Scalable Testing
Test more and test faster by decoupling from your API dependencies
API simulation with WireMock unblocks your testing strategy by removing flakey and expensive API dependencies
Simulate APIs to ship faster, test more often, cut costs, reduce bugs, and increase quality.
“WireMock Cloud delivers excellent value as it enables us to run our testing suite without relying on any external test data. It has become the backbone of our daily regression and sanity testing.”

Easier integration testing with mock APIs
Simulates interactions between services, ensuring smooth integration even when actual services are down
Mimics third-party APIs, enabling integration testing without relying on live endpoints
Introduce latency or errors, testing system resilience under real-world conditions
Get rid of expensive test environments
Reduce or remove entirely the cumbersome, expensive, and usually out of date sandboxes that your teams rely on for testing
Always up to date, realistic mock servers with stateful test sessions provide a better alternative - easier to maintain, lower cost, and less work for your developers to test with
Give your teams a world-class developer experience that enables better iteration, faster test cycles and more internal feedback


Inject complex failure states into your mocked APIs
Introduce chaos engineering with faults, delays and more
Control the percentage and distribution of failures to mimic real-world conditions
See how your app handles fail states that happen in the network layer: invalid HTTP, socket reset, socket close

Mock any 3rd party service for easy load testing
Easily mimic 3rd party services that impact load testing by recording traffic, importing a spec or using an existing template
More frequent load testing at less cost than traditional service virtualization tools means you can test more often and raise the quality bar for your applications
WireMock Cloud’s high performance environment means you can simulate your API dependencies during load testing without being impacted by the flakiness, unreliability or cost of the 3rd party APIs
“WireMock helps us catch bug escapes and identify defects before the product is released.”
