God of all Browsers

A 100x smarter browser automation CLI that mimics human behavior using a native stateful Chromium instance. It supports multi-tab management, bypasses bot detection, auto-closes popups, and preserves cookies permanently.

A stateful, multi-tab Puppeteer skill designed to help AI agents automate heavily protected websites the exact same way a human does.

It solves three critical AI problems:

1. Tabs & Statefulness: It launches a single background browser that stays open. Navigations, clicks that open new tabs, and cookies are remembered across multiple commands!
2. Vision Abstraction: AI cannot "see" coordinates well, so snapshot maps the DOM, assigns a [tag] ID to every visible button/input, and takes a screenshot. The AI just says "Click tag [15]."
3. Bot Evasion: Uses headless: false, custom user agents, removed webdriver footprints, and canvas spoofing.

Important Setup: Ensure the Chromium path is correct (C:\Program Files\Google\Chrome\Application\chrome.exe for Win or /usr/bin/chromium for Linux) and puppeteer-core is installed.

🚀 COMMANDS & WORKFLOW

1. Start the Browser (Required First Step)

Launch the browser in the background. It will use a persistent chrome_profile directory so you NEVER lose login sessions.

bash

# Standard mode (Recommended for debugging)
node browser.js start

# Headless mode (Faster, silent background)
# Note: Automatically enabled if running in Termux.
node browser.js start --headless

2. Take a Snapshot (And auto-close popups)

This is your "eyes". Run this before any interaction to get the active window's current state and a list of clickable [tag] IDs.

bash

# If navigating somewhere new:
node browser.js snapshot --url "https://www.google.com"

# If already on the page (refresh DOM):
node browser.js snapshot

Wait for this command to output the JSON array of tags. It will also automatically click away annoying Chatbot/Notification popups.

3. Click or Type (Like a human)

Use the tags captured during the snapshot.

bash

# Click a button or link (e.g. tag [24])
node browser.js click --tag "[24]"

# Type into an input box (e.g. tag [5])
node browser.js type --tag "[5]" --text "MERN Stack Developer"

# Press a specific keyboard key (Default: Enter)
node browser.js press --key "Enter"

4. Reading & Content Extraction

Extract text content from any element using tags or CSS selectors.

bash

# Read visible text from a specific tag
node browser.js read --tag "[12]"

# Read content of a specific CSS selector (e.g. the main article)
node browser.js read --selector "article.main-content"

# Deep-expand hidden content (clicks Read More/Show All buttons automatically)
node browser.js expand

5. Tab Management

Many sites open clicked links in a new tab! If your click command opens a new tab, the CLI will automatically say: ⚠️ A NEW TAB WAS OPENED!! Automatically switched context to Tab [1].

You can manually manage tabs using:

bash

# List all currently open tabs
node browser.js check-tabs

# Switch to a specific tab index (e.g. going back to the search page: tab 0)
node browser.js switch-tab --index 0

# Just check the very current URL you are viewing:
node browser.js check-url

5. Find Tags (Accurate Filtered Search)

Use this to filter elements by keywords instead of reading a massive snapshot. It can search live on the current page or in a previously saved JSON file.

bash

# Search live for "Apply" or "Success" buttons
node browser.js find --query "apply,success"

# Search within a specific saved snapshot file (e.g., to verify output)
node browser.js find --file "snapshot.json" --query "applied,successfully"

6. Refresh Page

Manually reload the current tab. Useful for status updates.

bash

node browser.js refresh

7. Scrape Meta Tags (SEO/OpenGraph)

Extract hidden page data like Title, Description, and Social Media tags.

bash

node browser.js scrap-meta

8. Dynamic Evolution (Eval)

Execute custom JavaScript logic directly in the browser context. Note: For security, the --force flag is required. Supports both inline code and script files.

bash

# Execute inline code (Requires --force)
node browser.js eval --code "return { links: document.querySelectorAll('a').length }" --force

# Execute from a file (Requires --force)
node browser.js eval --file "custom_script.js" --force

9. Google Search (Direct Extraction)

Get the top 5 organic search results (Titles, Links, Snippets) in a single command. Extremely fast and agent-friendly.

bash

node browser.js google --query "Mathanraj Murugesan"

10. Session & Learning

Manage your login state and keep track of automation failures for self-correction.

bash

# Save current cookies to session.json (persists across runs)
node browser.js save-session

# Check if the page requires login or if the user already logged in
node browser.js auth-status

# Log a failure and a lesson learned for AI self-correction
node browser.js log-learning --failed "Selector [12] was hidden" --fixed "Used [expand] first" --lessons "Always try expanding content before reading"

11. Stop the Browser

Clean up resources when the task is entirely finished.

bash

node browser.js stop

🧠 AI STRATEGY (HOW TO USE)

1. Run start.
2. Run snapshot --url "[TARGET]".
3. Check auth-status if the page is restricted. Use save-session after manual/automated login.
4. Analyze the output tags. Think step-by-step. Does the page require a search? Does it require clicking an 'Apply' button?
5. Run click or type on the specific [tag].
6. READ THE CLICK OUTPUT CAREFULLY! Did it say a new tab opened? If so, your next snapshot will read from that tab.
7. Run snapshot again WITHOUT a URL to read the new page/modal that loaded.
8. Repeat until the task is complete. If you need to return to the search results, run check-tabs and switch-tab --index 0.
9. If you encounter a bug (e.g., selector not found), use log-learning to record the fix for future runs.
10. If you need to run custom JS, use eval with the --force flag.
11. Once finished, run stop.

10. Common Extraction Patterns (USE EVAL)

When you need to get actual data (not just see the page), use the eval command with these patterns:

Google Search Results:

bash

node browser.js eval --force --code "return Array.from(document.querySelectorAll('div.g')).slice(0,5).map(g => ({ title: g.querySelector('h3')?.innerText, link: g.querySelector('a')?.href }))"

LinkedIn Profile (Basic):

bash

node browser.js eval --force --code "return { name: document.querySelector('.text-heading-xlarge')?.innerText, title: document.querySelector('.text-body-medium')?.innerText }"

General Link Scraper:

bash

node browser.js eval --force --code "return Array.from(document.querySelectorAll('a')).map(a => ({ text: a.innerText, url: a.href })).filter(a => a.url.startsWith('http'))"

11. Robust Automation Workflow (Multi-Tab & State)

Follow this professional flow for complex, multi-stage automation tasks:

1. Initialize: Run start to launch the persistent browser instance.
2. Navigation & Auth:
   • Run snapshot --url "[TARGET]" to land on the page.
   • Run auth-status to check if a login is required.
   • If you perform a manual/auto login, run save-session to persist the state.
3. Clean & Expand:
   • Always run expand before deep scanning. This removes popups and reveals hidden content that might be missing from the DOM.
4. Action Loop:
   • Run snapshot (without URL) to get the latest [tag] list.
   • Perform interactions using click, type, or press.
   • Pro Tip: If a click result is ambiguous, run check-url to see if the page changed.
5. Multi-Tab Handling:
   • If the terminal warns ⚠️ A NEW TAB WAS OPENED, run check-tabs.
   • Note the index of the new tab (e.g., [1]) and run switch-tab --index 1.
   • Every snapshot and command thereafter will target this new tab.
6. Extraction:
   • Use read --tag "[#]" for simple text.
   • Use eval for complex data structures (arrays of objects, etc.).
7. Recovery & Learning:
   • If a command fails, use log-learning --failed "..." --fixed "..." to document the solution for the AI's internal memory.
8. Teardown: Run stop only when the entire job (across all domains) is finished.
