Free GEO scanner: 40 published checks, no account, no email.

LLMention is a free GEO scanner. It fetches a homepage the way a crawler would and scores it against 40 published checks across 12 weighted dimensions, then reports every failure with the evidence that produced it. Every rule, its point value and the condition that makes it pass are published, along with what each check does not test. No account, no email, and no AI engine is ever queried: it measures whether a page can be read, extracted and cited, not whether any engine currently mentions you. The source is MIT-licensed, and a study over 30 homepages - none scoring an A - is downloadable and reproducible from the public API.
