About Gemfile Review
Gemfile Review is an independent publication about the Ruby on Rails gem ecosystem. It is written for developers who have to decide which libraries to trust with their application, and for those maintaining older applications whose Gemfile still carries names from another decade.
What we publish
- Guides on how Rails extensions are built and distributed, and on how to evaluate, audit and upgrade the gems an application depends on.
- Category guides that compare the established options for one job, such as background jobs or file uploads, including the solutions that now ship with Rails itself.
- Plugin histories: short, factual notes on plugins that many older tutorials and Stack Overflow answers still mention, with their status today and the usual replacement.
How information is checked
Version numbers and release dates are taken from the public RubyGems.org API or the project's changelog at the time of writing, and the page says when a figure was checked. Claims about what a framework does are linked to the official Rails Guides, the API documentation or the gem's own repository. When the status of a project is unclear, for example a repository that has had no release for years but has not been formally archived, the page says so rather than guessing.
Gemfile Review has no commercial relationship with the projects it covers. Mentioning a gem is not an endorsement, and the guides do not rank libraries by popularity alone.
About this domain
From roughly 2010 to 2013 this domain hosted RailsPlugins.org, a community site where authors and users recorded whether Rails plugins and gems worked with Rails 3, Ruby 1.9, JRuby and thread-safe deployments. That service closed long ago; in later years the domain was used by unrelated sites, including German-language finance pages and, more recently, gambling content, none of which is continued here. Gemfile Review is a new and separate publication with no connection to the people who ran RailsPlugins.org or to the later owners. No text, data or images from any of those sites are reused. Old plugin addresses that still receive links now lead to new notes on the same plugins, or to the closest category guide.
Corrections
A gem can ship three releases in the time it takes to write about it. If a guide has fallen behind RubyGems.org or gets something wrong, the contact page says how to tell us; the company that publishes Gemfile Review is named in the legal notice.
