Ahmia

Ahmia is a clearnet search engine for Tor's hidden services created by Juha Nurmi.

Overview
Developed during the 2014 Google Summer of Code with support from the Tor Project, the open source search engine was initially built in Django and PostgreSQL. It indexes .onion URLs from the Tor network, excluding those containing a robots.txt file. The search engine also filters out child pornography and keeps a blacklist of abusive services.

The service partners with GlobaLeaks's submissions and Tor2web statistics for hidden service discovery and as of July 2015 has indexed about 5000 sites. Ahmia is also affiliated with Hermes Center for Transparency and Digital Rights, an organization that promotes transparency and freedom-enabling technologies.

In July 2015 the site published a list of hundreds of fraudulent clones of web pages (including such sites as DuckDuckGo, as well a dark web page). According to Nurmi, "someone runs a fake site on a similar address to the original one and tries to fool people with that" with the intent of scamming people (e.g. gathering bitcoin money by spoofing bitcoin addresses).
