Agent Browser Gateway

Control Chrome with Codex, Claude Code, and more Agent Browser Gateway lets local AI coding agents work with your Chrome session while keeping browser access explicit, local, and under your control. By default, no tab is visible to an agent. You choose a tab from the extension popup, share it intentionally, and the local abg CLI can then read page context, capture screenshots, inspect console and network activity, and perform approved actions in that shared tab. For dedicated sandbox profiles, test machines, or disposable Chrome profiles, ABG also supports optional all-tabs mode. When enabled, Chrome asks for explicit permission to access all sites in that profile. This mode is off by default, can be revoked from the popup, and is intended only for environments where every open tab is deliberate agent context. ABG can: Share only the tab you explicitly authorize by default Read page content as text, Markdown, HTML, or JSON Capture screenshots and PDFs Inspect frames, dialogs, downloads, console logs, network activity, HAR files, cookies, and Web Storage Click, fill, paste, scroll, upload files, press keys, and wait for page state Inspect framework signals such as React trees and Web Vitals where available Record and replay local browser workflows Use local plugins for site-specific commands and transforms Run advanced JavaScript evaluation only when eval is enabled by the user. By default, each eval requires explicit approval and a local approval window showing the script; Trusted automation / AutoMode can skip that popup only for already-shared tabs and still writes audit logs. Use sandbox-only browser controls in isolated all-tabs profiles Privacy and control: No account required No ABG-operated cloud relay Extension-to-gateway communication stays on the local machine No analytics, advertising identifiers, or product telemetry No default access to all tabs Optional all-tabs access requires a local toggle and Chrome permission prompt Shared tabs and all-tabs mode can be revoked by the user Operations are written to a local audit log Write actions can require local approval before they run ABG requires the local Agent Browser Gateway app and CLI. The extension connects Chrome to that local gateway so Codex, Claude Code, and other local coding agents can use the browser context you choose, including your current login and browser state, without handing over the whole browser by default.
