# agent-browser-stealth
|
|
|
|
Stealth fork of [agent-browser](https://github.com/vercel-labs/agent-browser) — connects to your real Chrome, shares your login sessions, and is undetectable by anti-bot systems.
|
|
|
|
For basic usage, commands, and API reference, see the [upstream documentation](https://github.com/vercel-labs/agent-browser).
|
|
|
|
## Why this fork?
|
|
|
|
**agent-browser** launches a fresh browser with an empty profile. You need to log in again, and websites can detect it's automated.
|
|
|
|
**agent-browser-stealth** connects to your existing Chrome. Your cookies, sessions, and browser fingerprint are all real — because it IS your real browser.
|
|
|
|
| | agent-browser | agent-browser-stealth |
|
|
|---|---|---|
|
|
| Browser | Launches new Chrome | Connects to your Chrome |
|
|
| Login state | Empty, need to re-login | Your existing sessions |
|
|
| Fingerprint | Automation markers present | Your real fingerprint |
|
|
| User collaboration | Separate window | Same window, take over anytime |
|
|
| CAPTCHA | Agent stuck | You solve it, agent continues |
|
|
|
|
## Install
|
|
|
|
```bash
|
|
npm install -g agent-browser-stealth
|
|
```
|
|
|
|
### Install the AI agent skills
|
|
|
|
The repo ships SKILL.md files for Claude Code, Cursor, etc. Pull them into the current project with [skills.sh](https://skills.sh):
|
|
|
|
```bash
|
|
npx skills add leeguooooo/agent-browser-stealth
|
|
```
|
|
|
|
This drops `skills/agent-browser` (and the specialized `skill-data/{core,electron,slack,dogfood,agentcore,vercel-sandbox}`) into your project so your AI agent gets the right usage patterns and pre-approved bash permissions for `agent-browser`, `agent-browser-stealth`, and `abs`.
|
|
|
|
## Setup (one time)
|
|
|
|
Enable Chrome DevTools Protocol in your Chrome:
|
|
|
|
1. Open `chrome://inspect/#remote-debugging` in Chrome
|
|
2. Toggle the switch on
|
|
|
|
That's it. This setting persists across Chrome restarts.
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
# Connect to your Chrome and navigate
|
|
agent-browser open https://example.com
|
|
|
|
# Everything works through your logged-in browser
|
|
agent-browser click "Post"
|
|
agent-browser fill "Title" "Hello World"
|
|
agent-browser screenshot ./page.png
|
|
```
|
|
|
|
The agent operates in your Chrome — you'll see tabs opening, pages loading, clicks happening in real time. You can take over at any point (e.g. solve a CAPTCHA), then let the agent continue.
|
|
|
|
### Standalone mode
|
|
|
|
If you need a separate browser (CI, testing, etc.):
|
|
|
|
```bash
|
|
agent-browser --launch open https://example.com
|
|
```
|
|
|
|
In CI environments, standalone mode is used automatically.
|
|
|
|
## Anti-detection
|
|
|
|
When connected to your real Chrome, we inject **zero** JavaScript patches. Your browser's fingerprint is completely genuine.
|
|
|
|
The only thing we do is call `Emulation.setAutomationOverride` via CDP to set `navigator.webdriver = false` at the native Chrome level — undetectable by lie-detection systems like CreepJS.
|
|
|
|
**Test results (connected to real Chrome):**
|
|
|
|
| Test site | Result |
|
|
|---|---|
|
|
| [CreepJS](https://abrahamjuliot.github.io/creepjs/) | 0% stealth, 0% headless |
|
|
| [bot.sannysoft.com](https://bot.sannysoft.com) | All green |
|
|
| [Cloudflare Turnstile](https://nowsecure.nl) | Passed |
|
|
|
|
When using `--launch` mode (standalone browser), a full suite of 32 stealth patches is applied for headless Chrome.
|
|
|
|
## Differences from upstream
|
|
|
|
Based on [agent-browser v0.27.0](https://github.com/vercel-labs/agent-browser). Changes:
|
|
|
|
- **Auto-connect is default** — `agent-browser open <url>` connects to your Chrome instead of launching a new one
|
|
- **CDP-native stealth** — `Emulation.setAutomationOverride` instead of JS patches
|
|
- **Dual stealth mode** — zero patches for real Chrome, full patches for `--launch` mode
|
|
- **`--launch` / `--new` flag** — explicitly start a standalone browser
|
|
- **CI auto-detection** — standalone mode when `CI` env var is set
|
|
|
|
All upstream features (commands, snapshots, screenshots, recordings, tabs, sessions, etc.) work the same. See the [upstream repo](https://github.com/vercel-labs/agent-browser) for full documentation.
