Chrome CDP

Lightweight Chrome DevTools Protocol CLI. Connects directly via WebSocket — no Puppeteer, works with 100+ tabs, instant connection. Uses a persistent per-tab daemon so Chrome's "Allow debugging" modal fires only once.

Prerequisites

• Chrome with remote debugging enabled: open chrome://inspect/#remote-debugging and toggle the switch
• Python 3.10+ with websockets library

Commands

All commands use python -m chrome_cdp. The <target> is a unique targetId prefix from list; copy the full prefix shown in the list output (for example 6BE827FA). The CLI rejects ambiguous prefixes.
