Thank you for your review

HaTTiP is an HTTP web services client.

  • HaTTiP has a simple, easy-to-use interface. Select a method, input the URL, set some headers, and you're set.
  • Request and response bodies can be displayed raw, or formatted and colorized for easy reading.
  • Save each request separately so they can be recalled and reused later.
  • Supports execution of a pre-processing script that can dynamically modify the outgoing request. Currently supports the use of Javascript, with more languages coming in a later release.

What's New

Note: Now requires OS X 10.11 or later

  • Clearing the request body no longer removes the Content-Type header.
  • Updated to a thicker, easier-to-read font
  • Now requires macOS 10.11 or higher
  • Complex content-type headers no longer confuse the body formatter.


  • OS X 10.11 or later
