Does Hotwire/Turbo/Stimulus still require running a server? I really like my setup of Svelte front-end, serverless functions on Zeit that do all the data handling, and Airtable "back-end" for collecting form data. Svelte compiles everything so it's lightning fast and I don't have to pay for servers. I'm not sure how Hotwire is more "modest" than that if it requires a server running at all times...
