If you want to DIY something, I have a bash script that builds OpenResty with NAXSI from source. Most of the web apps I write anymore are actually in Lua, for OpenResty, maybe with an API written in something else. But I also help other members of my team deploy their Node and Python apps and stuff, and I always just park those behind OpenResty with NAXSI, just doing a standard nginx reverse proxy.
