Smart

CATS is more than a fuzzing tool. Outside the typical fuzzing cases that generates random input, CATS also generates negative testing scenarios based on data types and structural constrains.

Fast

CATS is fast. Really fast. It automatically generates, runs and reports thousands of tests within minutes. No coding required.

Configurable

CATS has more than 30 configuration options. You can match or ignore HTTP response codes, response bodies, API paths, fuzzers, HTTP methods, fine tune reporting and so on.
