Grafana and Sentry are often evaluated together by teams building out their reliability stack. Grafana (open-source observability and data visualization, founded 2014) is typically a fit for Engineers, SREs, and Data Teams, while Sentry (application error monitoring and performance management, founded 2012) leans toward Developers, Frontend Teams, and Backend Engineers. Both cover 10 of the same core capabilities, so the decision usually comes down to where they diverge.

On capability breadth, Grafana pulls ahead here: it uniquely offers Synthetic Monitoring, API & Browser Testing, Multi-Location Checks, and SSL Monitoring, among others. Choose Grafana if those matter to your workflow; Sentry (Developer (Free - 5k errors), Team from ~$26/mo, Business from ~$80/mo) remains a solid option if you want a simpler, focused tool.
Grafana is open-source observability and data visualization, while Sentry is application error monitoring and performance management. Grafana adds Synthetic Monitoring, API & Browser Testing, and Multi-Location Checks on top of the shared feature set.
Grafana pricing: Open source free, Cloud from $0 (scalable usage-based). Sentry pricing: Developer (Free - 5k errors), Team from ~$26/mo, Business from ~$80/mo. Evaluate against your check volume and team size; entry pricing rarely reflects total cost at scale.
Grafana is designed with Engineers, SREs, and Data Teams in mind, whereas Sentry targets Developers, Frontend Teams, and Backend Engineers. If your team matches the former profile, Grafana 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.

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.
