The short version

  • Only ELK Stack has a free tier, so it costs nothing to try first.
  • Each has a real cost: Elastic the 99.95% monthly uptime SLA is only offered on the Platinum and Enterprise subscription tiers of Hosted deployments, not on lower tiers, per elastic.co, August 2026; 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

  • 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

  • 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
