how it works

Turn on Headlamp. Test your app.
Discover what you've missed.



Launch Chrome and browse to your web app.



Open Headlamp from the Chrome extensions menu and hit the Start button. Headlamp puts red dots next to all the links, input elements, and buttons.



When you click, type, or change something, the corresponding red dot disappears.

Testing iterations gets challenging when there's little or no documentation about new features. Headlamp helps Agile teams by shining a bright light on every additional testable element as soon as it shows up in the build.


Got a tight deadline? Headlamp's TEAM edition lets you collaborate with your entire test team and quickly cover the entire app.

Headlamp lights the way to untested parts of your app so everyone can lend a helping hand.
