What is the difference between Sessions and Replay Sessions?
Applies To
- All SaaS Customers
Resolution
Sessions
The primary component Sentry uses to monitor health is a session, which represents the interaction between the user and the application.
You can find more detailed information about sessions here.
Sessions are usually sent by default to Sentry once you set a release name in your SDK init, unless you disable auto session tracking (there will be a respective option in the SDK of your choice). They can be viewed in the Releases page.
Sessions are not billed.
Replay Sessions
Session Replay allows you to see video-like reproductions of user sessions which can help you understand what happened before, during, and after an error or performance issue occurred.
Unlike sessions on the Releases page, user sessions in Session Replay can span multiple page loads.
Web

Replay sessions are billed as per our pricing page.
Exception: Mobile replay sessions are not billed yet, as they are still in Beta.
