From licence key to a running agent
Rasa is a commercial platform with a free Developer Edition for individual builders. Request a licence key, install rasa-pro, and create a Mantle agent. Write skills as plain-language instructions and add checks for actions that need tighter control.
Already have a licence? The quickstart takes you through one complete local agent.
