Frequently Asked Questions

Which observability platform is cheapest?
Self-hosted Prometheus + Grafana has zero software cost. Among managed platforms, Grafana Cloud is typically cheapest due to usage-based pricing with a generous free tier (10K series, 50 GB logs). New Relic offers the best free tier for a fully managed platform (100 GB/month data ingest). SigNoz Cloud is very competitive at $49/month base with $0.30/GB for logs and traces.
Which platform is best for startups?
New Relic for managed simplicity (100 GB free, data-ingest pricing, no per-host fees). Grafana Cloud free tier for teams comfortable with the Prometheus ecosystem. For zero-budget startups, self-hosted SigNoz or Prometheus + Grafana provide full capability at no software cost.
Which platform has the best Kubernetes support?
Prometheus is the native K8s monitoring tool, designed specifically for container environments with built-in service discovery. Datadog has the most polished K8s UX with auto-discovery, container maps, and Cluster Agent. Dynatrace OneAgent provides automatic topology mapping on K8s. For cost-conscious K8s teams, Prometheus or Grafana Cloud (managed Prometheus) are the standard choices.
Which platform supports OpenTelemetry best?
Honeycomb and SigNoz are the most OTel-native platforms, built from the ground up on OpenTelemetry. Grafana Cloud fully supports OTel via OTLP for metrics, traces, and logs. New Relic and Dynatrace accept OTel data alongside their native agents. Datadog supports OTel but still recommends its proprietary agent for the best experience.
