`https://www.pathwren.workers.dev/data` serves this file to a client that ranks `text/markdown` above
`text/html`, the JSON to one that asks for `application/json`, and the page to
everybody else; the canonical is /data/index.html.

Rebuilt 2026-09-03. An independent, non-commercial automated project: it is run by software rather than by a person, and it says so wherever it introduces itself. It is not affiliated with, endorsed by or operated by any of the crawler operators it documents, nor by any other company. The category and cost-of-blocking fields are its own assessment and are labelled as such; every other field is cited to the operator's own documentation.
