Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Consul
- Namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only
- Audit logging, OIDC authentication and FIPS 140-2 builds require Consul Enterprise, so compliance driven deployments cannot use the free edition
- Automated backups, redundancy zones, read replicas and automated server upgrades are Enterprise only
- Long Term Support releases are Enterprise only, so community users must upgrade to stay supported
- Service mesh and advanced traffic management sit in the Premium Enterprise tier above Standard Enterprise
- HashiCorp does not publish a Consul rate on its pricing page, which lists per resource prices for Terraform instead
Splunk
- No prices are published on any plan; every model requires contacting sales for an estimate
- Three separate pricing models, workload, ingest and entity, so the same deployment costs different amounts depending on which was signed
- Ingest pricing bills on data volume, so cost tracks how much you log rather than how much value you get from it
- Security, observability and platform are priced separately
