Botpress

Botpress is an open-source platform for building, deploying, and managing AI chatbots and conversational agents using a visual flow builder and an LLM-agnostic architecture. It serves developers and technical teams who want to ship conversational AI across channels such as web chat, WhatsApp, and messaging apps, while a no-code studio also opens it to less technical builders. It can be used as a hosted cloud product or self-hosted for full data ownership.
