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

Logz.io

  • SaaS-only with no self-hosting option
  • High pricing for long data retention periods, with steep cost increases for larger data volumes
  • UI can take up to 10 seconds to load
  • Geo-location data is old and inaccurate
  • Expensive for smaller companies with limited log volumes
  • Data retention limitations at 14 days may not meet compliance requirements

Logz.io: Is Logz.io based on open-source ELK Stack?

Logz.io is built on the ELK Stack (Elasticsearch, Logstash, Kibana) but uses managed hosting. Note that Elasticsearch and Kibana switched to non-open-source licenses (SSPL) in February 2021, which may have legal implications.
