Key point
Pick by runtime
A host is not just a place to upload files. It must run the thing your project needs in production.
Choose by runtime first: static files, server-side app, API server, or database-backed full-stack app. Price and custom domain come after that.
Know your app type
A React, Vite, or plain HTML app that only calls external APIs can be hosted as a static frontend. It builds into files like index.html, CSS, and JavaScript.
A Next.js app with server routes, an Express API, or a Django backend needs a host that runs server code. If your app writes user data, you will also need a hosted database later.
