![Restler Fuzzer : API Fuzzing Tool For Automatically Testing Cloud Services](https://i1.wp.com/1.bp.blogspot.com/-kEHCXo_4n-M/X9ex4ja7bTI/AAAAAAAAIH0/C3G5GhUEqzAS3MH0kbfmQDUd4Y2CR457QCLcBGAsYHQ/s728/RESTler-arch%25281%2529.png?w=640&ssl=1)
RESTlerĀ is the first stateful REST API fuzzing tool for automatically testing cloud services through their REST APIs and finding security and reliability bugs in these services. For a given cloud service with an OpenAPI/Swagger specification, RESTler analyzes its entire specification, and then generates and executes tests that exercise the service through its REST API.
