Rails application preloader

Spring speeds up development by keeping your application running in the background so you don't need to boot it every time you run a test, rake task or migration.

Features

  • Totally automatic; no need to explicitly start and stop the background process
  • Reloads your application code on each run
  • Restarts your application when configs / initializers / gem dependencies are changed

Compatibility

  • Ruby versions: MRI 1.9.3, MRI 2.0, MRI 2.1, MRI 2.2
  • Rails versions: 4.0+ (in Rails 4.1 and up Spring is included by default)

Spring makes extensive use of Process.fork, so won't be able to provide a speed up on platforms which don't support forking (, ).
