Chrome has emerged as one the most popular and widely used browsers in the world. But few people are aware of the cool experimental features that are hidden in this browser. The best part is that anyone can try their hand on these features, and tweak the browser to suit their preferences.

What are Chrome Flags?

Chrome flags are developmental and prototype features hidden in the Chrome browser. These features are not yet released to the public, but if you like to play around with the browser and its features, this is right up your alley.

Chrome flags have a long list of features, some useful and some not so much. These features are so cutting-edge that they might not even work for everybody. We’ve noticed that sometimes different computers gave out different results for the same flag. If you use them well, they can enhance your browsing experience significantly.

Since these features still in their nascent experimental stage, they are prone to disappear altogether or reappear in a different avatar. In short, keep checking back for newer features.

How do I open Chrome flags?

It is very simple.

To enable Google Chrome Flags, type in chrome://flags/ in the address bar of your Chrome browser.

Alternately, you can type in chrome://chrome-urls/ for a list of all Chrome URLs and click on Flags.

This will throw up a whole list of really cool experiments that you can add to your browser and improve your browsing experience. Enabling some of the best Chrome Flags can make your browsing experience completely different from the default browsing mode.


Remember, these are still experimental features, so don’t be disappointed if some of them don’t work for you. Chrome also warns that some of these experiments could compromise your security and privacy; they could also wipe out all your data.

With a warning right up front, Chrome warns users to take caution while having fun with these features.


If your browser starts acting up after enabling certain flags, remember that you can disable it by clicking on the reset button. Whenever you enable an experiment, you will need to reload the browser for it to take effect.

If you are feeling particularly adventurous or bored with using the same old run-of-the-mill Chrome and feel that you need something more adventurous, read on. We have listed some of the coolest Chrome Flags for you.
