If you were using Scrapybara for browser automation, Kernel is here to help you migrate seamlessly. ## Key Concepts | Feature | Scrapybara | Kernel | | ----------------- | ----------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------- | | **Start Browser** | `client.start_browser()` | `kernel.browsers.create()` | | **Standby Mode** | `instance.pause()` / `instance.resume()` | Automatic standby mode | | **CDP URL** | `instance.get_cdp_url().cdp_url` | Returns `cdp_ws_url` in create response | | **Live View** | `instance.get_stream_url().stream_url` | Returns `browser_live_view_url` in create response | | **Stealth Mode** | ❌ Not available | Create browser with `stealth: true` | | **Replays** | ❌ Not available | `kernel.browsers.replays.start()` and `kernel.browsers.replays.stop()` | | **Save Auth** | `instance.browser.save_auth(name="default")` | Create [Profile](/auth/profiles). Then create browser with `kernel.browsers.create(profile={"name": "profile1", "save_changes": true})` | | **Click** | `instance.computer(action="click_mouse", button="left")` | `kernel.browsers.computer.click_mouse(id=session_id, x=100, y=200)` | | **Drag** | `instance.computer(action="drag_mouse", path=[[100, 200], [300, 400]])` | `kernel.browsers.computer.drag_mouse(id=session_id, path=[[100, 200], [150, 220], [200, 260]])` | | **Screenshot** | `instance.computer(action="take_screenshot").base64_image` | `kernel.browsers.computer.capture_screenshot(id=session_id)` | ## How to migrate ### Basic Browser Creation **Scrapybara** ```python theme={null} from scrapybara import Scrapybara from playwright.async_api import async_playwright client = Scrapybara(api_key="your_api_key") instance = client.start_browser(timeout_hours=1) cdp_url = instance.get_cdp_url().cdp_url async with async_playwright() as p: browser = await p.chromium.connect_over_cdp(cdp_url) page = browser.contexts[0].pages[0] await page.goto("https://example.com") await browser.close() instance.stop() ``` **Kernel** ```python theme={null} from kernel import Kernel from playwright.async_api import async_playwright kernel = Kernel() kernel_browser = kernel.browsers.create(timeout_seconds=3600) cdp_url = kernel_browser.cdp_ws_url async with async_playwright() as p: browser = await p.chromium.connect_over_cdp(cdp_url) page = browser.contexts[0].pages[0] await page.goto("https://example.com") await browser.close() await kernel.browsers.delete_by_id(kernel_browser.session_id) ``` ### Save & Reuse Authentication **Scrapybara** ```python theme={null} # First session - save auth instance = client.start_browser() # ... login to website via Playwright ... auth_state = instance.browser.save_auth(name="my-login") instance.stop() # Second session - load auth instance2 = client.start_browser() instance2.browser.authenticate(auth_state_id=auth_state.auth_state_id) # ... browser now has saved cookies ... ``` **Kernel** ```python theme={null} # First session - save auth profile = await kernel.profiles.create(name="my-login") kernel_browser = await kernel.browsers.create( profile={"name": "my-login", "save_changes": True} ) # ... login to website via Playwright ... await kernel.browsers.delete_by_id(kernel_browser.session_id) # Second session - load auth kernel_browser2 = await kernel.browsers.create( profile={"name": "my-login"} ) # ... browser now has saved cookies ... ``` ### File Download **Scrapybara** ```python theme={null} instance = client.start_browser() # ... trigger download in browser ... # Then use file operations downloaded_file = instance.file(command="read", path="/download/path") ``` **Kernel** ```python theme={null} kernel_browser = await kernel.browsers.create() # ... trigger download in browser via Playwright ... # Then read from filesystem file_response = await kernel.browsers.fs.read_file( kernel_browser.session_id, path="/tmp/downloads/file.pdf" ) await file_response.write_to_file("local-file.pdf") ``` ### Long-Running Sessions **Scrapybara** ```python theme={null} # Pause/resume for long-running sessions instance = client.start_browser(timeout_hours=24) # ... do some work ... instance.pause() # Pause to save costs # ... later ... instance.resume() # Resume work ``` **Kernel** ```python theme={null} # Automatic standby mode + extended timeout kernel_browser = await kernel.browsers.create( timeout_seconds=86400 ) # ... do some work ... # Browser enters standby mode between connections # Later - reuse the exact browser instance with full state kernel_browser2 = await kernel.browsers.create( timeout_seconds=86400 ) ``` ### Computer Controls Both Scrapybara and Kernel provide Computer Controls APIs that allow you to programmatically control the browser environment at the system level - including mouse movements, clicks, keyboard input, and screenshots. **Scrapybara** ```python theme={null} instance = client.start_browser() # Click at specific coordinates instance.computer(action="click_mouse", button="right", coordinates=[300, 400]) # Drag from one position to another instance.computer(action="drag_mouse", path=[[100, 200], [300, 400]]) # Type text instance.computer(action="type_text", text="Hello World") # Take a screenshot screenshot = instance.computer(action="take_screenshot").base64_image ``` **Kernel** ```python theme={null} kernel_browser = await kernel.browsers.create() # Click at specific coordinates kernel.browsers.computer.click_mouse( id=kernel_browser.session_id, x=100, y=200 ) # Drag from one position to another kernel.browsers.computer.drag_mouse( id=kernel_browser.session_id, path=[[100, 200], [150, 220], [200, 260]], button="left", delay=0, steps_per_segment=10, step_delay_ms=50, hold_keys=["Shift"] ) # Type text with optional delay kernel.browsers.computer.type_text( id=kernel_browser.session_id, text="Hello World", delay=100 ) # Take a full screenshot with open('screenshot.png', 'wb') as f: image_data = kernel.browsers.computer.capture_screenshot(id=kernel_browser.session_id) f.write(image_data.read()) ``` For a complete reference of all available Computer Controls methods in Kernel, see the [Computer Controls documentation](/browsers/computer-controls). ## Full API Comparison | Feature | Scrapybara | Kernel | | ----------------------- | ------------------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------- | | **Create Browser** | `client.start_browser()` | `kernel.browsers.create()` | | **Get CDP URL** | `instance.get_cdp_url().cdp_url` | Returns `cdp_ws_url` in create response | | **Get Live View** | `instance.get_stream_url().stream_url` | Returns `browser_live_view_url` in create response | | **Delete Browser** | `instance.stop()` | `kernel.browsers.delete_by_id(session_id)` | | **List Browsers** | `kernel.get_instances()` | `kernel.browsers.list()` | | **Save Auth State** | `instance.browser.save_auth(name="default")` | Create [Profile](/auth/profiles).
