In this post I will explained how to find the site
template using client side/browser.
Step 1. Browse to any page on the site and view the
HTML source code of the page then search for the "SiteTemplateID" in
the javascript embedded into the page such as
var g_wsaSiteTemplateId = 'STS#0';
Step 2. Check the g_wsaSiteTemplateId value in
the site template available in SharePoint 2010 by default from below link
Above siteTemplateId indicate teamsite.
