Session replay accesses the actual browsing session based on a unique identifier sent to your website as part of the URL request. It then replays this as video footage. By recording a login session, you can see exactly how a user interacts with the system and what they’re doing on your website. You’ll be able to easily rewind or fast forward sessions if you need to take an extra look.
Session replay catches everything that happens in the DOM (Document Object Model). The DOM is how users interact and experience the web. Session replay records all changes that happen in the DOM.
