All the features you need for powerful, flexible API mocking

Built on WireMock, the #1 open-source API mocking framework. WireMock Cloud offers a hosted experience including a self-service UI, enterprise support, and unlimited scale.

Manual and automated testing

Craft your simulation using the friendly, no-code UI or go fully automated with the 100% WireMock-compatible API.

Swagger support

Import your Swagger definitions to generate mock APIs automatically, directly with Swaggerhub via webhooks.

Error and Load Testing

Test your app to destruction with high load or by injecting delays, dropped connections, drip-drip responses and corrupt HTTP payloads.

Record and playback

Capture traffic to another API, then play it back from WireMock Cloud.

Response templating

Dynamically render responses using the templating language.

Stateful scenarios

Simulate real world application behavior with dynamic test states that let you easily simulate complex interactions and scenarios.
