yapi is an API management platform designed to coordinate the development of RESTful APIs between frontend, backend, and quality assurance teams. It functions as a centralized system for documenting interface specifications, simulating server responses, and validating requests through a built-in testing client.
The platform features an API code generator that transforms interface specifications into typed request functions and data models across multiple programming languages. It also includes a mock server capable of generating synthetic responses using schema-based generators and rule-based simulation.
The system provides tools for interface documentation, automated API testing with response assertions, and an importer for migrating definitions from formats such as Postman and Swagger. User access to these resources is managed via a flat-hierarchy permission system.
