About API Mock Servers
Mock servers enable frontend development and testing without a real backend. They return predefined responses for API calls, letting teams work in parallel. This tool generates Express.js mock server code you can run locally with node app.js after installing express. Ideal for prototyping, contract testing, and demo environments.
