RESTler is the first stateful REST API fuzzing tool, automatically testing cloud services through their REST APIs to find security and reliability bugs. It infers producer-consumer dependencies from OpenAPI specifications and generates request sequences that explore deeper service states.
Use cases
- fuzz a rest api for security bugs
- automatically test cloud service endpoints from an openapi spec
- find crashes and reliability bugs in rest apis
- generate stateful api request sequences for testing
- regression testing for rest apis
- check security properties of api endpoints
When to choose
- you have an OpenAPI/Swagger specification for a REST API you want to test
- you need automated discovery of security and reliability bugs in cloud services
- you want stateful fuzzing that explores multi-request sequences
- you need a research-backed fuzzing tool with multiple test generation strategies
When to avoid
- your service has no OpenAPI specification available
- you need to test GraphQL, gRPC, or non-REST interfaces
- you want simple load or performance testing rather than bug finding
- you need a GUI-driven manual API testing tool like Postman
