Codex can now use the Chrome DevTools Protocol (CDP) in the browser to inspect console logs, runtime errors, local storage, applied styling, network traffic, and performance profiles when working on web applications. In this demo, Codex investigates a slow chat application by profiling interactions and inspecting network requests, then fixes issues and supports changes with clear metrics. To use this feature, enable developer mode in your Codex app's browser settings and approve CDP access when Codex begins inspecting a website.
