The HN source base is a monolithic Arc program and Arc is in Racket/Scheme. To use Workers I would have had to get Racket working on Wasm which I simply haven't tried. Also news.arc does a bunch of file system access and I'd have to rewrite that to use Workers KV or something. So, I decided to use lots of Cloudflare and run the Arc code on a VPS I've had for many years. The whole thing is running in a screen session which I can hop into and be in the REPL when I want.
