Environment simulation infrastructure for agents and applications

Simulate the environments your agents and applications rely on, with high-fidelity, statefulness and production-realistic failures. Designed to evolve with your code as real systems change.

Dependencies break your SDLC

  • Third-party APIs and sandboxes are unreliable and never production-grade
  • Every team builds its own mocks. Nothing is shared or managed.
  • AI writes more code than anyone can verify, and agents can break production
Before: a CI pipeline, integration tests, a coding agent and AI evals each connect toward production, but every connection is broken; several production services are flagged with red and amber status lights.

Centrally owned environments that simulate everything agents and applications depend on

WireMock fully simulates production behavior for every team with little to no maintenance.

After: a simulated environment of the same nine services stands in front of production; all four workflows connect to it unbroken, and production sits behind, untouched.

A single source for shared simulations

Stateful simulations that update with every commit and run on laptops, in CI, and in your cluster.

Made for the AI SDLC

Create simulations as code, via a collaborative cloud UI, or agentically.

A cleanroom for agents

Agents run against sealed, trusted environments.

Agents and applications share environments, from laptop to CI

Velocity and reliability across every team

Devs get a full day back every week

A F100 company replaced hand-built mock environments with WireMock Cloud for its internal APIs and Azure integrations. Developer overhead dropped 20%.

Customer onboarding: 2–3 months to days or weeks

Coface replaced production-based testing with sandboxes that simulate the business logic and state behind its APIs.

Testing lifecycle: weeks to days or hours

Cuscal simulates client endpoints for its open banking platform, so daily regression and performance tests run without client data.

Devs trust WireMock

WireMock open source is the API simulation layer inside Spring Cloud Contract, Testcontainers, Spring Boot, Quarkus, and Micronaut. If your developers write Java, they’ve run it.

Stop waiting on systems you don’t control

We’ll show you what they look like as one shared, stateful environment applications and agents run against.
