## Service Virtualization: Test in Isolation with Realistic API Responses

*   Eliminate flaky tests caused by external dependencies
    
*   Test edge cases and error scenarios safely
    
*   Reduce costs of maintaining staging environments

## Self-service backends when you need them

More likely than not, your software is integrated with a bevy of other APIs—shipping, payment, messaging, and more. With Speedscale, auto-generate sophisticated mocks of third party and internal APIs, modeled after real Traffic Context.

### Real Traffic Mocks

Generate mocks from actual Traffic Context, not synthetic data.

### Minutes to Setup

Provision API, database, and cloud service mocks in minutes, not days.

### Cost Effective

Eliminate expensive staging environments and third-party API costs.

## Mock Any Service Type

### REST APIs

Mock HTTP/HTTPS REST services with realistic responses.

### gRPC Services

Support for gRPC services with streaming and unary calls.

### Databases

Mock database connections and responses for isolation testing.

### Cloud Services

Simulate cloud services like S3, DynamoDB, BigQuery, etc..

## Common Use Cases

### Third-Party API Mocking

Mock external APIs like payment processors, shipping providers, or authentication services. Test integration scenarios without hitting live endpoints or incurring costs.

*   Payment gateway testing
*   Social media API integration
*   Shipping and logistics APIs

### Internal Service Mocking

Mock internal microservices and databases to enable isolated testing. Perfect for teams working on different services that need to test independently.

*   Database connection mocking
*   Microservice dependencies
*   Legacy system integration

## Ready to virtualize your services?

Start creating realistic service mocks from actual traffic patterns to accelerate your development workflow.
