It’s also nice because it has ACME built right in (it takes care of your SSL/TLS certs for your site automatically without setting up a cron job or certbot yourself)
Yeah steep is putting it mildly, it's not worth it below a certain scale. What it excels at is highly dynamic environments where things get spun up and down on the regular and all with auto scaling.
I hate the non-static world of the web as it exists today, so I just pre-gen static HTML pages and serve them direct from Caddy; or reverse proxy some other service that's running its own delivery method. Jellyfin, Sonarr, Radarr, etc -- none of them need a "proper" web server running in front of them.
