Botpress

Botpress is an open-source conversational AI platform that allows developers to build, deploy, and manage chatbots with full control over customization and data privacy. It supports natural language understanding (NLU), multi-channel deployment (web, Slack, Facebook Messenger), and integration with external APIs.

Its unique advantage is being open-source, offering flexibility and ownership without vendor lock-in.
