Debug web apps with browser use in Codex

Author: OpenAI - Bewertung: 23x - Views:303

Codex can now use the Chrome DevTools Protocol (CDP) in Browser Use to inspect console logs, runtime errors, local storage, applied styling, network traffic, and performance profiles while working on web applications.



In this demo, Codex investigates a slow chat app by profiling interactions and inspecting network requests, then fixes the issues and supports the changes with clear measurements.



To use this functionality, enable Developer mode in the Browser settings of your Codex app and approve CDP access when Codex starts inspecting a website.
