The short version
- Only ELK Stack has a free tier, so it costs nothing to try first.
- Each has a real cost: ELK Stack the free Basic self managed subscription excludes machine learning, alerting, single sign on via SAML or OpenID Connect, LDAP and Active Directory authentication, field and document level security, searchable snapshots and cross cluster replication; Datadog Logs complex, multi-tiered pricing model based on ingestion, indexing, and storage; can become expensive at scale
- They diverge on capability: ELK Stack covers Data visualization, Datadog Logs covers Log ingestion.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
ELK Stack
- The free Basic self managed subscription excludes machine learning, alerting, single sign on via SAML or OpenID Connect, LDAP and Active Directory authentication, field and document level security, searchable snapshots and cross cluster replication
- Cross cluster operations require the same subscription tier on every cluster involved
- The 99.95 percent monthly uptime SLA applies only to the Platinum and Enterprise subscription tiers
- Three deployment models are priced on three different bases: resource based for Cloud Hosted, usage based for Serverless and licence based on nodes and RAM for self managed
- Elastic Cloud Serverless does not yet support traffic filtering, cross project search or bring your own key
- The pricing page publishes no rate for any tier
Datadog Logs
- Complex, multi-tiered pricing model based on ingestion, indexing, and storage; can become expensive at scale
- Ingestion pricing of $0.10/GB can accumulate rapidly for high-volume logging environments
