Reviewer scorecard
“The standard for metrics. PromQL is powerful, the ecosystem is massive, and it pairs perfectly with Grafana.”
“Essential for any production app. Source maps, breadcrumbs, and release tracking make debugging 10x faster.”
“Battle-tested at every scale. The pull model and service discovery integration are well-designed.”
“The free tier is generous and the core error tracking is genuinely best-in-class. Session replay is a nice bonus.”
“Prometheus + Grafana is the open-source observability stack. Mimir extends it to global scale.”
“Session replay lets you see exactly what users experienced before errors. Invaluable for debugging UI issues.”
