A command-line browser automation tool that controls a web browser. It can open pages, inspect elements, click, type, take screenshots, and extract page information.

Use it for web testing, filling forms, navigating multi-step pages, taking screenshots, and extracting data.

It removes the need to perform repetitive browser actions manually when testing or collecting information from websites.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00047	$0.03273
Opus 5	$0.00023	$0.01636
Sonnet 5	$0.00009	$0.00655
Haiku 4.5	$0.00005	$0.00327

Security

Grade A, and why

browser-use scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to browser-use — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Browser Automation with browser-use CLI

The browser-use command provides fast, persistent browser automation. It maintains browser sessions across commands, enabling complex multi-step workflows.

Installation

# Run without installing (recommended for one-off use)
uvx "browser-use[cli]" open https://example.com

# Or install permanently
uv pip install "browser-use[cli]"

# Install browser dependencies (Chromium)
browser-use install

Quick Start

browser-use open https://example.com           # Navigate to URL
browser-use state                              # Get page elements with indices
browser-use click 5                            # Click element by index
browser-use type "Hello World"                 # Type text
browser-use screenshot                         # Take screenshot
browser-use close                              # Close browser

Core Workflow

Navigate: browser-use open <url> - Opens URL (starts browser if needed)
Inspect: browser-use state - Returns clickable elements with indices
Interact: Use indices from state to interact (browser-use click 5, browser-use input 3 "text")
Verify: browser-use state or browser-use screenshot to confirm actions
Repeat: Browser stays open between commands

Browser Modes

browser-use --browser chromium open <url>      # Default: headless Chromium
browser-use --browser chromium --headed open <url>  # Visible Chromium window
browser-use --browser real open <url>          # User's Chrome with login sessions
browser-use --browser remote open <url>        # Cloud browser (requires API key)

chromium: Fast, isolated, headless by default
real: Uses your Chrome with cookies, extensions, logged-in sessions
remote: Cloud-hosted browser with proxy support (requires BROWSER_USE_API_KEY)

Commands

Navigation

browser-use open <url>                    # Navigate to URL
browser-use back                          # Go back in history
browser-use scroll down                   # Scroll down
browser-use scroll up                     # Scroll up

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
