Choose Caddy if:
Anyone who wants a correctly configured HTTPS server without ceremony.
Choose CircleCI if:
Engineering teams that want a dedicated CI service rather than whatever ships with their Git host.
Caddy: pros & cons
- HTTPS configured correctly by default
- Configuration is short and legible
- Single binary, easy to deploy
- Smaller community than nginx
- Fewer third-party guides
- Some advanced setups need plugins
CircleCI: pros & cons
- Fast builds with good caching and parallelism
- Docker-first, so local and CI environments match
- Works across GitHub, Bitbucket and GitLab
- Pricing by credits is hard to predict
- Configuration gets complex on large monorepos
- Debugging failed builds can be slow
Our verdict on Caddy
The easiest path to good TLS defaults. nginx still wins on ecosystem and examples.
Our verdict on CircleCI
Strong if CI is a bottleneck for you. If your pipelines are simple, the CI built into your Git host is probably enough.
