Docs Config Fallback

Fallback

Tries to use whichever node comes first in your list; once the current node times out, it automatically falls back to the next healthy node in order.

Example Config

config.yaml YAML

proxy-groups:
  - name: "fallback"
    type: fallback
    proxies:
      - ss
      - vmess
    url: 'https://www.gstatic.com/generate_204'
    interval: 300
    # lazy: true

The difference from url-test: url-test picks "whichever is fastest right now," while fallback "prefers whichever is listed first, only moving on once it fails" — a good fit if you have a clear priority preference for a specific route.

See common fields for the rest.
