Install
About two minutes. One line installs Browsentic Bridge on your computer, opens the extension’s store page in your browser, and shows a one-time code to pair the two.
On macOS
curl -fsSL https://browsentic.com/install.sh | sh
On Windows, in PowerShell (experimental)
irm https://browsentic.com/install.ps1 | iex
Anywhere, with Node.js 20 or newer
npx browsentic@latest setup
Setup asks which browser you use and opens the extension’s store page there. Press Add, click Browsentic in the toolbar and enter the code setup shows, once.
Chrome, Edge, Brave, Arc, Vivaldi or Opera, or Firefox 140 or newer.
For the command line only. The apps bring their own.
Claude Code, Codex, Antigravity, Mistral Vibe, Grok Build, Cursor CLI, Qwen Code or OpenCode. Nothing to paste into Browsentic.
Command line
Four steps, the last one optional. Press a step to watch it again.
It starts Browsentic Bridge, checks your agent CLI, asks which browser to set up and opens the extension’s store page there. Nothing to clone or build.
Available in the Chrome Web Store
Available on Edge Add-ons
Firefox add-on, signed by Mozilla
npx browsentic@latest setup
Press Add to Chrome on the page setup opened. Brave, Arc, Vivaldi and Opera use the same page; Edge opens its own Edge Add-ons listing, where you press Get. It updates itself from then on.
On Firefox, run npx browsentic@latest setup --browser firefox and accept both prompts for the signed add-on it opens. It updates itself.
Click Browsentic in the toolbar, enter the code setup printed and press Connect. A code works once, for ten minutes; this command prints a new one.
npx browsentic pair
The side panel works without this. It gives Claude Code the same browser; Codex, Cursor and Zed work too.
claude mcp add browsentic -- browsentic mcp

It downloads the latest release for your computer, installs the app and opens it.
It installs whatever is missing, Node.js and Browsentic Bridge, and offers Claude Code if no agent is ready.
Every browser gets a row. Its button opens the store page in that browser and shows the pairing code to enter, once.
Check
browsentic status reports every part. A working install looks like this.
EXTENSION_OFFLINE
No browser is paired or open. Click Browsentic in the toolbar and enter a new pairing code.
AGENT_MISSING
The agent CLI is not on the Bridge’s PATH. Set agents.<name>.bin to its full path.
TAB_UNREACHABLE
The extension has not reached that tab yet. Reload the page.
Later
npx browsentic@latest update
Updates Browsentic Bridge and restarts it; the browser stays paired. The extension updates itself from its store, and the two do not have to be the same version. The apps offer each update on their Overview tab.
npx browsentic uninstall
Stops the Bridge and removes its folders, after showing you the plan. Remove the extension from your browser yourself: right-click its icon, then Remove.
Questions
No. Browsentic starts the agent CLI you already signed in to, such as Claude Code or Codex, as you. There is nothing to paste into Browsentic.
The Chrome Web Store for Chrome, Brave, Arc, Vivaldi and Opera, and Edge Add-ons for Edge. Setup opens the right one for you: press Add to Chrome, or Get in Edge, and it updates itself from then on. Firefox gets a Mozilla-signed add-on from each release, which updates itself too. A browser that cannot reach a store can load it from a folder: npx browsentic@latest setup --unpacked.
The half of Browsentic that runs on your computer. An extension cannot start a program on its own, so the Bridge does: it listens on your own machine only, runs the agent CLI you chose, and keeps everything local. The Mac and Windows apps are the Bridge in a window; npx browsentic@latest setup is the same thing from a terminal.
Run npx browsentic pair for a new one, or press Get a pairing code in the app. Each code works once and lasts ten minutes. Once paired, the browser keeps a session key and never needs a code again, even after an update.
Yes. Run npx browsentic@latest setup with Node.js 20 or newer: it opens the extension on the Chrome Web Store, or the Firefox add-on, in the browser you pick. The macOS and Windows apps are optional: everything they do, the command does too.
Free and open source under Apache 2.0, with no API key, subscription or account. One line installs Browsentic Bridge and opens the extension’s store page. Nothing connects until you pair the two.
