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.
