PagerDuty Notifier is a Chrome add-on developed by Rich Adams that provides desktop notifications for your PagerDuty incidents. With this add-on, you can receive real-time notifications on your desktop whenever a new incident is triggered in PagerDuty.

The main feature of PagerDuty Notifier is its ability to display newly triggered incidents as desktop notifications. This allows you to quickly acknowledge and resolve incidents directly from the notification, without having to open the PagerDuty web interface.

Additionally, PagerDuty Notifier offers customizable options to control which incidents you receive notifications for. You can choose to filter notifications based on urgency (high vs low), specific users, or specific services. This level of customization ensures that you only receive notifications for incidents that are relevant to you.

It is important to note that PagerDuty Notifier should not be relied upon as your primary alert mechanism. The add-on does not provide delivery guarantees, so it is strongly recommended to also have phone and SMS notifications set up in your PagerDuty profile for maximum alerting reliability.

Overall, PagerDuty Notifier is a useful tool for PagerDuty users who want to stay updated on their incidents in real-time, right from their desktop.
