Prometheus
Pros
- + Free and open source under Apache 2.0 with independent CNCF governance — no per-node or per-metric licensing
- + The industry-standard metrics stack: PromQL, multidimensional labels, and exporters for most software you already run
- + Kubernetes and Consul service discovery keep target configuration sane at container scale
- + Simple core: single autonomous nodes with local TSDB and a documented operational model
- + CNCF graduated since 2018 with a decade of production history and a very active contributor community
- + Honest documentation — storage constraints and the security model are stated plainly, including what the product deliberately does not do
Cons
- - No built-in long-term storage or global HA — Thanos, Cortex, or Grafana Mimir are separate operational projects
- - High-cardinality labels can blow up RAM and disk with no guardrails in the product
- - No built-in authentication or encryption; endpoints must be kept behind a perimeter by design
- - Multi-tenancy and access control are absent from the core
- - Community support only for the open-source download — SLAs come with paid managed offerings
- - PromQL and histogram handling have a genuine learning curve for teams new to the model
Netdata
Pros
- + Free Community tier is a real deployment: up to 5 active nodes with per-second metrics and local storage
- + Flat per-node pricing ($4.50/node/month billed annually on Business) — no ingest, cardinality, seat, or retention charges
- + Agent is open source (GPLv3+) with 80,000+ GitHub stars and 690+ contributors; data stays on your own infrastructure
- + 800+ integrations plus Prometheus, OpenTelemetry/OTLP, StatsD, SNMP, eBPF, and Nagios plugin support
- + ML anomaly detection runs in the agent at every metric, not as a paid add-on
Cons
- - Centralized dashboards cap at 5 nodes and custom dashboards at 1 per room on the free tier
- - RBAC, SSO, and SCIM require the Business tier even for small teams
- - No published uptime SLA for Netdata Cloud; priority support is an Enterprise On-Premise item
- - Operating at scale requires provisioning tooling (Ansible/Terraform-like) for consistent agent configuration
- - Dashboard customization is more limited than fully programmable alternatives; larger fleets effectively need Netdata Cloud
