Unlike the other tools here, this one does not work on its own. It reads from the Google Analytics Data API v1 and therefore asks for a Google sign-in. The permission requested is analytics.readonly — read-only, so nothing can be changed through it.
What it fetches stays in this tab: the evaluation runs in the browser, and nothing is sent to lukaswojcik.com. The OAuth Client ID below is prefilled and can be replaced with a different one.
Connect directly to the Google Analytics Data API v1 via OAuth 2.0 to scan the traffic dimensions (OS, Browser, Country, Source/Medium) for non-human crawler patterns, ghost spam, and zero-engagement bot segments. All heuristic evaluations execute locally in the browser — zero data is stored or transmitted to our servers.
