TL;DR: Seq 2025.1 supports connecting system notifications to an output app instance to proactively receive notifications.
The Seq UI displays notifications when system events are detected, such as this notification that authentication is disabled.

System notifications include important events that may need to be addressed for Seq to continue operating, like low disk space or an indexing failure.
From Seq 2025.1 these notification can be connected to an output app instance (email, Slack, webhook etc.).
To receive notifications for system events:
- Setup an app instance that uses your preferred communication channel.
- Configure that app instance as the 'Target app instance' setting (Settings > General).

When Seq detects a notification event it will be sent via the configured app instance.
Seq 2025.1 is ready to try now: grab the binaries from https://datalust.co/download (look for the "preview" link) or pull datalust/seq:preview
from Docker Hub.
