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

RubyMine

No permanently free tier for commercial use; requires an ongoing subscription.
More resource-intensive than lightweight editors such as Sublime Text.
Focused primarily on Ruby, so polyglot teams may prefer IntelliJ IDEA Ultimate with plugins instead.
Startup time can be slower than simpler text editors on older hardware.
