If CorbaCount turned up in your server logs, this page explains exactly what it is, why it visited, and how to recognise it. Short version: someone runs CorbaCount web analytics on a site, and we made a small, well-behaved automated request on their behalf.
Mozilla/5.0 (compatible; CorbacountScreenshotBot/1.0; +https://www.corbacount.com/bot)
CorbaCount is a privacy-friendly analytics tool. When a customer adds a website to their account, we make a few automated requests to that domain so their dashboard has a preview image and up-to-date domain-health data. These requests are infrequent, identify themselves honestly, and never crawl or index your pages.
Shows up in your access log
A headless Chromium browser loads the site's homepage to capture a thumbnail for the customer's dashboard.
CorbacountScreenshotBotDoes not show up in your access log
Powers the domain health panel: we read the site's public SSL certificate to warn the customer before it expires.
A few requests a month per site. No bursts, no crawling, no repeated hammering.
The screenshot bot loads the homepage once, usually within a minute or two.
The certificate check reads the SSL certificate with a TLS handshake.
The screenshot bot refreshes the thumbnail with one more homepage load.
All requests stop. Nothing is kept polling in the background.
Every HTTP request we make to your site carries this user-agent, pointing back to this page. If you see a different user-agent claiming to be CorbaCount, it is not us.
Requests to your website
Mozilla/5.0 (compatible; CorbacountScreenshotBot/1.0; +https://www.corbacount.com/bot)
Requests to public registries and data providers, never to your website
CorbaCount/1.0 (+https://www.corbacount.com/bot)
It does not spider your links, scrape your content or build a search index. The screenshot bot loads a single page.
About two homepage loads a month, plus a weekly TLS handshake. Nothing a server would notice.
These requests are about the site itself. Visitor analytics only ever come from the tracking snippet a customer installs.
We never spoof a real browser to hide the request. The user-agent always says CorbaCount and links straight back here.
Almost always it means someone with access to the site - an agency, a developer, a colleague - added it to a CorbaCount account to measure its traffic. If that is unexpected, check with whoever manages the site.
If you would like us to stop, or you believe the site was added without authorisation, tell us through the contact page and we will remove it.
Yes. The screenshot bot sends a stable, identifiable user-agent, so you can return a 403 for anything matching corbacount. Blocking it simply means the customer's dashboard shows a placeholder image instead of a preview of your site.
# nginx, inside the server block
if ($http_user_agent ~* "corbacount") {
return 403;
}
# Apache (.htaccess)
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} corbacount [NC]
RewriteRule .* - [F,L]
Send us the log line - the user-agent, the IP and the timestamp - and a real human will tell you exactly what it was, within one business day.
