Botpress

Botpress is the complete, open-source conversational AI platform for building, deploying, and managing powerful, LLM-powered AI agents (chatbots and voice assistants).

Botpress is the all-in-one AI agent platform, designed for rapid deployment across multiple channels (web, WhatsApp, Slack, etc.). The visual, drag-and-drop Botpress Studio allows non-developers to build complex conversational flows quickly. It leverages modern LLMs and a custom inference engine (LLMz) to deliver contextual, stateful conversations. Agents integrate with existing business systems via APIs, and the platform uses knowledge bases to train bots on specific data (documents, websites) for accurate, on-brand answers. The core value: speed, control, and open-source flexibility for enterprise-grade conversational AI.
