JSONPlaceholder 是一个 REST API 模拟服务器和 JSON 模拟服务，提供托管的前端开发沙箱。它作为一个伪后端，返回预定义的 JSON 响应，以模拟用于开发和测试的 REST API。 该服务支持跨源资源共享（CORS），允许从不同的浏览器域测试 API 集成。它能够模拟 CRUD 操作并检索模拟数据，而无需实时数据库。 该系统将 URL 模式映射到静态的基于 JSON 的数据存储，并以无状态方式处理请求。它包括用于查询参数过滤和嵌套资源映射的功能，以模拟一对多关系数据结构。

moco is a multi-protocol mock server and programmable API stub used to simulate HTTP, REST, WebSocket, and Server-Sent Events endpoints. It enables the creation of fake backend services to facilitate development and integration testing without requiring a live server. The project distinguishes itself through its ability to act as a network traffic replay tool, capturing real request-response pairs via a proxy and playing them back locally. It also supports bidirectional communication simulations, including WebSocket server simulation and SSE stream simulation with configurable delivery delays

proxy.py is a lightweight, dependency-free HTTP and reverse proxy framework built in Python that handles network traffic through asynchronous event loops and multi-core connection distribution. It acts as a customizable proxy server and embedded web server, allowing developers to inspect, route, and modify web traffic programmatically or via command-line execution wrappers. The platform provides in-flight TLS interception and traffic decryption using generated root certificates, alongside modular extension hooks that support custom dashboard interfaces, request handling plugins, and REST API
