There are indeed commercial cli tools. One example I came across is sourceguardian[1], which is a command line tool to "protect" your PHP source code by encrypting it. This way you can put it on a server that is not controlled by yourself without risking rip-offs. However, it does not only contain a cli tool but also a free PHP module to load these encrypted PHP files as well as other tools. The licensing is pretty hard to get around, it uses a hardware id registered via online server, so you can't easily use the software on a device without having it properly licensed. Protecting your work will be a high amount of monetizing it. 1: https://www.sourceguardian.com/ https://www.sourceguardian.com/
