Nightjar, the Redis Streams Watcher That Wants to Fix Incidents

Field notes

Nightjar says it watches Redis Stream consumer groups and nearby Node.js service signals, then joins lag, pending-entry-list growth, and stall events into a shared incident timeline. Its proposed control boundary is unusually explicit: reversible actions may run automatically, while data changes, large job replays, and deploy rollbacks require a PagerDuty approval link with a Slack summary. The site also states that initial onboarding begins with one stream and generally takes about a day.
