Datadog is powerful, but US-based and per-metric priced. monsys.ai covers the core for server teams (infrastructure monitoring, log signals, alerts, compliance reports, AI observability) at a flat price per server with data that stays in the EU.
€3 per server per month from the sixth server, the first 5 free. No stacking of per-host, per-metric, per-log and per-user pricing.
Hosted in Belgium by GoTrust BV. No third-country transfer for your operational data, which saves questions in GDPR and NIS2 trajectories.
Ed25519-signed audit packs and on-demand reports. Evidence is a core feature of monsys.ai, not an add-on.
No. For hyperscale APM tracing and hundreds of SaaS integrations Datadog remains stronger. For server monitoring, compliance evidence and AI observability at a flat price, monsys.ai is the simpler, sovereign alternative.
For server monitoring: one install command per server, no application instrumentation needed. Most teams see their fleet in the dashboard within an hour.
Datadog Infrastructure starts around $15 per host per month, excluding logs and extra products. monsys.ai costs €3 per server per month from the sixth server, everything included, and the first 5 servers are free.
In Belgium, operated by GoTrust BV under European law. Authentication, alerts and reporting run without US SaaS services.
