable in uptime and address than ordinary websites, so results can quickly become outdated.
None of these tools verify legality of what's listed
Indexing a site doesn't imply endorsement or vetting of its content or legality in any way.
Are dark web search engines a reliable equivalent to Google?
No — they serve a genuinely useful, narrow function, but reliability and comprehensiveness fall well short of mainstream search engines by necessity.
The dark web's design deliberately resists comprehensive indexing, meaning even the best specialized search tools only ever surface a partial, frequently changing slice of what actually exists.
What this says about search as a reflection of what wants to be found
Google's dominance rests on an assumption most of us never think about: that most of the internet wants to be discovered. Dark web search engines operate under the opposite assumption, and their permanent, structural incompleteness is a useful reminder that 'search' was never really a neutral technology — it's always been shaped by how much of what it's searching actually consents to being found.

A map that can only ever be partly drawn
Not Evil, OnionLand, and Kilos aren't lesser versions of Google — they're honest attempts at mapping a territory that was built, on purpose, to resist ever being fully mapped at all.
