Grafana vs Kibana (2026): Which Observability Platform Wins?
By ToolVS Research Team · Updated April 10, 2026 · Based on hands-on testing
30-Second Answer
Pick Grafana for metrics visualization, time-series dashboards, and multi-datasource monitoring (Prometheus, InfluxDB, CloudWatch). Pick Kibana if you are on the Elastic Stack and need log analysis, full-text search, and SIEM security analytics. Many teams run both — Grafana for metrics, Kibana for logs.
Our Verdict
Grafana
- 70+ data source plugins (Prometheus, InfluxDB, AWS)
- Industry-standard for time-series dashboards
- Grafana LGTM stack (Logs, Metrics, Traces)
- Log analysis less powerful than Kibana
- Alerting historically complex
- Full-text search not its strength
Kibana
- Best-in-class log analysis with Elasticsearch
- Full-text search across all log data
- SIEM for security monitoring
- Tightly coupled to Elasticsearch only
- Elasticsearch can be expensive to run at scale
- License restrictions (Elastic License 2.0)
Side-by-Side Comparison
| Category | Grafana | Kibana | Winner |
|---|---|---|---|
| Metrics Visualization | Industry-leading | Good via Metricbeat | ✔ Grafana |
| Log Analysis | Loki (good) | Elasticsearch (best-in-class) | ✔ Kibana |
| Data Sources | 70+ sources (any datasource) | Elasticsearch only | ✔ Grafana |
| Full-Text Search | Limited | Best-in-class (Lucene) | ✔ Kibana |
| SIEM / Security | Basic | Full SIEM capabilities | ✔ Kibana |
| Free Cloud Tier | Yes — 10K series, 50GB logs | No free cloud tier | ✔ Grafana |
| License | AGPL (truly open) | Elastic License 2.0 (restricted) | ✔ Grafana |
| APM / Tracing | Tempo (good) | Elastic APM (comprehensive) | ✔ Kibana |
Which do you use?
Who Should Choose What?
Choose Grafana if:
You use Prometheus for metrics, need to aggregate multiple data sources in one dashboard, want a free cloud tier, or need the most widely-adopted open-source observability platform.
Choose Kibana if:
You are already using Elasticsearch for log ingestion, need powerful full-text search across logs, or want SIEM security analytics and APM in one platform.
Use both:
Many DevOps teams use Grafana for infrastructure metrics (Prometheus) and Kibana for application logs (Elasticsearch). They complement each other well.
