API Mocking Tool

Develop and test APIs in parallel even when services are unavailable or rate limited. Build API mocks manually or automatically from live API traffic.

Embrace the API-first Approach

Leverage API mocking to kill dependencies in your API testing. Design and execute shift-left testing without delays.

Import and mass generate tests from Postman Collections, OpenAPI (OAS), Swagger, WSDLs, or RAML (Mulesoft)
Write smarter tests faster with our API testing tool (the Composer) for true consumer-driven tests
Automate test execution in any CI/CD pipeline, or schedule tests to run without a CI
Execute performance tests using existing web services functional tests
Turn any database into an API for data-driven API testing (read this DZone article for more info)

Create API Mocks with Ease

Build mocks manually, configure your gateway to send API calls to the platform, or use Bloodhound. The platform will capture API traffic and instantly create API mocks and tests with one click.

Easily Mock and Generate Tests

By recording API traffic, you can also automatically generate functional tests from these recorded APIs.

These functional tests can be easily reused as monitors and performance tests. Accelerate the delivery of new microservices while maintaining quality with API mocking.

Shift Testing Left

Our automation platform removes the pain from introducing API testing earlier in the development lifecycle. Mocking becomes a unified process that provides stakeholders with critical insights while APIs are still being developed. Other advantages include:

Avoid downtime by mocking unreliable internal APIs in a reliable staging environment
Save on development costs by mocking paid 3rd-party APIs
Isolate microservices to hunt difficult bugs down
Expedite API delivery by 40% or more with API Fortress

Standardize Mocking Across Teams

Give all team members access to mocking capabilities on a centralized platform. This allows you to enforce a standardized mocking and testing strategy that eliminates bottlenecks from API issues that are only found late in the development lifecycle.
