## What it is
React on Rails is a Ruby gem plus npm package that integrates React components into Ruby on Rails applications via view helpers, Shakapacker bundling, and server-side rendering. It supports hot module replacement, auto-bundling, Redux, i18n, and offers a Pro tier with React Server Components, streaming SSR, and a dedicated Node renderer.

## Use cases
- render react components in rails views
- server-side rendering of react for seo in a rails app
- add react to an existing ruby on rails application
- pass rails data to react components without building a separate api
- hot reloading react during rails development
- migrate from react-rails or webpacker to a modern react setup
- react server components with rails

## When to choose
- you have a Rails app and want React without building a separate API backend
- you need SSR of React components for SEO and fast initial page loads
- you want Rails conventions, asset pipeline, and view helpers with modern JS tooling
- you want a maintained integration with generators, tutorials, and commercial support options

## When to avoid
- you are building a standalone SPA or non-Rails backend
- you prefer Hotwire or Inertia-style approaches without a JS build pipeline
- you need RSC, streaming SSR, or high-throughput SSR on the free tier only
- your Rails version is older than 7.0 or Ruby older than 3.3
