Network Control for End-to-End Web Testing
summary
Plugin Cypress Magic Backend records requests and responses to JSON, replays them to intercept XHRs and cut a 6s test down to roughly 600ms — a 10x speedup claim — and adds an inspect mode that compares timing and object schema to the recorded run, flagging slow calls or missing fields. It supports remote storage of recordings, a Cypress watch-and-reload hook for instant reruns when static files change, exposes AI-ready prompts for LLM debugging, and ships under a Polyform small business license.
