The 10 Best Deep Search Engines to Explore the Invisible Web

Best Deep Search Engines to Explore the Invisible Web

Google and Bing are not capable of searching for everything. These extremely deep search engines are required to explore the invisible web.

There are many areas on the internet that Google and Bing’s web crawlers are unable to access, thus not everything on the internet will appear in a list of search results.

You’ll need to use specialized search engines to explore the invisible web. Here are our top 12 search engines for conducting a comprehensive online search.

What is the Invisible Web, and How Does It Work?

Before we get started, let’s clarify what the term “invisible web” means. Simply said, it’s a phrase for internet information that doesn’t show up in search results or web directories.

Although there is no official evidence, most experts agree that the invisible web is several times larger than the visible web. The numbers rapidly become mind-boggling when you consider that Google, Amazon, Microsoft, and Facebook alone store almost 1,200 petabytes.

The deep web and the dark web are two categories of material on the invisible web.

The Internet’s Deep Layer

The deep web is made up of content that requires some type of authentication in order to access. Library databases, email inboxes, personal records (financial, academic, health, and legal), cloud storage drives, workplace intranets, and so on are examples.

You can access the information using a conventional web browser if you have the necessary credentials.

The Internet’s Dark Side

The deep web is divided into two sections: the dark web and the deep web. To see the information, you’ll need a dedicated dark web browser (such as Tor). Because it is more anonymous than the ordinary web, it is frequently used for criminal operations including drug and weapon sales.

The Best Deep Web Search Engines

1. Pipl

Pipl describes itself as the largest people search engine in the world. Pipl, unlike Google, can search searchable databases, member directories, court records, and other deep internet search information to provide you with a full portrait of a person.

2. DuckDuckGo

DuckDuckGo is the Internet privacy company for everyone who’s had enough of hidden online tracking. DuckDuckGo is also well-known for being a private search engine for the visible web, but did you know it also has an onion site where you can browse the dark web?

Google isn’t the only search engine that has deeper web material. It finds its results by combining the results of more than 500 independent search tools. You may do a full online search using the standard DuckDuckGo engine and the .onion version.

The onion site can be found at http://3g2upl4pq6kufc4m.onion/.

3. The WWW Virtual Library

The WWW Virtual Library is the internet’s earliest catalog. It was founded in 1991 by Tim Berners-Lee, the inventor of the World Wide Web.

Volunteers manually build the link list, resulting in a high-quality index of deep web information in dozens of areas.

4. The Wayback Machine

The Wayback Machine is a digital archive of the World Wide Web. It was founded by the Internet Archive, a nonprofit library based in San Francisco, California.

Regular search engines only provide results from the most up-to-date version of a website. The Wayback Machine, on the other hand, is unique. Its servers save copies of over 361 billion web pages, letting you to search for content that is no longer viewable on the internet.


The amount of information available on is astounding. It’s a one-stop-shop for all the public information you’ll ever need about any federal agency, as well as state, local, and tribal governments.

You can also learn about government jobs, loans, grants, taxes, and more. The majority of the content on the site will not be found on Google.

  1. not Evil Dark Web

Check out not Evil Dark Web if you’re seeking a dark web search engine. Because the site uses the.onion domain name, it cannot be accessed using a conventional web browser. Open a dark web browser like Tor and type hss3uro2hsxfogfq.onion into the address bar to load it.

It has access to a database of over 32 million dark websites, implying that if it exists, this search engine will most likely discover it.

7. Directory of Open Access Journals

The Directory of Open Access Journals is a deep internet search engine that indexes academic articles and provides access to them. The papers are free to anyone who wants them.

There are about 10,000 journals in the archive now, with 2.5 million articles covering a wide range of topics. Some of the information is accessible through Google Scholar, but we believe the DOAJ is a better research tool.

8. Wolfram Alpha

With Wolfram Alpha you get a computational web search engine, in other words, you can enjoy a deep web search engine that has a significant amount of data for you to take advantage of. The site has categories such as:

  • Mathematics
  • Step-by-step solutions
  • Words % Linguistics
  • Units and Measure
  • Chemistry
  • Date & Times
  • Art & Design
  • Music
  • Astronomy
  • Engineering
  • Food & Nutrition
  • Shopping
  • Earth Sciences and more!

Once you choose a topic, the site gives you so many options that you won´t know where to start. For example, let us say you choose Chemistry. In that category, you can either have the site give you chemical formulas, Chemical quantities, chemical solutions, functional groups, and the list keeps going.

  1. Voice of the Shuttle

Voice of the Shuttle is a must-read for anyone interested in the humanities. Since its launch in 1994, the site has amassed one of the most amazing collections of vetted deep web content.

Over 70 pages of annotated links span topics ranging from architecture to philosophy.

  1. Ahmia

Ahmia is the search engine for .onion domains on the Tor anonymity network. It is led by Juha Nurmi and is based in Finland. But there’s a catch: it’s one of the few dark web search engines that’s also accessible on the public internet.

Of course, you won’t be able to open any of the links or results unless you have the Tor browser installed on your computer. It is, however, a terrific way to get a taste of what is accessible on the dark web without exposing yourself to the risks that come with accessing it.

There are more Search engines available except these to Search the Invisible Web.
