@sun @3 @dushman @glitter @tk Caddy has one redeeming feature: the ability to write custom plugins in Go makes extending it very easy.

I have a module at work that stores all the TLS certificates in an S3 bucket. Any server in the "cluster" will have access to every certificate for every site being served. This is super useful when you can't rely on wildcards. Plus with the way I have it configured any server can initiate a certificate renewal/issuance and any other server can respond. It's magic (by using a dirty hack to forge HTTP-01 ACME responses)
