Quickly create a new GitHub repository that takes automated screenshots of a web page using shot-scraper.

Read more about how this works in Instantly create a GitHub repository to take screenshots of a web page.

simonw/simonwillison-net-shot is an example repository created using this template.

Visit https://github.com/simonw/shot-scraper-template/generate

Pick a name for your new repository, and paste the URL of the page you would like to take screenshots of into the description field (including the http:// or https://).

Then click Create repository from template.

Your new repository will be created, and a script will run which will do the following:

• Add a shots.yml file to your repository containing the URL of the page you requested
• Take a screenshot of that URL and add that to you repository as a file called shot.png

You can then edit that shots.yml file to customize your screenshot, or add more URLs - see below.

If the script does not run when the repository is first created you may need to Enable Actions first:

• Click the "Actions" tab
• Clice "Enable Actions"
• Run the "Take screenshots" workflow as described below

To re-take the screenshot:

• Click "Actions"
• Select the "Take screenshots" workflow
• Click the "Run workflow" menu item
• Click the green "Run workflow" button

The repository will keep a history of every previous version of each screenshot, which is useful for keeping track of visual changes to a page.

The initial shots.yml file in your repository should look like this:

- url: https://simonwillison.net/
  output: shot.png
  height: 800

To change the name of the file that the screenshot is saved to, change output: shot.png to a different file name.

To take a full height image of the page, remove the height: 800 line.

To add additional screenshots, add them to the YAML file like this:

- url: https://simonwillison.net/
  output: shot.png
  height: 800
- url: https://www.example.com/
  output: example.png
  height: 800

Other useful options include:

• wait: 3000 to add a 3 second delay before taking the shot (in case some things need more time to load)
• javascript: ... to execute custom JavaScript before taking the shot - to activate menus or hide elements or similar
• quality: 80 to save a smaller, lower quality JPEG image

This example takes a shot of the LA Times homepage after hiding ads and the terms of service prompt:

- url: https://www.latimes.com/
  output: latimes.jpg
  width: 1600
  height: 1600
  quality: 80
  wait: 2000
  javascript: |
    document.querySelectorAll(
      '[data-ad-rendered],#ensNotifyBanner'
    ).forEach(el => el.style.display = 'none')

Further options are described in the shot-scraper README file.
