Inspired by the ease of installing and setting up fitter-happier as a Rails application's health check, but frustrated by its lack of flexibility, OK Computer was born. It provides a robust endpoint to perform server health checks with a set of built-in plugins, as well as a simple interface to add your own custom checks.

For more insight into why we built this, check out our blog post introducing OK Computer.

OkComputer currently supports the following Rails versions:

• 3.2
• 4.1
• 4.2
• 5.0
