Choose Caddy if:
Anyone who wants a correctly configured HTTPS server without ceremony.
Choose Swagger if:
Teams publishing an API that other people have to consume.
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
Swagger: pros & cons
- OpenAPI is the industry standard
- Interactive docs from the same spec
- Client generation in many languages
- Specs drift from reality without discipline
- Generated clients need review
- Editor experience is dated
Our verdict on Caddy
The easiest path to good TLS defaults. nginx still wins on ecosystem and examples.
Our verdict on Swagger
Worth adopting for any public API. The spec only helps if you keep it truthful.
