Finding working onion links can be difficult. Like the clear net you can use search engines to find exactly what you are looking for. Below is a list of the best search engines for finding cool and useful onion links.
Torch or Tor search is the dark net’s first search engine. They claim to have over 1 million onion websites indexed and auto update their index daily. The only issue I found with Torch is they don’t give good search results and lots of dead links. They also have a clear net search engine torsearch.net
Having been established in 1996, this is one of the oldest darknet search engines in existence (possibly the oldest!), and they’re still kicking. They display ads on their website, but they are not personalized based on user data in any way.
TorDex or Tor Index is the largest search engine on the dark net. They seem to only have 500,000 onion sites indexed but most of them work and give good results. The issue with TorDex is their index is full of junk websites that lead to CP!!!
Like Torch, TorDex also displays ads on the site to generate revenue. Again, these ads are not personalized using tracking cookies or other personal data.
Ahmia is a clear net search engine research project. They censor their search results, but that may be a good thing depending on your opinion.
Unlike most darknet search engines, Ahmia is actually completely open source! Anyone can view the code and see the algorithms that are returning the results. Also, anyone can self-host the software for themselves and run their own version of the engine, adding or removing blacklists as they see fit.
It also contains some advanced features that researches or simply curious individuals may finding interesting, such as a link graph that displays which onions link to which other onions.
They also have an I2P engine for searching I2P instead of Tor.
HayStak is a simple tor search engine with a nice design and logo. The only issue with it is they seem to “503” error a lot because their server is over loaded.
Like some other search engines, they disallow extreme content such as CP and human trafficking.
They offer a premium service that allows you to search for onions that are no longer online, search using regexes, use machine learning to tailor search results even further, access their database of bitcoin address, email addresses, and visa card numbers, receive emails when new content gets indexed that matches a term, and access their API to use their search engine for your own projects.
Onion Land is another Tor search engine with a large index and good search results. They also have the sites cached if the onion goes down, so you can still see what the website looked like.
Onion Land, like several other search engines, displays many ads on their homepage and their results page. Once again, these ads are static and are not personalized in any way.
They also provide a list of search terms that are the most popular and frequently queried by users, as well as a link to go to a random onion site (be careful with this one!).
Tor66 is a cool project that allows you to search for onions only and not their sub pages. They have a really good search algorithm and screenshots the websites. They have a very large index of onions and add 100’s everyday.
They display non-personalized ads on their site. They also offer a list of the most popular onion sites, as per their calculations.
