Tab Steer

Hand your coding agent a tab, not your browser. Lets a local command-line tool control only the tabs and sites you share.

Tab Steer lets AI coding agents work in your real, logged-in browser, limited to the tabs and sites you choose. It pairs this extension with a small open-source command-line tool on your computer. Any agent that can run a shell command (Claude Code, Antigravity, Codex, Cursor, or a script) can then read a page as compact Markdown, click, type, wait and take screenshots. Typical uses: checking the app you are building on localhost, reading pages behind your login, reproducing a bug step by step, and routine chores in web dashboards. YOU STAY IN CONTROL - Shared tabs only. The agent acts only on tabs in the "Tab Steer" tab group. Click "Share this tab" in the toolbar popup, or drag a tab into the group. Drag it out to stop. - Allowed sites only. Tab Steer asks Chrome for site access once, when you click "Turn on". It then works only on sites you allow, and sharing a tab allows its site. Remove a site at any time. - See everything. The Activity side panel lists every action the agent takes, live. Typed text is never logged. - One-click pause. Every command is refused until you resume. - Passwords stay hidden. Values of password, payment and one-time-code fields are never returned. - No arbitrary code. There is no command to run scripts in your pages. PRIVATE BY DESIGN - Nothing is collected and nothing is sent to us or to any third party. - The command-line tool talks to the extension over a private connection ng listens on the network. REQUIRES A COMPANION PROGRAM Tab Steer does nothing on its own. After installing, a welcome page walks you through installing the free companion tool (macOS and Linux, Node.js 18 or newer).
