Grafana vs Uptime Kuma: Full Observability vs Simple Monitoring

These aren't really competitors — they solve different problems at different scales. Grafana is a complete observability platform for metrics, logs, traces, and dashboards. Uptime Kuma is a focused uptime monitor that checks if your services are up and alerts you when they're not. But the question "should I use Grafana or Uptime Kuma?" comes up often. Here's the answer.

Quick Verdict

Choose Grafana when you need full observability — infrastructure metrics, application logs, distributed traces, and custom dashboards. Choose Uptime Kuma when you just need to know if things are up and get notified when they're down.

The Comparison

Feature	Grafana (Stack)	Uptime Kuma
Primary purpose	Full observability	Uptime monitoring
Metrics	✅ (Prometheus/Mimir)	Response time only
Logs	✅ (Loki)	❌
Traces	✅ (Tempo)	❌
Dashboards	✅ (best in class)	Basic charts
Uptime monitoring	✅ (with plugins)	✅ (core feature)
Status pages	❌ (separate tool)	✅
Monitor types	Depends on setup	20+ built-in
Notifications	✅ (alerting rules)	90+ channels
Alert complexity	✅ (PromQL-based)	Simple up/down
Custom queries	PromQL, LogQL, TraceQL	❌
Data sources	100+	Built-in only
Setup complexity	Medium-High	Very Low
Components	3-5+ services	1 container
RAM usage	2-8+ GB (stack)	256-512 MB
Learning curve	Steep	Minimal
Stars	66K+ (Grafana)	62K+
License	AGPL-3.0	MIT

When to Choose Grafana

• Infrastructure monitoring (CPU, memory, disk, network across hosts)
• Application performance monitoring (APM)
• Log aggregation and search
• Distributed tracing
• Custom dashboards for business metrics
• Complex alerting rules (alert when error rate > 5% AND latency p99 > 500ms)
• You have a DevOps/SRE team
• You're running more than 5-10 services

When to Choose Uptime Kuma

• You just need to know: "Is my site up?"
• Simple alerting (down → notify)
• Public status pages for your users
• Small infrastructure (< 10 services)
• No DevOps team or monitoring expertise
• Docker container health checks
• SSL certificate expiry monitoring
• Quick setup without complexity

Use Both

The best answer for growing teams is often "use both":

Uptime Kuma → External uptime checks, status pages, simple alerts
     +
Grafana → Internal metrics, logs, traces, deep analysis

Uptime Kuma tells you something is down. Grafana tells you why it's down. They're complementary, not competing.

Setup Comparison

Uptime Kuma — running in 30 seconds:

docker run -d -p 3001:3001 -v uptime-kuma:/app/data louislam/uptime-kuma:1

Grafana + Prometheus — minimum viable stack:

# docker-compose.yml
services:
  prometheus:
    image: prom/prometheus:latest
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
    ports:
      - "9090:9090"
  grafana:
    image: grafana/grafana:latest
    ports:
      - "3000:3000"
    environment:
      - GF_AUTH_ANONYMOUS_ENABLED=true

Plus you need to configure Prometheus scrape targets, set up exporters on your services, create Grafana dashboards, and configure alert rules. Much more work, but much more capability.

The Bottom Line

Don't overthink this. If you're asking "Grafana or Uptime Kuma?" the answer is usually:

• Just starting out? → Uptime Kuma. Set it up in 30 seconds, monitor your services, get alerts.
• Growing infrastructure? → Add Grafana. Keep Uptime Kuma for external checks, add Grafana for internal observability.
• Serious production systems? → Full Grafana stack. Prometheus for metrics, Loki for logs, Tempo for traces.

They're different tools at different points on the complexity spectrum. Most teams eventually use both.
