Competitor research: on-site marketing tags and running ads from public ad libraries for any domain. Superpixel is a free, open-source competitor research tool that lives in Chrome's side panel. Type a domain or scan the tab you are on, and it answers two questions: what is installed on the site, and what is the company advertising right now. ON-SITE TAGS See the marketing, advertising and analytics tags installed on a website, together with the account IDs behind them. Tags loaded through a tag manager container are detected as well. RUNNING ADS Superpixel searches the public ad transparency libraries that the major ad platforms publish and shows the ads and advertisers that point to the scanned domain. Results stream into the panel as each library answers. Every ad carries a label that shows how sure Superpixel is that it belongs to the scanned domain. HONEST STATUSES When a library limits requests or changes its format, its card says so instead of quietly showing no results. Libraries that cannot be searched automatically get a direct link instead. EXPORT Download the full result of a scan as a JSON file. PRIVACY Everything runs in your own browser. There is no account, no tracking and no personal data collection. An optional debug log, off unless you turn it on, helps fix broken library integrations.
