AI-Powered API Mocking

Generate & Manage API Mocks Directly From Your LLM Client

Built for AI-first development workflows, the Virtualize MCP server integrates directly with your LLM client to generate and manage REST API mocks without coding or context switching. Parameterize responses and generate test data to create realistic, data-driven API behavior—all through agentic workflows.

Don’t Let Missing Dependencies Slow Down API Testing

When downstream systems aren’t ready, development stalls—even when your team may be ready to test, but the dependencies you rely on aren’t.

Parasoft Virtualize helps teams maintain momentum while dependent services catch up.

Fits Your Workflow

Use your preferred LLM tools and integrate Virtualize capabilities seamlessly into your existing development ecosystem.

Manage Mock APIs Directly in the Virtualize UI

Virtualize’s embedded AI assistant helps teams quickly generate and refine virtual services and API mocks using in-tool workflows.

The assistant offers step-by-step guidance, cuts setup time, and makes it easier to build and maintain API simulations—especially in collaborative or enterprise environments.
