| Compare | GreptimeDB | Datadog |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Platform teams at scale | Mid-to-large engineering orgs |
| Who it's not for | Small teams that just need basic metrics dashboards | Small teams or side projects on a budget |
| Privacy | No known public vulnerabilities found in the sources reviewed.² | No confirmed platform breach in reviewed sources; agent components carry published CVEs and a 2016 incident is documented.14 |
| Support quality | No user evidence available | No support evidence in reviewed sources |
| Public sentiment | Public user feedback is scarce; the only direct comment found is a brief positive social post with no verifiable detail.³ | Users praise the unified visibility and integration depth, but cost is the loudest complaint across Reddit and review sites.⁵ |
| Biggest gotcha | Open-source core, but cloud/managed pricing isn't published . expect a sales call before budgeting¹ | Multi-dimensional billing: hosts, logs, APM, synthetics each metered separately⁹ |
