WireMmock Cloud
Simulate APIs and integrations in WireMock Cloud to test applications and collaborate in controlled environments.
About WireMmock Cloud
WireMock Cloud is environment simulation and API mocking infrastructure for applications and AI agents. It simulates the systems an application or agent depends on, including stateful behavior and production-realistic failures such as latency, errors and outages, so tests and development do not wait on third-party APIs or sandboxes. Simulations can be created as code, through a collaborative cloud UI, or agentically, and are described as updating with every commit.
Key features
- Stateful API simulations that update with each commit
- Create simulations as code, via cloud UI, or agentically
- Simulate latency, errors, outages and edge cases on demand
- Build against an API from its spec before it exists
- Simulations run on laptops, in CI, and in clusters
- Cleanroom execution where agent calls are simulated, not production
Best for: Development and platform teams that need shared, maintainable simulations of third-party APIs and dependencies for application and agent testing.
Good for
- Open-source WireMock is the simulation layer inside Spring Cloud Contract, Testcontainers, Spring Boot, Quarkus and Micronaut
- Vendor-published case studies describe reduced developer overhead and shorter onboarding and testing cycles
- Shared simulations replace per-team hand-built mocks, giving teams one managed source
Watch out for
- No pricing information is published on the homepage
- Web-only and not open source, unlike the separate WireMock open-source project
- The performance and time-saving figures come from vendor-published case studies

WireMmock Cloud FAQ
How does WireMock Cloud relate to open-source WireMock?
Open-source WireMock is the API simulation layer used inside Spring Cloud Contract, Testcontainers, Spring Boot, Quarkus and Micronaut.
Where can the simulations run?
The site states that simulations run on laptops, in CI, and in your cluster.
Can agents be tested without their calls reaching production?
Agents can run against sealed, simulated environments, and the site says nothing an agent does reaches production if you do not want it to.
