Features

• API Mocking - Provides a multi-protocol mock server to simulate HTTP, gRPC, and WebSocket endpoints for client testing.
• OpenAPI Mock Generators - Automatically generates mock API responses and expectations from OpenAPI or Swagger specification files.
• AI and LLM Testing - Simulates AI chat completions and streaming responses to test LLM workflows without external providers.
• API Interception Proxies - Intercepts and records live network traffic to verify request patterns and assert correct API call sequences.
• Request Matching Engines - Maps incoming network requests to predefined responses using metadata, body content, or header patterns.
• API Response Simulators - Matches incoming requests on metadata or bodies to return configured responses across multiple protocols.
• LLM Response Simulators - Provides a mocking interface for testing LLM integrations by simulating chat completion and streaming responses.
• Multi-Protocol Proxies - Provides a proxy layer that handles communication across HTTP, gRPC, and WebSockets.
• API Behavior Definitions - Allows defining expected requests and corresponding responses for HTTP, gRPC, and WebSocket APIs.
• LLM Behavior Simulators - Simulates chat completion interfaces and streaming responses to test large language model integrations.
• HTTP Mock Servers - Simulates HTTP, gRPC, and WebSocket endpoints to test client applications without relying on live backend services.
• Network Failure Simulations - Simulates network-level errors like timeouts and dropped connections to verify application resilience.
• API Contract Validation - Validates that clients correctly implement an OpenAPI specification by simulating expected request/response patterns.
• OpenAPI Specification Imports - Automatically generates request expectations and response behaviors from OpenAPI and Swagger specification files.
• OpenAPI Specification Parsers - Parses OpenAPI specifications to translate them into automated request expectations and responses.
• Real-Time Traffic Dashboards - Provides a real-time web dashboard to visualize incoming HTTP requests and server logs for live inspection.
• Traffic Recorders - Captures and stores live HTTP traffic for subsequent analysis or playback in testing scenarios.
• Network Traffic Analyzers - Intercepts, records, and modifies live API requests and responses to analyze data flow and debug traffic.
• Traffic Interceptors - Captures and alters live network packets between a client and a server to simulate network conditions.
• Traffic Interception and Modification - Intercepts and actively alters live network requests and responses in transit to analyze or modify data.
• Scripted Mock Responses - Generates flexible, dynamic responses using scripts and templates to avoid static values during testing.
• Request Sequence Verification - Asserts that specific requests reached the server in the correct order and with the expected frequency.
• Stateful Request Tracking - Tracks the sequence and frequency of incoming requests to validate the ordering of client-side API calls.
• Response Templating - Produces dynamic content by interpolating variables or executing scripts within response bodies at runtime.
• Mocking Tools - Solution for mocking HTTP/HTTPS services.
