Are you saying that Slack uses mod_php? According to a Slack Engineering blog post[0] from 9 months ago, Slack has been using Hack/HHVM since 2016 in place of PHP. My understanding is that HHVM can only be run over FastCGI, unless there's a mod_hhvm that I'm unaware of.

This is accurate: Slack is exclusively using Hack/HHVM for its application servers.

HHVM has an embedded web server (the folly project's Proxygen), and can directly terminate HTTP/HTTPS itself. Facebook uses it in this way. If you want to bring your own webserver, though, FastCGI is the most practical way to do so with HHVM.
