CarrierWave is a Ruby gem providing a flexible, class-based solution for handling file uploads in Rack-based web applications such as Rails and Sinatra. It supports pluggable storage backends, image processing, and versioned file variants.
Use cases
- upload files in a Rails app
- handle avatar image uploads with resizing
- store uploads on S3 or local filesystem
- manage file attachments for ActiveRecord models
- generate thumbnail versions of uploaded images
- add file upload support to a Sinatra application
When to choose
- you are building a Ruby or Rails application that needs robust, customizable file uploads
- you want pluggable storage (local, S3, fog) and image processing in one gem
- you need versioned variants of uploaded files
When to avoid
- you are not using Ruby or a Rack-based framework
- you need a language-agnostic upload service rather than a Ruby library
- you prefer newer alternatives like Active Storage built into Rails
