Webrecorder is a hosted web archiving tool with which users can capture what they see as they browse websites and save that information. Via a web browser Webrecorder collects content and data from web pages including: HTML, images, scripts, stylesheets, Flash, Java applets as well as video, audio and other elements used to make web pages and web apps. Webrecorder can capture dynamic web content that cannot be captured by most crawler-based web archiving tools. Webrecorder can record what you see when you are logged in to a social media profile (though it does not record site login credentials).
One does not need to login to use Webrecorder to capture web content if the intent is to download the captures right away (as a WARC file) and save them locally. Desktop software that can open a WARC file, such as Webrecorder Player , is needed to view web archives downloaded from Webrecorder. Webrecorder Player is available at no charge and with this software you will be able to view all the content contained in a WARC file without being connected to the internet. For continued access to archived content online, and to be able to add to a collection, it is necessary to log in to a free account, which comes with 5 GB of storage (at least as of fall 2017).
Webrecorder is a project of Rhizome  under its digital preservation program.
