Chrome DevTools
Chrome DevTools is a set of web development and debugging tools built directly into the Google Chrome browser, requiring no separate installation. Core capabilities include real-time HTML and CSS editing with element inspection, JavaScript breakpoint debugging and performance profiling, network request monitoring, memory and performance analysis, and code coverage reporting. It is widely used in front-end development, performance optimization, and issue investigation, and serves as an essential tool for web developers.
Core Facts
Lighthouse is an open-source automated tool developed by Google, built into Chrome DevTools, providing multi-dimensional web quality scoring including accessibility.
Agent DevTools draws inspiration from Browser DevTools, allowing developers to inspect an AI Agent's internal operations similarly to how Chrome DevTools inspects page elements and network requests
Timeline (last 90 days)
Chrome DevTools' support for anchor positioning is not yet complete, and the team is working on improvements.
The Network panel in Chrome DevTools has officially retired the "Replay XHR" feature, replacing it with a new feature called "Resend".
Resend also provides an "Edit and Resend as Fetch" option, which can convert the request into Fetch code to be modified in the Console panel before execution.
Copy as Fetch is a right-click menu feature long provided by the Chrome DevTools Network panel, which can convert a selected network request into equivalent JavaScript fetch() code.
The Resend feature allows developers to select any request in the Network panel and resend it immediately with a click, while preserving all Header, Cookie, and Payload information of the original request.
The Replay XHR feature existed for nearly a decade and was mainly used to resend captured XHR requests.
The two browser-type servers, Playwright and Chrome DevTools, can see all pages they open, including any websites the user is logged into.
The Chrome DevTools MCP server lets Claude inspect and debug pages, and by default collects usage statistics for Google, though users can manually opt out.
A Chrome DevTools MCP server may burn approximately 18,000 tokens before executing its first meaningful action.
The live binding feature of the Scope panel in Chrome DevTools is not a bug, but it can easily create the illusion for reverse engineering beginners that the signature was generated at an earlier point.
