## What it is
render_async is a Ruby gem for Rails that speeds up page loads by rendering view partials asynchronously via AJAX. It injects JavaScript that fetches a controller action and renders the partial in place, letting users see the page shell faster.

## Use cases
- speed up slow Rails pages by loading partials asynchronously
- render dashboard widgets without blocking page load
- lazy-load heavy view sections with AJAX in Rails
- avoid caching problems caused by slow partials
- load page sections after initial render in Rails 5+

## When to choose
- you have a Rails app with slow-rendering partials blocking page display
- you want a simple view-helper-based async loading without a JavaScript framework
- you need to defer expensive content until after the page shell renders

## When to avoid
- you use Hotwire/Turbo or a modern SPA framework that already handles async content
- your project is not Ruby on Rails
- you need server-sent events or streaming rather than simple AJAX fetch-and-render
