Hyperbrowser Python SDK

Checkout the full documentation here

Installation

Currently Hyperbrowser supports creating a browser session in two ways:

• Async Client
• Sync Client

It can be installed from pypi by running :

pip install hyperbrowser

The browser-control examples below also use Playwright:

pip install playwright

Configuration

Both the sync and async client follow similar configuration params

API Key

The API key can be configured either from the constructor arguments or environment variables using HYPERBROWSER_API_KEY

If no API key is provided, the client falls back to a saved OAuth session created by hx auth login. By default it reads ~/.hx_config/auth/default.json, or ~/.hx_config/auth/<profile>.json when HYPERBROWSER_PROFILE or ClientConfig(profile=...) is set.

Profile names must match ^[A-Za-z0-9._-]+$.

base_url and HYPERBROWSER_BASE_URL accept either https://host or https://host/api. The client normalizes both to the same control-plane base URL.

Usage

Hyperbrowser 1.0 accepts plain dictionaries for request parameters. Method signatures use TypedDict definitions, so editors can autocomplete keys at every nested level:

from hyperbrowser import Hyperbrowser

client = Hyperbrowser(api_key="test-key")

# Preferred in 1.0: autocomplete works directly in the dictionary.
session = client.sessions.create(
    {
        "use_stealth": True,
        "screen": {"width": 1920, "height": 1080},
    }
)

Existing Pydantic request classes remain accepted, so upgrading does not require an immediate rewrite:

from hyperbrowser.models import CreateSessionParams, ScreenConfig

session = client.sessions.create(
    CreateSessionParams(
        use_stealth=True,
        screen=ScreenConfig(width=1920, height=1080),
    )
)

Import request annotations from hyperbrowser.types when a named variable is useful. The same names under hyperbrowser.models refer to the legacy Pydantic request classes. Responses remain Pydantic models.

JSON Schema fields accept raw schema values, including object schemas with $defs, $ref, or custom keywords, and boolean schemas where the API supports them. Those schemas and other user-owned mappings are preserved as data; only SDK-owned request keys are translated to their API aliases. Schema fields documented as accepting a model class can also generate a schema from a Pydantic model.

See the Hyperbrowser Python SDK 1.0 migration guide for the complete compatibility details and migration checklist.

Async

import asyncio
from hyperbrowser import AsyncHyperbrowser
from playwright.async_api import async_playwright

HYPERBROWSER_API_KEY = "test-key"

async def main():
    async with AsyncHyperbrowser(api_key=HYPERBROWSER_API_KEY) as client:
        session = await client.sessions.create()

        try:
            async with async_playwright() as playwright:
                browser = await playwright.chromium.connect_over_cdp(
                    session.ws_endpoint
                )
                context = browser.contexts[0]
                page = context.pages[0]

                print("Navigating to Hacker News...")
                await page.goto("https://news.ycombinator.com/")
                print("Page title:", await page.title())
        finally:
            await client.sessions.stop(session.id)

# Run the asyncio event loop
asyncio.run(main())

Sync

from playwright.sync_api import sync_playwright
from hyperbrowser import Hyperbrowser

HYPERBROWSER_API_KEY = "test-key"

def main():
    client = Hyperbrowser(api_key=HYPERBROWSER_API_KEY)
    session = client.sessions.create()

    ws_endpoint = session.ws_endpoint

    # Launch Playwright and connect to the remote browser
    with sync_playwright() as p:
        browser = p.chromium.connect_over_cdp(ws_endpoint)
        context = browser.new_context()
        
        # Get the first page or create a new one
        if len(context.pages) == 0:
            page = context.new_page()
        else:
            page = context.pages[0]
        
        # Navigate to a website
        print("Navigating to Hacker News...")
        page.goto("https://news.ycombinator.com/")
        page_title = page.title()
        print("Page title:", page_title)
        
        page.close()
        browser.close()
        print("Session completed!")
    client.sessions.stop(session.id)

# Run the asyncio event loop
main()

Sandboxes

The sync and async clients expose the same sandbox APIs through client.sandboxes.

Create a sandbox with pre-exposed ports

from hyperbrowser import Hyperbrowser

client = Hyperbrowser(api_key="test-key")
sandbox = client.sandboxes.create(
    {
        "image_name": "node",
        "cpu": 2,
        "memory_mib": 2048,
        "disk_mib": 8192,
        "exposed_ports": [{"port": 3000, "auth": True}],
    }
)

print(sandbox.exposed_ports[0].browser_url)
print(sandbox.cpu, sandbox.memory_mib, sandbox.disk_mib)
sandbox.stop()
client.close()

cpu, memory_mib, and disk_mib are only supported for image launches.

Manage volumes and mount them in a sandbox

from hyperbrowser import Hyperbrowser

client = Hyperbrowser(api_key="test-key")

volume = client.volumes.create({"name": "project-cache"})
all_volumes = client.volumes.list()
same_volume = client.volumes.get(volume.id)

sandbox = client.sandboxes.create(
    {
        "image_name": "node",
        "mounts": {
            "/workspace/cache": {
                "id": same_volume.id,
                "type": "rw",
                "shared": True,
            }
        },
    }
)

sandbox.stop()
client.close()

List sandboxes with filters

from hyperbrowser import Hyperbrowser

client = Hyperbrowser(api_key="test-key")
result = client.sandboxes.list(
    {
        "status": "active",
        "search": "sandbox",
        "start": 1711929600000,
        "end": 1712016000000,
        "limit": 20,
    }
)

for sandbox in result.sandboxes:
    print(sandbox.id, sandbox.status)

List snapshots for a specific image

from hyperbrowser import Hyperbrowser

client = Hyperbrowser(api_key="test-key")
snapshots = client.sandboxes.list_snapshots(
    {"image_name": "node", "status": "created", "limit": 10}
)

Expose and unexpose ports

from hyperbrowser import Hyperbrowser

client = Hyperbrowser(api_key="test-key")
sandbox = client.sandboxes.create(
    {"image_name": "node", "cpu": 2, "memory_mib": 2048, "disk_mib": 8192}
)

result = sandbox.expose({"port": 8080, "auth": True})
print(result.url, result.browser_url)

sandbox.unexpose(8080)

Batch file writes with per-file options

from hyperbrowser import Hyperbrowser

client = Hyperbrowser(api_key="test-key")
sandbox = client.sandboxes.create({"image_name": "node"})

sandbox.files.write(
    [
        {
            "path": "/tmp/config.json",
            "data": '{"debug":true}\n',
            "append": True,
            "mode": "600",
        },
        {"path": "/tmp/blob.bin", "data": b"\x00\x01\x02"},
    ]
)

Resume terminal output after reconnect

from hyperbrowser import Hyperbrowser

client = Hyperbrowser(api_key="test-key")
sandbox = client.sandboxes.create({"image_name": "node"})
terminal = sandbox.terminal.create({"command": "bash"})

connection = terminal.attach(cursor=10)
for event in connection.events():
    print(event)
