UglifyJS vs yamlfmt
Both stand on code formatting tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APILinuxSelf-hosted
Choose UglifyJS if you need a free JavaScript toolkit with command-line and API options, source maps and AST utilities. Look elsewhere if your syntax needs exceed its supported features without transpilation, or if you need the defaults to target the compatibility environments it excludes.
