EPAdb is a free and ready to use project, but registered users can get many benefits:
Although our business model is similar to that of a non-profit institution, we have, like any other company, costs associated with the services we provide. So, to cover these expenses we rely on subscriptions and advertising. However, the companies that advertise on EPAdb do not have any interference in our editorial criteria.
As a work in progress we are constantly thinking about new features to improve our service, so feel free to send us your suggestions.
