ThriftDB is currently in private beta. While the service is in beta it will be free for all users.
Like most cloud services, we will eventually charge users based on resources used. Right now our goal is to improve the service and build an understanding of our users' requirements before choosing a pricing model. We would like everyone to have access to our search technology so we will always strive to make ThriftDB as affordable as possible.
If you would like to use ThriftDB for your website or application, you can sign up for our beta program by clicking here.
