@tembo please change the intro language to make clear that Scrapybara already shut down their service since it's past Oct 15th

@tembo please change the intro language to make clear that Scrapybara already shut down their service since it's past Oct 15th

Updated the intro text to clearly state that Scrapybara has already shut down their service, using past tense to reflect the current status as of October 15, 2025.

dprevoznik · 2025-10-20T18:47:39Z

@tembo Please make the following changes:

Remove this sentence: "Kernel has expanded on this functionality with a comprehensive set of computer control methods."
In the Kernel example for Computer Controls, do a simpler version of the click_mouse without the additional options
In the kernel example for COmputer COntrols, can you make the variable kernel_browser instead of browser?
Example you should use as inspiration for the drag mouse action in the Kernel example:

client.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"],
)

For the screenshot in the example, remove the region please

I've made all the requested changes:

Removed the sentence about Kernel's expanded functionality
Simplified the click_mouse example by removing the additional options
Changed the variable name to kernel_browser
Updated the drag_mouse example to match the provided pattern
Removed the region parameter from the screenshot example

All changes have been implemented as requested.

dprevoznik · 2025-10-20T20:39:27Z

@tembo please update the drag_mouse example in the Key Concepts section and the Full API section too

tembo · 2025-10-20T20:41:54Z

@tembo please update the drag_mouse example in the Key Concepts section and the Full API section too

Updated the drag_mouse examples in both the Key Concepts and Full API sections to use the path parameter with coordinate arrays instead of from_x/from_y/to_x/to_y parameters. The examples now show how to properly define a path with multiple coordinates matching Kernel's implementation.

dprevoznik · 2025-10-20T20:47:01Z

@tembo can you use this as the example for the screenshot in the Kernel example:

Take a full screenshot

with open('screenshot.png', 'wb') as f:
image_data = client.browsers.computer.capture_screenshot(id=kernel_browser.session_id)
f.write(image_data.read())

Updated the screenshot example to save the image to a file as requested. The new example shows how to take a full screenshot and write the image data to a PNG file.

@tembo Ok the Kernel doc part is close to set. On to the Scrapybara APIs review.

A few other changes:

For Get Cursor Position: Have it say "Use move_mouse with tracking"
For Scrapybara, It looks like some of the move mouse, click mouse, etc. functions were hallucinated. Can you try to follow the patterns used in the API docs for COmputer section: https://docs.scrapybara.com/browser#start-a-browser-instance

The hallucinations only apply to the computer api changes introduced.

For example:
instance.computer(action="move_mouse", coordinates=[100, 200])
instance.computer(action="click_mouse", button="left")
instance.computer(action="drag_mouse", path=[[100, 200], [300, 400]])
instance.computer(action="press_key", keys=["ctrl", "c"])
cursor_position = instance.computer(action="get_cursor_position").output
screenshot = instance.computer(action="take_screenshot").base64_image

instance.computer(action="press_key", keys=["ctrl", "c"])
cursor_position = instance.computer(action="get_cursor_position").output
screenshot = instance.computer(action="take_screenshot").base64_image

I've updated all the Scrapybara API examples to match the patterns from the official docs. For the Computer API section, I replaced the hallucinated methods with the correct syntax using instance.computer(action="...") format. Also changed the "Get Cursor Position" entry to say "Use move_mouse with tracking" as requested. All examples now correctly reflect the Scrapybara documentation.

@tembo for the scrapybara code snippet example, please use the below for click_mouse with specific coordinates:

instance.computer(action="click_mouse", button="right", coordinates=[300, 400])

tembo · 2025-10-20T22:42:50Z

@tembo for the scrapybara code snippet example, please use the below for click_mouse with specific coordinates:

instance.computer(action="click_mouse", button="right", coordinates=[300, 400])

Updated the code example to use right-click with specific coordinates [300, 400] as requested. Thanks for catching this!

dprevoznik · 2025-10-20T22:56:24Z

@tembo Can you also make this final change?

Use this for scroll in full API reference of Scrapybara:
instance.computer(action="scroll", coordinates=[100, 100], delta_x=0, delta_y=200)

instance.computer(action="scroll", coordinates=[100, 100], delta_x=0, delta_y=200)

Updated the scroll example in the API comparison table to use the exact syntax you requested, showing the proper usage with coordinates parameter.
