Another free, open source, command-line tool. Whereas curl is ideal for scripting, HTTPie is optimized for interactive use. It has a very user-friendly UI, colorized and formatted output, and other features that make it really nice to use. -
A free, cross-platform app that makes it easy to experiment with APIs in a friendly interface. -
