Grams Search

is a search engine for Tor based darknet markets launched in April 2014. The service allows users to search multiple markets for products like drugs and guns from a simple search interface.

The services uses a custom API to scrape listings from several markets such as

Alpha Bay

and others, to return search listings. The site is described by the Global Drug Policy Observatory to have "transformed how people search the hidden web".

In May 2014 the site added


, a service similar to

Google's AdWords search

sponsorship system for vendors. Additionally their profile system allows for cross-market vendor contact details and reviews to be held centrally.

Later that year in June the creators released

Grams Flow

, a clearnet to Tor redirection service serving various dark net sites and in November, a banner advertising network for Tor sites, TorAds which has not yet had much success.


allows central content and identity management for vendors, reducing the complexity of around maintaining presences on multiple markets.
