- By default, the only domain that reaches our servers is one you explicitly check.
- The as-you-browse badge is off by default. Turn it on and the extension reads existing public scores for the sites you visit — it never triggers new scans.
- Page content is never transmitted, under any setting.
Chrome extension
Check any site without leaving the page.
WebTrustScore in your browser. Open the side panel, score the tab you’re on or type any domain, and get the same 0–1000 trust score this site gives — with the evidence behind it. Free, no account needed.
Chrome 116 or newer, and the Chromium browsers that share its store: Edge, Brave, Arc, Opera, and Vivaldi.
What it does
Score the tab you’re on
One click scores the site in front of you. No copying URLs into another window.
Or check any website
Type a domain into the panel and read its score before you ever visit it.
See why, not just what
Seven evidence categories, and a plain-language reason whenever a cap or a flag is holding a score down.
Your full report, in the panel
Sign in with your free account and the detailed report — every signal with its notes and evidence — opens right where you are.
What your browser sees, checked on your device
Plenty of sites block automated scanners — but your own browser sees the real page. Click “What does my browser see?” and the panel reads the page in front of you: insecure resources on an HTTPS page, where forms actually post, whether policy links exist, pressure wording, the footer identity line. It runs entirely on your device, and it is deliberately kept out of the official score — evidence collected inside a browser can be forged, so it never feeds the shared result.
What it sends, and what it never sends
Installing takes about ten seconds
Open the listing on the Chrome Web Store.
Click Add to Chrome, then confirm.
Click the icon in your toolbar — the side panel opens, ready to score.
Also from us
DomainValueScore has an extension too: a 0–1000 quality score for any domain name, in the same side panel.
