About unpkg
unpkg is a free, community-run content delivery network that serves any package published to the npm registry.
A site loads a JavaScript library directly from unpkg.com instead of hosting a copy itself, which reveals the request to unpkg's servers but sets no cookies. It isn't counted as a tracker here since delivering the file is the whole job.
Often loaded alongside
Sites that load unpkg most often also load Google Analytics (80%), Google (70%), Google Ads (60%), OneTrust (33%), and jsDelivr (32%).

Understanding this page
- What the tracker categories mean
What "advertising," "analytics," "social," "consent" and the rest actually mean for a company or a cookie, and how CookieTosser decides which one applies.
- First-party vs third-party cookies (and why "first-party" still tracks you)
What the distinction actually means technically, why browsers only block one of the two, and how CNAME cloaking, server-side tagging and cookies like _ga let sites keep tracking under their own domain.
- How to block or limit trackers
Browser privacy settings, content blockers, Global Privacy Control and clearing cookies compared honestly — what each one actually stops, what it doesn't, and what it costs you in return.
