Installation

Quick install (macOS / Linux)

curl -fsSL https://raw.githubusercontent.com/billy-enrizky/openbrowser-ai/main/install.sh | sh

Quick install (Windows PowerShell)

irm https://raw.githubusercontent.com/billy-enrizky/openbrowser-ai/main/install.ps1 | iex

Detects uv, pipx, or pip and installs OpenBrowser automatically.

Install to ~/.local/bin without sudo:

curl -fsSL https://raw.githubusercontent.com/billy-enrizky/openbrowser-ai/main/install.sh | sh -s -- --local

Homebrew (macOS / Linux)

brew tap billy-enrizky/openbrowser
brew install openbrowser-ai

pip

pip install openbrowser-ai

uv (recommended)

uv pip install openbrowser-ai

uvx (zero install)

Run directly without installing -- uvx downloads and caches the package automatically:

# MCP server mode
uvx openbrowser-ai --mcp

# CLI daemon mode
uvx openbrowser-ai -c "await navigate('https://example.com')"

pipx

pipx install openbrowser-ai

From source

git clone https://github.com/billy-enrizky/openbrowser-ai.git
cd openbrowser-ai
uv pip install -e ".[agent]"

Optional Dependencies

pip install openbrowser-ai[agent]      # LLM agent support (langgraph, langchain, litellm)
pip install openbrowser-ai[all]        # All LLM providers
pip install openbrowser-ai[anthropic]  # Anthropic Claude
pip install openbrowser-ai[groq]       # Groq
pip install openbrowser-ai[ollama]     # Ollama (local models)
pip install openbrowser-ai[aws]        # AWS Bedrock
pip install openbrowser-ai[azure]      # Azure OpenAI
pip install openbrowser-ai[video]      # Video recording support

No separate browser install needed. OpenBrowser auto-detects any installed Chromium-based browser (Chrome, Edge, Brave, Chromium) and uses it directly. If none is found and uvx is available, Chromium is installed automatically on first run. To pre-install manually (requires uvx): openbrowser-ai install

Quick Start

Basic Usage

import asyncio
from openbrowser import CodeAgent, ChatGoogle

async def main():
    agent = CodeAgent(
        task="Go to google.com and search for 'Python tutorials'",
        llm=ChatGoogle(model="gemini-3-flash"),
    )

    result = await agent.run()
    print(f"Result: {result}")

asyncio.run(main())

With Different LLM Providers

from openbrowser import CodeAgent, ChatOpenAI, ChatAnthropic, ChatGoogle

# OpenAI
agent = CodeAgent(task="...", llm=ChatOpenAI(model="gpt-5.2"))

# Anthropic
agent = CodeAgent(task="...", llm=ChatAnthropic(model="claude-sonnet-4-6"))

# Google Gemini
agent = CodeAgent(task="...", llm=ChatGoogle(model="gemini-3-flash"))

Using Browser Session Directly

import asyncio
from openbrowser import BrowserSession, BrowserProfile

async def main():
    profile = BrowserProfile(
        headless=True,
        viewport_width=1920,
        viewport_height=1080,
    )
    
    session = BrowserSession(browser_profile=profile)
    await session.start()
    
    await session.navigate_to("https://example.com")
    screenshot = await session.screenshot()
    
    await session.stop()

openbrowser-ai -c "await navigate('https://example.com')"
openbrowser-ai -c "print(await evaluate('document.title'))"

The daemon starts automatically on first use and persists variables across calls.

For OpenClaw plugin documentation, see docs.openclaw.ai/tools/plugin.

MCP Server

OpenBrowser includes an MCP (Model Context Protocol) server that exposes browser automation as tools for AI assistants like Claude. Listed on the MCP Registry as me.openbrowser/openbrowser-ai. No external LLM API keys required -- the MCP client provides the intelligence.

Quick Setup

Claude Code: add to your project's .mcp.json:

{
  "mcpServers": {
    "openbrowser": {
      "command": "uvx",
      "args": ["openbrowser-ai", "--mcp"]
    }
  }
}

Claude Desktop: add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "openbrowser": {
      "command": "uvx",
      "args": ["openbrowser-ai", "--mcp"],
      "env": {
        "OPENBROWSER_HEADLESS": "true"
      }
    }
  }
}

Run directly:

uvx openbrowser-ai --mcp

Tool

The MCP server exposes a single execute_code tool that runs Python code in a persistent namespace with browser automation functions. The LLM writes Python code to navigate, interact, and extract data, returning only what was explicitly requested.

Available functions (all async, use await):

Category	Functions
Navigation	navigate(url, new_tab), go_back(), wait(seconds)
Interaction	click(index), input_text(index, text, clear), scroll(down, pages, index), send_keys(keys), upload_file(index, path)
Dropdowns	select_dropdown(index, text), dropdown_options(index)
Tabs	switch(tab_id), close(tab_id)
JavaScript	evaluate(code): run JS in page context, returns Python objects
Downloads	download_file(url, filename): download a file using browser cookies, list_downloads(): list downloaded files
State	browser.get_browser_state_summary(): get page metadata and interactive elements
CSS	get_selector_from_index(index): get CSS selector for an element
Completion	done(text, success): signal task completion

Pre-imported libraries: json, csv, re, datetime, asyncio, Path, requests, numpy, pandas, matplotlib, BeautifulSoup

Configuration

Environment Variable	Description	Default
OPENBROWSER_HEADLESS	Run browser without GUI	false
OPENBROWSER_ALLOWED_DOMAINS	Comma-separated domain whitelist	(none)
OPENBROWSER_COMPACT_DESCRIPTION	Minimal tool description (~500 tokens)	false
OPENBROWSER_MAX_OUTPUT	Max output characters per execution	10000

Benchmark: Token Efficiency

CLI Benchmark: 4-Way Comparison (6 Tasks, N=3 runs)

Four CLI tools compared with a single Bash tool each. Claude Sonnet 4.6 on Bedrock. Randomized order. All achieve 100% accuracy.

CLI Tool	Duration (mean +/- std)	Tool Calls	Bedrock API Tokens	Response Chars
openbrowser-ai	84.8 +/- 10.9s	15.3 +/- 2.3	36,010 +/- 6,063	9,452 +/- 472
browser-use	106.0 +/- 9.5s	20.7 +/- 6.4	77,123 +/- 33,354	36,241 +/- 12,940
agent-browser	99.0 +/- 6.8s	25.0 +/- 4.0	90,107 +/- 3,698	56,009 +/- 39,733
playwright-cli	118.3 +/- 21.4s	25.7 +/- 8.1	94,130 +/- 35,982	84,065 +/- 49,713

openbrowser-ai uses 2.1-2.6x fewer tokens than all competitors via Python code batching and compact DOM representation.

Per-Task Token Usage

Task	openbrowser-ai	browser-use	playwright-cli	agent-browser
fact_lookup	2,504	4,710	16,857	9,676
form_fill	7,887	15,811	31,757	19,226
multi_page_extract	2,354	2,405	8,886	8,117
search_navigate	16,539	47,936	27,779	44,367
deep_navigation	2,178	3,747	4,705	5,534
content_analysis	4,548	2,515	4,147	3,189

openbrowser-ai wins 5 of 6 tasks. The advantage is largest on complex pages (search_navigate: 2.9x fewer tokens than browser-use) where code batching avoids repeated page state dumps.

Cost per Benchmark Run (6 Tasks)

Model	openbrowser-ai	browser-use	playwright-cli	agent-browser
Claude Sonnet 4.6 ($3/$15 per M)	$0.12	$0.24	$0.29	$0.27
Claude Opus 4.6 ($5/$25 per M)	$0.24	$0.45	$0.56	$0.51

Raw results are in benchmarks/e2e_4way_cli_results.json. Full 4-way comparison with methodology.

E2E LLM Benchmark: MCP Server Comparison (6 Tasks, N=5 runs)

MCP Server	Pass Rate	Duration (mean +/- std)	Tool Calls	Bedrock API Tokens
Playwright MCP (Microsoft)	100%	62.7 +/- 4.8s	9.4 +/- 0.9	158,787
Chrome DevTools MCP (Google)	100%	103.4 +/- 2.7s	19.4 +/- 0.5	299,486
OpenBrowser MCP	100%	77.0 +/- 6.7s	13.8 +/- 2.0	50,195

OpenBrowser uses 3.2x fewer tokens than Playwright and 6.0x fewer than Chrome DevTools. MCP response sizes: Playwright 1,132,173 chars, Chrome DevTools 1,147,244 chars, OpenBrowser 7,853 chars -- a 144x difference.

Full MCP comparison with methodology

CLI Usage

# Run a browser automation task with an LLM agent
uvx openbrowser-ai -p "Search for Python tutorials on Google"

# Execute code directly via persistent daemon
uvx openbrowser-ai -c "await navigate('https://example.com')"
uvx openbrowser-ai -c "print(await evaluate('document.title'))"

# Daemon management
uvx openbrowser-ai daemon start     # Start daemon (auto-starts on first -c call)
uvx openbrowser-ai daemon stop      # Stop daemon and browser
uvx openbrowser-ai daemon status    # Show daemon info
uvx openbrowser-ai daemon restart   # Restart daemon

# Install browser
uvx openbrowser-ai install

# Run MCP server
uvx openbrowser-ai --mcp

The -c flag connects to a persistent browser daemon over a Unix socket (localhost TCP on Windows). Variables persist across calls while the daemon is running. The daemon starts automatically on first use and shuts down after 10 minutes of inactivity.

Backend and Frontend Deployment

The project includes a FastAPI backend and a Next.js frontend, both containerized with Docker.

Prerequisites

• Docker and Docker Compose
• A .env file in the project root with POSTGRES_PASSWORD and any LLM API keys (see backend/env.example)

Local Development (Docker Compose)

# Start backend + PostgreSQL (frontend runs locally)
docker-compose -f docker-compose.dev.yml up --build

# In a separate terminal, start the frontend
cd frontend && npm install && npm run dev

Service	URL	Description
Backend	http://localhost:8000	FastAPI + WebSocket + VNC
Frontend	http://localhost:3000	Next.js dev server
PostgreSQL	localhost:5432	Chat persistence
VNC	ws://localhost:6080	Live browser view

The dev compose mounts backend/app/ and src/ as volumes for hot-reload. API keys are loaded from backend/.env via env_file. The POSTGRES_PASSWORD is read from the root .env file.

Full Stack (Docker Compose)

# Start all services (backend + frontend + PostgreSQL)
docker-compose up --build

This builds and runs both the backend and frontend containers together with PostgreSQL.

Backend

The backend is a FastAPI application in backend/ with a Dockerfile at backend/Dockerfile. It includes:

• REST API on port 8000
• WebSocket endpoint at /ws for real-time agent communication
• VNC support (Xvfb + x11vnc + websockify) for live browser viewing on ports 6080-6090
• Kiosk security: Openbox window manager, Chromium enterprise policies, X11 key grabber daemon
• Health check at /health

# Build the backend image
docker build -f backend/Dockerfile -t openbrowser-backend .

# Run standalone
docker run -p 8000:8000 -p 6080:6080 \
  --env-file backend/.env \
  -e VNC_ENABLED=true \
  -e AUTH_ENABLED=false \
  --shm-size=2g \
  openbrowser-backend

Frontend

The frontend is a Next.js application in frontend/ with a Dockerfile at frontend/Dockerfile.

# Build the frontend image
cd frontend && docker build -t openbrowser-frontend .

# Run standalone
docker run -p 3000:3000 \
  -e NEXT_PUBLIC_API_URL=http://localhost:8000 \
  -e NEXT_PUBLIC_WS_URL=ws://localhost:8000/ws \
  openbrowser-frontend
