PagerDuty and Checkly are often evaluated together by teams building out their reliability stack. PagerDuty (digital operations management and incident response, founded 2009) is typically a fit for DevOps Teams, SREs, and On-call Engineers, while Checkly (api and e2e monitoring for developer teams, founded 2018) leans toward Backend Developers, DevOps Teams, and QA Engineers. Both cover 8 of the same core capabilities, so the decision usually comes down to where they diverge.

Checkly covers more unique ground in this comparison, notably Synthetic Monitoring, API & Browser Testing, Uptime Monitoring, and Multi-Location Checks, among others. That said, PagerDuty (Free (5 users), Pro $21/user/mo, Business $41/user/mo (+ Add-ons)) is the better choice when Incident Management is a priority.
PagerDuty is digital operations management and incident response, while Checkly is api and e2e monitoring for developer teams. PagerDuty adds Incident Management on top of the shared feature set. Checkly brings Synthetic Monitoring, API & Browser Testing, and Uptime Monitoring that PagerDuty does not.
PagerDuty pricing: Free (5 users), Pro $21/user/mo, Business $41/user/mo (+ Add-ons). Checkly pricing: Hobby (Free), Starter $24/mo, Team $64/mo (100k API, 12k Browser runs). Evaluate against your check volume and team size; entry pricing rarely reflects total cost at scale.
PagerDuty is designed with DevOps Teams, SREs, and On-call Engineers in mind, whereas Checkly targets Backend Developers, DevOps Teams, and QA Engineers. If your team matches the former profile, PagerDuty is usually the closer fit.
No. It does a different job. On-call and status tools decide who gets paged and what customers see, but they need a detection layer feeding them. ObserveOne is that layer: scheduled synthetic checks on your critical journeys that catch the outage and hand it to your incident process.
On-call and status tools decide who gets paged and what customers see, but they need a detection layer feeding them. ObserveOne is that layer: scheduled synthetic checks on your critical journeys that catch the outage and hand it to your incident process. The free tier covers enough to try it on one critical journey.
Each tool has its own alternatives page too, not just this matchup.
