WireMock Cloud helps developers, QAs, and AI agents ship quality code.
Deliver resilient software faster with AI-native API simulation

Stop depending on unreliable 3rd party APIs and sandboxes.

Build features faster with parallel development and API prototyping.

Eliminate costly test environments,  and excess API calls.

Building and testing with WireMock Cloud:

Simulate APIs, integrations, and environments

Integration-heavy environments don't have to be a blocker. Use the WireMock web UI, AI, or CLI to replace dependencies with realistic mocks - then switch back to the real APIs when you're ready to ship.

Get there faster with WireMock AI

WireMock fits nicely into your AI journey. Use your AI-powered IDEs to automatically detect API dependencies, create mock APIs from prompts, or generate realistic response data.

Runs anywhere you develop and test

Use WireMock Runner to simulate and record APIs locally. Collaborate on mocks and prototypes in the Cloud UI, and deploy anywhere - on your laptop, your cluster, or your CI/CD pipeline.

Light years beyond 
basic mocking.

Local development experience with the WireMock CLI

Import from OpenAPI or Swagger, or start with an API recording (local + web)

Enteprise-ready with SOC 2, SSO, RBAC, audit log, and Git sync

Stateful mocking,  response templating, body matching and dynamic response

Easily load test on-demand with any stress-testing criteria you need

Negative testing, inject chaos with delays, faults and more to prepare for the
rainy days in advance.

Generate test data or import your own
from CSVs and databases

Simulate REST, gRPC, GraphQL, and custom services

Prevent mock drift with contract testing and easy spec-to-mock verification
