fpm vs. packagecloud.io vs. aptly

It helps you build packages quickly and easily (Packages like RPM and DEB formats). FUNDAMENTAL PRINCIPLE: IF FPM IS NOT HELPING YOU MAKE PACKAGES EASILY, THEN THERE IS A BUG IN FPM.

Install packages with apt-get install, yum install or gem install exactly like you do now. No additional software required. Track, analyze and control access to your packages. Programmatically issue and revoke credentials with our API.

aptly is a swiss army knife for Debian repository management: it allows you to mirror remote repositories, manage local package repositories, take snapshots, pull new versions of packages along with dependencies, publish as Debian repository.
