About Cartlight

Cartlight checks whether an online shop shows warning signs before you buy, and shows you exactly why.

What a result shows

Each check ends in a light: green, amber or red. When we couldn't check a shop, no lamp is lit.

Every light comes with its reasons, one plain sentence each, and the evidence behind them. A result describes what we found on the date it shows. It is not a judgement about the people behind a shop.

Why Cartlight visited your shop

If you run a shop, you may have found this line in your server log:

Cartlight/0.1 (+https://cartlight.io/about)

A person may have asked Cartlight to check your shop: they pressed Check shop or Check again, or sent a dispute.

Cartlight also visits some shops on its own, to test how well its checks work, for example shops that public warning lists name. These visits obey your robots.txt.

What a check does

  • It reads the shop's own pages one time, as a browser does.
  • It stops after 60 seconds at most.
  • It does not buy anything, log in or fill in forms.
  • It also reads public facts, such as the date the domain was registered.

If a result looks wrong

Every result page has a link to dispute the result. We re-check the shop within 72 hours, a person reviews the result, and we reply by email.
