Simulated environments for agents
WireMock Cloud helps humans and AIs deliver resilient software faster. Simulate APIs and microservices in prod-like conditions, without taxing your resources or budget.
Building and testing with WireMock Cloud:
Dependencies kill developer productivity. Keep shipping with WireMock Cloud.
Delivery is faster, environments have not kept up
Testing against dozens of 3rd party APIs and microservices is a struggle.
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
Test agents behavior while controlling everything from response to failure.
Legacy service virtualization does not fit today's SDLC
Teams are limited to basic mocking or clunky IT-centric tools.
Self-serve for every developer, tester, and AI agent
Put the power of simulation in everyone's hands: modern UI, 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
Prevent mock drift with contract testing and easy spec-to-mock verification
“WireMock gives us an extra day every week for every developer on the team.”
ROI? Check.
Less test environments to maintain. Less defects in production. More time to build. If you're looking for value, WireMock delivers.
