Grafana vs Datadog (2026): Which Observability Platform Should You Choose?
By Alex Chen · นักวิเคราะห์ SaaS · อัพเดท เมษายน 11, 2026 · Based on hands-on infrastructure testing
คำตอบใน 30 วินาที
เลือก Grafana (+ Prometheus, Loki, Tempo) if you want full control, open-source freedom, and dramatically lower มีค่าใช้จ่าย — but have engineers who can maintain the stack. เลือก Datadogif you want unified APM + logs + metrics + traces out of the box with zero infrastructure to manage. Grafana ชนะ 5-3 on cost and flexibility, but Datadog's ครบวงจร convenience is genuinely valuable for ทีม that can afford it.

Which do you use?
ใครควรเลือกอะไร?
→ เลือก Grafana if:
You want full control over your observability stack, want to minimize SaaS costs, have engineers who can maintain Prometheus + Loki + Tempo, or need to avoid vendor lock-in. The LGTM stack is the gold standard for cost-conscious DevOps teams.
→ เลือก Datadog if:
You need unified APM, logs, metrics, and traces without managing infrastructure. Your company can afford the premium and values time-to-insight over cost optimization. You don't have dedicated platform engineers.
→ ควรหลีกเลี่ยงทั้งคู่ถ้า:
You're a small team with พื้นฐาน monitoring needs — try Uptime Robot (free) for availability monitoring or New Relic's generous free tier (100GB/เดือน) for full-stack observability.

คำถามที่พบบ่อย
ความเห็นบรรณาธิการ
I've built observability stacks with both. Datadog gets you from zero to แดชบอร์ด in an afternoon — it's genuinely magical. But when I saw the first $40K/เดือน invoice at a previous company, we migrated to Grafana + Prometheus in a month and cut มีค่าใช้จ่าย by 80%. The catch? We needed two engineers maintaining it. If you have the people, go Grafana. If you don't, Datadog's premium is worth it.
