Overview
MockForge is a mocking framework supporting REST, gRPC, GraphQL, WebSocket, Kafka, MQTT and additional protocols. It enables developers to mock APIs locally or in the cloud with realistic data synthesis using template tokens and faker fields, and supports latency and failure injection to test retry and fallback behavior. The platform includes a modern admin UI for managing servers and metrics, record and replay functionality to capture and replay live traffic, and configuration-as-code workflows using OpenAPI specifications and YAML files. Teams can run the open-source CLI locally without an account, or use cloud hosting for collaboration and deployed mocks.
