Grafana is the visualisation layer that sits above other systems rather than a monitoring stack of its own. It queries Prometheus, Loki, PostgreSQL, ClickHouse, and dozens of other sources, and puts them on the same dashboard.

GlitchTip accepts events from the official Sentry SDKs, which means adopting it is a DSN change rather than an instrumentation project. Stack traces, breadcrumbs, releases, and issue grouping all work as expected.

Datadog

Infrastructure monitoring, logs, and tracing in one platform

Datadog's value is correlation. A latency spike on a dashboard, the traces behind it, and the logs from the affected hosts are one or two clicks apart, which is the difference between a ten minute incident and an hour.

Sentry is the tool most teams install first and remove last. An unhandled exception arrives with a stack trace, the release that introduced it, the users affected, and the breadcrumbs leading up to it.
