Agreed. Haproxy is an absolute wonder compared to similar systems. It all just feels so much cleaner, thought out, and built from the ground up for many different use cases. It very much has a feel that reminds me a lot of the spirit of sqlite.

Yeah. Stringency and rigor are words that come to mind.

What about nginx? I'm not too familiar but I was under the impression that it was the safe choice

It's primary focus is/was being a web server - a faster Apache. This shows.

Also (after the acqusition by F5 in 2019?) more features are kept away from the open source version compared to HAProxy.

How does it compare with Caddy?

Caddy is a bit quick and dirty, rapidly-developing, with neat plugins but hard to configure for more complex scenarios and too light on the docs (IMO).

HA Proxy is robust, comprehensive, mature, and bulletproof. It's basically boring because it works so well.

If you have to choose only one to learn, choose HA Proxy.

I wanted to try it out just now but hit a roadblock immediately - it cannot automatically obtain and maintain TLS certificates. You have to use an external client (e.g. acme.sh), set up a cron to check/renew them, and poke HAProxy to reload them if necessary. I'm way past doing this in 2023.

If getting Let's Encrypt to work with HAProxy is your only struggle, you'll soon overcome it and be loving HAProxy. And there are multiple ways to set up Let's Encrypt, if you don't want to use acme.sh. For example, you could use certbot. There are blog posts that cover that pretty well.

you may wish to use certbot instead:
