A Ruby gem that automatically adds vendor prefixes to CSS rules using values from the Can I Use database.
Autoprefixer Rails is a Ruby gem that integrates Autoprefixer into Ruby and Ruby on Rails applications. It automatically adds vendor prefixes to CSS rules by parsing stylesheets and using data from the Can I Use database, solving the problem of manual CSS prefix management for cross-browser compatibility.
Ruby and Rails developers who need to ensure their CSS works across different browsers without manually writing vendor-specific prefixes, particularly those using the Asset Pipeline or Sprockets.
Developers choose Autoprefixer Rails because it automates a tedious part of CSS development, reduces errors from missing prefixes, and keeps stylesheets clean and maintainable by leveraging the widely trusted Autoprefixer tool within the Ruby ecosystem.

Directly integrates with the Rails Asset Pipeline and Sprockets, allowing automatic CSS processing without complex setup, as shown in the README's usage examples.
Leverages the Can I Use database to add vendor prefixes automatically, eliminating manual CSS prefix work and reducing cross-browser compatibility errors.
Supports .browserslistrc files for customizing target browsers, enabling teams to tailor prefixing based on project requirements.
Generates or modifies source maps during processing, maintaining debuggability in the build pipeline, which is detailed in the README's options.
Missing key Autoprefixer features like browser configuration in package.json and custom usage statistics, as admitted in the README's 'Differences' section.
Requires Node.js on Windows and has compatibility issues with runtimes like therubyracer, adding setup complexity and potential environment hurdles.
In Rails, changes to browser configurations necessitate manual cache clearing (rake tmp:clear), which can be error-prone and disrupt workflow.
