This gem is designed for use by Rails applications running on Heroku. For others, the better approach is to use a frontend server such as nginx or Apache. However, the Heroku Cedar stack is no longer fronted by a file server, and there is no automatic provision for gzipping responses. This gem activates Rack::Deflate for all requests. In addition, we serve up the gzipped versions of our precompiled assets, taking advantage of the higher compression ratio used during precompilation, and reducing CPU load at request time.

In version 5.0 the authors of the popular Ruby web server Puma chose to remove the daemonization support from Puma, because the code wasn't wall maintained, and because other and better options exist for production deployments. For example systemd, Docker/Kubernetes, Heroku, etc. Having said that, it was neat and often useful to daemonize Puma in development. This gem adds this support to Puma 5 & 6 (hopefully) without breaking anything in Puma itself. So, if you want to use the latest and greatest Puma 5+, but prefer to keep using built-in daemonization, this gem if for you.
