FAQ
Which is cheapest at scale?
Self-hosted Grafana stack by far. You pay only for infrastructure. At 100+ hosts, Datadog can cost $5,000+/month while Grafana self-hosted costs server time only.
I'm just starting — what should I use?
New Relic free tier (100GB/month). It includes everything. Upgrade when you outgrow it.
Can I use Grafana dashboards with Datadog/New Relic?
Yes. Grafana connects to Datadog and New Relic as data sources. Some teams use Grafana for dashboards and Datadog for data collection.
What about BetterStack/Axiom?
Both are excellent modern alternatives. BetterStack combines uptime monitoring, logs, and incident management. Axiom offers generous free log ingestion. Good for startups.
