A browser in the cloud that sleeps for $0 and wakes in 500ms

orb-browser

A browser in the cloud that sleeps for $0 and wakes in 500ms.

Deploy Chrome on Orb Cloud. Browse, log in, interact. When you're done, put it to sleep — the entire browser is checkpointed to NVMe. Wake it later in ~500ms with everything intact: cookies, login sessions, page state. You're still logged in.

Install

pip install orb-browser

Get an API Key

curl -X POST https://api.orbcloud.dev/api/v1/auth/register \
  -H 'Content-Type: application/json' -d '{"email":"[e-mail]"}'

curl -X POST https://api.orbcloud.dev/v1/keys \
  -H "Authorization: Bearer YOUR_KEY" \
  -H 'Content-Type: application/json' -d '{"name":"my-key"}'

Quick Start

from orb_browser import OrbBrowser

orb = OrbBrowser(api_key="orb_...")

# Deploy a browser (~1-2 min first time)
orb.deploy()

# Browse
orb.navigate("https://example.com")
orb.screenshot("page.jpg")
print(orb.text())

# Sleep — $0/hr while frozen
orb.sleep()

# Wake — ~500ms, everything restored
orb.wake()
print(orb.url())  # still on example.com

# Done
orb.destroy()

Vision Agent

Give the browser a task in natural language. It screenshots the page, sends it to a vision LLM, and executes actions until done.

# No LLM key needed — uses the built-in key
result = orb.task("Go to news.ycombinator.com and tell me the top story")
print(result)

# With a specific start URL
result = orb.task(
    "Describe any images on this page",
    start_url="https://home.cern/news",
    model="google/gemini-2.0-flash-001",
)

# Ask a question about a page (text-only, faster)
answer = orb.ask("https://example.com", "What does this page say?")

CLI:

orb-browser task "Go to example.com and read the page"
orb-browser ask https://example.com "What is this page about?"

Manual Login

Need to log into Twitter, Gmail, or any site with OAuth/2FA? Use the live browser view:

from orb_browser import OrbBrowser

orb = OrbBrowser(api_key="orb_...")
orb.deploy()

# Navigate to login page
orb.navigate("https://x.com/login")

# Open the live view in your browser
print(orb.live_url)
# → https://abc12345.orbcloud.dev/live

# Click, type, do 2FA in the live view...
# When done, checkpoint the session:

orb.sleep()
print(f"Saved! ID: {orb.computer_id}")

# Later — wake and you're still logged in:
orb.connect("COMPUTER_ID", AGENT_PORT)
orb.wake()

API

orb = OrbBrowser(api_key="orb_...")

Lifecycle

Method	Description
orb.deploy()	Deploy browser VM (~1-2 min)
orb.sleep()	Checkpoint to NVMe ($0)
orb.wake()	Restore (~500ms)
orb.destroy()	Delete the VM
orb.connect(id, port)	Connect to existing VM

Browse

Method	Description
orb.navigate(url)	Go to URL
orb.back()	Go back
orb.forward()	Go forward
orb.click(selector)	Click element
orb.click(x=100, y=200)	Click coordinates
orb.fill(selector, value)	Fill input field
orb.type(text)	Type text
orb.press(key)	Press key (Enter, Tab, etc)
orb.scroll(direction, amount)	Scroll up/down
orb.evaluate(js)	Run JavaScript

Agent

Method	Description
orb.task(prompt)	Vision agent: screenshot + LLM + actions
orb.ask(url, question)	Navigate + read text + LLM answer

Read

Method	Description
orb.screenshot(path)	JPEG screenshot
orb.url()	Current URL + title
orb.text()	Page text content
orb.html()	Page HTML
orb.cookies()	All cookies

Properties

Property	Description
orb.vm_url	VM HTTPS URL
orb.live_url	Live browser view URL
orb.computer_id	VM ID (save for reconnecting)
orb.state	init, deploying, running, sleeping, destroyed

Live View

Open orb.live_url in your browser to see and control the remote Chrome:

• Click anywhere on the screen to click
• Type on your keyboard to type in the browser
• URL bar to navigate
• Back/Forward buttons

This is how you log into sites that need OAuth, 2FA, or CAPTCHA.

How It Works

1. deploy() creates a VM on Orb Cloud with Python + Playwright + Chrome
2. Chrome runs locally in the VM — no remote WebSocket, no CDP over internet
3. You send HTTP requests, the agent executes them against local Chrome
4. sleep() uses CRIU to checkpoint the entire process tree to NVMe
5. wake() restores everything in ~500ms — Chrome doesn't know it was frozen

Cost

State	Cost
Running	~$0.03/hr
Sleeping	$0/hr
1,000 browsers, 90% sleeping	~$50/month
