Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Caddy
- Smaller ecosystem than Nginx, so third-party guides and modules are fewer
- Adding plugins means rebuilding the binary rather than loading a module
- Under very high throughput Nginx generally still benchmarks ahead
- Automatic certificate issuance needs outbound internet access, which complicates air-gapped deployments
Render
- The free Hobby workspace is limited to 25 services and 5 GB of bandwidth
- Every paid plan charges the workspace fee plus compute on top, so $25 per month for Pro is a floor rather than a total
- SAML SSO and SCIM require the Scale plan at $499 per month
- HIPAA-compliant workspaces, inbound IP rules and advanced RBAC roles are Scale plan features
- Organization-level audit logs require Scale; Pro provides only workspace audit logs
- Contractual uptime SLAs, support response SLAs and a technical account manager are Enterprise only, and Enterprise is custom priced with no published rate
- Included bandwidth is 25 GB on Pro and 1 TB on Scale, with usage beyond that billed separately
