When to choose:
  • You want to try the Xiaozhi voice assistant on a computer without ESP32 hardware.
  • You want offline wake words with Sherpa-ONNX, echo cancellation and a GUI or command-line mode.
  • You want ready MCP tools such as schedules, timers, music, train tickets, web search and maps.
When to skip:
  • You want a self-contained assistant: AI features depend on the Xiaozhi service.
  • You cannot use Python 3.9 to 3.12, working audio devices and an internet connection.
  • You want to self-host the backend: that is the server projects' job.

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.
