Glific is a free, libre, open source platform. As such you can download and use the codebase for free. While the platform per se is free, it is built on the WhatsApp Business API so there is a cost involved with sending and receiving messages via WhatsApp Business API, and in running the platform on servers. The total cost of running the platform including managed server and messaging costs can be found below.
