Botpress is itself already open source — its core platform is available under an MIT/AGPL dual license and can be self-hosted for free, with a hosted enterprise-grade cloud offering for teams that don't want to manage infrastructure.
Since Botpress is already open, the useful comparison is between visual builders for different kinds of AI automations. Flowise AI is an open-source alternative worth comparing if you want a more general drag-and-drop builder for LLM pipelines and agents, rather than Botpress's chatbot-specific focus.
