WireMock Cloud helps humans and AIs deliver resilient software faster. Simulate APIs and microservices in prod-like conditions, without taxing your resources or budget.

Trusted at enterprise scale:

Dependencies kill developer productivity. Keep shipping with WireMock Cloud.

Without wiremock cloud

Delivery is faster, environments have not kept up

Developers struggle to test features that interact with dozens of 3rd party APIs and microservices.

With Wiremock Cloud

Scale testing while controlling costs

Test against stateful replicas of your dependencies. No sprawl, no rate limits. No waiting for other teams.

AI creates unpredictable code

Non-deterministic LLMs can risk stability and security. Teams need a virtual sandbox to test AI outputs.

Add control with deterministic simulation

Run your agents in realistic simulation where you control everything from response behavior to failure scenarios.

Legacy service virtualization does not fit today's SDLC

Teams are limited to basic mocking or clunky desktop-centric tools built for centralized IT teams.

Self-serve for every developer, tester, and AI agent

WireMock Cloud puts the power of simulation in everyone's hands with modern UI, cloud APIs, and AI.

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
