Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Sematext
- The $5 Basic plan caps ingestion at 500 MB a day and retains logs for 7 days
- Ingestion and storage are billed on separate meters, at $0.10 per GB received and $0.15 per GB stored
- Retention is a plan property rather than a setting, so keeping logs longer means moving tier
- The published pricing page renders Standard and Pro figures from unresolved template placeholders, so only the Basic numbers are actually readable
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
