We use it on https://hsreplay.net https://hsreplay.net, which serves about 100-200k requests / day behind Cloudflare. Pros: It's super useful not to have to worry about HTTPS renewal. The caddyfiles are super simple. The Caddy code is beautiful to read and simple to understand. The plugin system is great. Cons: At load, we got bitten hard by the default proxy timeout behaviour. That particular issue has been fixed in 0.9.3 (fail_timeout). Haven't had any other issues, but it does feel pretty stressful to run unproven software in prod. Thankfully, we can easily switch back to nginx if we need to.
