Dragonfly is a Ruby gem for on-the-fly processing and management of images and other file attachments, with a Rack-based app that serves processed content via URLs. It integrates with Rails and Sinatra, supports pluggable processors, generators, analysers, and data stores such as S3.

Use cases

• generate image thumbnails on the fly in Rails
• manage file attachments on ActiveRecord models
• generate text images on demand in Sinatra
• convert uploaded audio files to mp3 and store them in S3
• serve resized images via URLs in a Rack app
• process uploads with custom processors

When to choose

• you need on-the-fly image resizing or thumbnailing in a Ruby web app
• you want a customizable attachment-handling layer for Rails or Sinatra
• you need pluggable datastores (e.g. S3) and custom processing jobs

When to avoid

• you are not using Ruby
• you prefer modern alternatives like Active Storage or Shrine for new Rails projects
• you need heavy non-image media processing pipelines
