Every agent in your Chrome, not just Claude

Claude in Chrome gives one agent your browser, on a paid plan, in a window you share with it. Tabhand gives every agent you use tabs of its own in your signed-in Chrome, in the background, for free.

Why people switch

Every agent, one extension

Claude in Chrome works with Claude. OpenAI’s extension works with ChatGPT and Codex. Each AI company’s extension serves its own agent, so two agents would mean two extensions and two subscriptions.

Tabhand serves all of them, from one setup command: Claude Code, Codex, Cursor, OpenCode, Gemini CLI and 14 more. Run three at once and each gets its own tab group, color and cursor, and none can touch another’s tabs.

Free, with any Claude plan or none

Claude in Chrome needs Pro, Max, Team or Enterprise, and Claude Code has to be signed in with /login. On an API key, Claude Code keeps it switched off, even when you pass --chrome. Through Amazon Bedrock, Google Cloud or Microsoft Foundry, it isn’t available at all.

Tabhand doesn’t ask how you pay for your agent. No plan, no account, no key.

You keep your browser

Anthropic’s docs say Claude in Chrome’s actions “run in a visible Chrome window in real time”.

Tabhand’s agents work in background tabs, muted. Chrome never jumps to the front, and the tab you’re in stays put, so you can keep writing while your agent works through your dashboards in tabs behind you.

You type in Google Docs while Claude works in its own tabs behind you

Work and personal, kept apart

Signed in to work in one Chrome profile and personal in another? Tabhand works in each of them, by name. Tell your agent “use my work profile” and it does, and it stays there.

Is it safe to give an agent my Chrome?

Tabhand is built so you don’t have to take that on trust:

Agents only reach their own tabs. An agent can use the tabs it opened and pages those open. Your tabs, and other agents’ tabs, are off limits.
One click stops everything. The Tabhand icon in Chrome’s toolbar pauses every agent at once.
Agents check with you first. Tabhand tells them to ask before sending messages, posting, buying, deleting or changing settings.
Nothing leaves your Mac. No servers, no accounts, no telemetry. The code is on GitHub for anyone to read.

Setup adds Tabhand to the agents on your Mac and opens the Chrome Web Store for the extension. Restart your agent and ask it to open a page. The docs have the rest.
