Datadog gives you world-class observability — then bills you for every byte. REMS gives you the same unified visibility, active AI investigation, and full data sovereignty, at 50–70% lower cost.
Every dimension that matters — cost, AI, privacy, flexibility, and ease of use.

Pricing models that penalise growth vs infrastructure-only costs that scale cleanly.
Verified reviews from G2, Capterra, Gartner Peer Insights & TrustRadius.
Pricing can become really expensive at scale, especially when log ingestion and custom metrics are not carefully managed. I wish there was a cost dashboard to track spend before you get hit with the bill.
Cost ShockIn the beginning there is so much information on the screen. It's hard to know what is a link, what is important and what is not. The complex billing system trips up most new users.
UI ComplexityCosts rise quickly with added features and data retention. We were told to remove log sources or face account closure — that was not customer-friendly at all.
Billing PressureWe started sampling logs to reduce cost — but then we kept missing critical error context during incidents. The trade-off is painful and shouldn't have to exist.
Forced SamplingThe fundamental difference between REMS and Datadog on AI is not feature depth — it's the entire paradigm.
