Is AddThis free?

Yep! The features you see today on AddThis will always be free.

Do I need to create an account?

No. You only need to create an account if you want to see how your users are sharing your blog; the sharing itself works the same either way.

Is JavaScript required?

If you've turned on the drop-down menu (which is recommended, as it's been shown to increase sharing/bookmarking rates), JavaScript must be enabled. We load the actual interface via JavaScript at run-time, which allows us to upgrade the core functionality of the menu itself automatically everywhere.
