Mech
Supercharged Development Environments
Mech is a command-line tool for managing virtual machines, in the spirit of Vagrant but aimed at VMware (Fusion and Workstation) and free to use. Vagrant’s VMware support lived behind a paid plugin; mech does the same job, scriptably and for nothing. Spin a box up, snapshot it, share it, and tear it down, all from a small CLI.
I didn’t start this one. Kevin Chung wrote the original. I came in later and ended up the top contributor, with more than twice the commits, and drove its branding and the move into its own GitHub organization. It’s the cleanest example of a move I keep making: take a useful project, give it a real identity, stand up an org, and transfer it in so it can grow past any one person’s account. The same thing happened with SublimeLinter and SublimeCodeIntel.
