Script-Manager is a tool for managing small utility scripts (as the name would suggest) although it will also work for native executables. It is written in C and uses SQLite to catalog the scripts in a searchable format. Script-Manager lets you set a name and description, both of which can be used to search.
CLI-JSON is a simple Python script for formating JSON from a command line interface. I created it specifically for formating the output from cURL via a pipe but it is also capable of reading JSON from a file or any other program that can pipe JSON into it. It is also capable of colouring the output. CLI-JSON is designed to be as simple as possible.
