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
GNU Emacs
- Steep learning curve for its default keybindings and Lisp-based configuration.
- Default UI looks dated compared to modern editors without heavy customization.
- Performance can lag on very large files compared to newer editors.
- Discoverability of features is poor without prior familiarity or external guides.
