When you say you want to build something simple with a few pages, you might be able to get by with something minimalist like Flask and maybe DataTables: https://datatables.net/

If you don’t expect to have scalability or real-time needs, I would not really recommend Elixir/Phoenix. The core language, dev tools, docs, and OTP are best-in-class, but there’s a learning curve, and the ecosystem has less mindshare than Python and Ruby.

I personally prefer Python/Django with htmx for client-side interactivity (if you need it), but if you want something better-integrated out of the box, you can’t go wrong with Ruby/Rails/Hotwire either.

Using a VPS is cheap and initially simple, but keep in mind you have to do more setup and maintenance on the OS, Web server, database, etc. yourself. I’ve had a great experience with DigitalOcean VPSs in the past, but for the app I’m building now, I am leaning toward using their managed app platform to minimize sysadmin/infra work on my part.
