Sing-box Route Inspector

Notes

• Paste a sing-box JSON config and the page will inspect route.rules, route.rule_set, outbounds, inbounds, dns, and related routing fields.
• After you enter a URL, hostname, or IP, the page statically traces:
  • which route.rules entry matches first
  • whether a rule_set branch was involved
  • which outbound, selector, or urltest becomes the target
  • whether the result can be resolved all the way down to a concrete exit
  • whether TUN is enabled and how DNS is configured
• The page supports inline rule sets and remote + format: source rule sets.
• When the config still uses the legacy geosite field, or when a source rule set contains geosite branches, the page also attempts to load the official geosite.dat and includes the matched category and domain rule in the explanation.
• The result is also rendered as a flow graph so you can screenshot it or explain the path to someone else.
• Binary .srs, local file paths, and sing-box-specific GEO databases are still flagged as unsupported.
