OpenSincera Visualizer

See OpenSincera's publisher metrics for any site you visit, in one click. Click the toolbar icon and a panel slides in with that site's OpenSincera data: how much of the page is ads, how often ads refresh, how heavy the page is, which supply paths and ad tech it uses, and more. Nothing loads until you click, and the panel closes with Esc. WHAT YOU'LL SEE • Overview: ads-to-content ratio, ads in view, ad refresh rate, page weight and CPU use. For web publishers, key metrics are drawn against OpenSincera's optimal range so you can see at a glance whether a site falls within, above or below it. • Device: mobile vs. desktop side by side, including ads-to-content, ads in view and refresh. • Supply: supply paths, resellers, unique GPIDs, ID absorption rate, owner domain, and publisher and parent IDs. • Tech: detected ad servers, header-bidding wrappers, identity providers, encrypted signals, analytics, video players and more. • Similar: publishers OpenSincera considers similar in content, compared side by side with the current site and linked to their OpenSincera pages. • Page: metrics for the exact page you're on (if OpenSincera has sampled it), overlapping-ad warnings, and the site's top sampled pages. Subdomains that OpenSincera doesn't track fall back to their parent domain (for example, edition.cnn.com shows cnn.com), and the panel tells you when that happens. Every view links to the publisher's full profile on OpenSincera. BUILT TO RESPECT YOUR API QUOTA • Requests are made only when you click the icon, never on page load. • The Page and Similar tabs load only when you open them. • Results are cached for 6 hours per site. A refresh button fetches fresh data whenever you want it. • Clear messages for untracked sites, invalid tokens and rate limits. GETTING STARTED 1. Create an OpenSincera account at open.sincera.io and copy your API token. 2. Open the extension's settings, paste the token and save. It's checked straight away. 3. Visit any site and click the OpenSincera icon. PRIVACY Your API token is stored only in your browser. The extension sends the site's domain to OpenSincera's API, and nothing else: no full page URLs, no browsing history, no analytics or tracking. Data is shown exactly as OpenSincera reports it. Light and dark mode follow your system setting. Data from OpenSincera by The Trade Desk.
