Is Caddy or Namespace better?

Neither clearly leads. Caddy starts at Free and Namespace at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Caddy or Namespace?

Caddy starts at Free and Namespace at Free.

Does Caddy or Namespace run on more platforms?

Caddy runs on Linux, macOS, Windows, Docker. Namespace runs on Cloud, Mac, Windows, Linux.

Can I use Caddy for free?

Both have a free tier, so you can try either at no cost before committing.

What is Caddy best used for?

Caddy is most often used for sites and services where expired certificates have caused outages before, small deployments where nginx configuration is more effort than the problem warrants, reverse proxying internal services with tls without a certificate workflow. Of those, sites and services where expired certificates have caused outages before and small deployments where nginx configuration is more effort than the problem warrants are not what Namespace is typically brought in for.

What can Caddy do that Namespace cannot?

Caddy covers Automatic HTTPS, Caddyfile, Reverse proxy, Single binary. Namespace covers Devboxes, GitHub Actions runners, Docker builds, Cross-invocation caching.

The short version

Each has a real cost: Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer; Namespace developer plan is pay-as-you-go only; minimum usage unclear

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

Namespace

Developer plan is pay-as-you-go only; minimum usage unclear
Team plan $100/mo is competitive but usage limits may be tight
Devbox pricing separate at $0.004/minute could add up quickly
Enterprise plan requires custom sales conversation
