Bookmarklet

Our bookmarklet provides a convenient way to see the technologies of the sites you visit.

Then click on it whenever you visit a site whose technologies you want to know. If the concept of bookmarklets is new to you, you may read more about it on Wikipedia.

Browser Extensions

Our browser extensions work similar to the bookmarklet, but they use browser capabilities to show the current site's web technologies, so that your site visits are not interrupted.
