Sentry and PagerDuty are often evaluated together by teams building out their reliability stack. Sentry (application error monitoring and performance management, founded 2012) is typically a fit for Developers, Frontend Teams, and Backend Engineers, while PagerDuty (digital operations management and incident response, founded 2009) leans toward DevOps Teams, SREs, and On-call Engineers. Both cover 7 of the same core capabilities, so the decision usually comes down to where they diverge.
On capability breadth, Sentry pulls ahead here: it uniquely offers Real User Monitoring, Uptime Monitoring, and On-Premise / Self-Host. Choose Sentry if those matter to your workflow; PagerDuty (Free (5 users), Pro $21/user/mo, Business $41/user/mo (+ Add-ons)) remains a solid option if Status Page and Incident Management is what you need.

Sentry is application error monitoring and performance management, while PagerDuty is digital operations management and incident response. Sentry adds Real User Monitoring, Uptime Monitoring, and On-Premise / Self-Host on top of the shared feature set. PagerDuty brings Status Page and Incident Management that Sentry does not.
Sentry pricing: Developer (Free - 5k errors), Team from ~$26/mo, Business from ~$80/mo. PagerDuty pricing: Free (5 users), Pro $21/user/mo, Business $41/user/mo (+ Add-ons). Evaluate against your check volume and team size; entry pricing rarely reflects total cost at scale.
Sentry is designed with Developers, Frontend Teams, and Backend Engineers in mind, whereas PagerDuty targets DevOps Teams, SREs, and On-call Engineers. If your team matches the former profile, Sentry is usually the closer fit.
No. It does a different job. Error trackers tell you an exception fired. They can't see the failures that never throw: a checkout that silently breaks, an expired SSL certificate, a page that returns 200 and renders blank. ObserveOne monitors those user-facing journeys in production; teams run it alongside an error tracker, not instead of one.
Error trackers tell you an exception fired. They can't see the failures that never throw: a checkout that silently breaks, an expired SSL certificate, a page that returns 200 and renders blank. ObserveOne monitors those user-facing journeys in production; teams run it alongside an error tracker, not instead of one. The free tier covers enough to try it on one critical journey.
Each tool has its own alternatives page too, not just this matchup.
