When to choose:
  • You own xiaozhi-esp32 hardware and want to host your own backend instead of a shared one.
  • You want MQTT+UDP or WebSocket, MCP endpoints, voiceprint recognition and a knowledge base.
  • You want a choice between a minimal no-database install and a full install with a web console and multi-user management.
When to skip:
  • You have no ESP32 device: it is not useful without compatible hardware.
  • You need production use: the README says it is incomplete and has not passed a network security evaluation.
  • You cannot work from mainly Chinese documentation.
