I've had a really good time with Caddy on a hobby project over the past 7 years on a digital ocean droplet.
Automatic HTTPS, multiple domains, proxying specific routes to local services, etc etc, managed by one extremely legible config file.
I've had literally one service failure over that period, and it was my own error after running upgrades of the droplet's operating system.
Highly recommended.
Congrats to Mike on growing the project to the point where he can responsibly take a hand off the wheel now and then. And thank you!
