Geosite.dat Inspector

Import a database

Select a local Geosite.dat file and click Parse file. You can also load the synthetic example first. Failed replacements retain the parsed database. Clearing, changing language or account, or leaving the page clears the workspace.

Browse and query

Categories and entries retain their original positions; duplicate codes are never merged. Search category codes or attribute keys, then open a category to search entry values, types and attributes, with 25 entries per page. Enter an ASCII or Punycode domain and check literal matches, indeterminate categories and non-matches. Attributes are displayed as metadata only.

Interpret the results

Root rules check label boundaries, full rules check exact domains, and keyword rules check literal substrings. Queries are lowercased and one trailing dot is removed. Regex, unknown types or matching fields, and unsupported literals remain indeterminate and never execute. A known match provides local evidence; a non-match does not rule out unchecked conditions. This is not client routing, DNS, connectivity or full validity verification.

Limits and privacy

Limits are 16 MiB, 4096 categories, 250000 entries, 500000 attributes and 64 attributes per entry. Complete reports are limited to 2 Mi characters. Strict UTF-8, structure and text budgets reject invalid files atomically, including duplicate singular fields. Unknown fields retain counts only. Resource hashes, codes and file paths are omitted and never fetched. Copied reports contain category codes, domains and visible attributes; review them before sharing.
