Prometheus
Depends
Confidence: Medium

| Compare | GreptimeDB | Prometheus |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Platform teams at scale | Kubernetes and container monitoring |
| Who it's not for | Small teams that just need basic metrics dashboards | Non-technical teams wanting turnkey hosting |
| Privacy | No known public vulnerabilities found in the sources reviewed.² | Security model is documented, but 2026 brought XSS and DoS CVEs, and misconfigured public exposure is the top real-world risk. |
| Support quality | No user evidence available | No support evidence in sources |
| Public sentiment | Public user feedback is scarce; the only direct comment found is a brief positive social post with no verifiable detail.³ | Adoption is enormous . 68,598 companies tracked . yet teams routinely evaluate simpler or cheaper alternatives.⁷ |
| Biggest gotcha | Open-source core, but cloud/managed pricing isn't published . expect a sales call before budgeting¹ | Over 330K instances exposed to DoS attacks and data compromise in Dec 2024; never expose it publicly11 |
