It's an awesome project and I imagine it has saved countless production incidents. The amount of times I've said "it was probably certificate expiry" and been correct is reasonably high.
In my own cases of responsibility, Caddy would have eliminated them had it been around. Instead I've learned to be paranoid, though having things like this are far better in terms of easing cognitive burden.
Cheers for all of the hard work by you and other maintainers.
I too have used Caddy on multiple production systems. It's a great bit of software.
I try to avoid engaging in online flame wars but I will say that the developers - including Francis - have been nothing but helpful and courteous to me personally and I've also learned a lot from their numerous positive contributions to Caddy-related forums.
