Prometheus is the CNCF graduated monitoring system for metrics collection, storage, and alerting. Pull-based model with PromQL for powerful queries.
Reviewer scorecard
“The free tier is absurdly generous and the cold starts are essentially zero. For APIs, middleware, and edge logic, nothing else gives you this performance at this price.”
“The standard for metrics. PromQL is powerful, the ecosystem is massive, and it pairs perfectly with Grafana.”
“The Worker runtime has limitations — no Node.js stdlib, size limits, CPU time limits. Know the constraints. But for what it does well, it's unbeatable.”
“Battle-tested at every scale. The pull model and service discovery integration are well-designed.”
“Cloudflare is building the programmable internet. Workers + D1 + R2 + AI = a complete platform that runs at the edge. They're quietly becoming the default infrastructure layer.”
“Prometheus + Grafana is the open-source observability stack. Mimir extends it to global scale.”
