It helps coffee drinkers explore new beans, compare options and buy directly from the people who roast them. The site lists coffees from 44 roasters, with details such as origin, size, price and availability, and offers filters for brewing style, roast level, flavour profile, decaffeination and budget.

Visitors can browse beans by country of origin, explore featured coffees and meet roasters including Bocca Coffee, Rum Baba Coffee Roasters and Coffee & Coconuts. roazon also tracks changes across roaster websites, highlighting new listings, restocks and price drops, with options to watch coffees and receive email alerts. Its updates are refreshed every weekday, making it easier to keep up with changing selections.

The catalog focuses on coffee beans rather than brewing equipment, machines or merchandise. For roasters not yet listed, users can request that roazon fetch and add their coffee shelf.
