Feature flag context provides deeper insight into the state of your application prior to an error. It can help you understand if a feature flag change is correlated with a new issue, as well as help you reproduce your users' application state at the time of an error.

Sentry now supports reflecting feature flag details on our Issue Details page:

• Evaluation tracking; See all feature flags evaluated on an error event, in evaluation order. They will appear in the "Feature Flag" section of the Issue Details page as a table, with "suspect" flag predictions highlighted in yellow.

• Change tracking: Understand feature flag changes (e.g., introducing a new flag or deleting one) in relation to the error volume of a given issue. This audit log appears in the "event volume" chart and presents itself as a vertical line.

Prerequisites

Feature flag context is powered by integrations with LaunchDarkly and OpenFeature today, and requires either a Python or JavaScript project. More information can be found in our documentation.
