A runtime service to use live website screenshots on your site.

Read the Blog post: Building an Automated Screenshot Service on Netlify in ~140 Lines of Code.

Image URLs have the formats:

/:url/
/:url/:size/
/:url/:size/:aspectratio/
/:url/:size/:aspectratio/:zoom/

• url must be URI encoded.
• Valid size values:
  • small: 375×___ (default)
  • medium: 650×___
  • large: 1024×___
    • aspectratio of 9:16 is not supported (throws an error)
  • opengraph: always 1200×630, works with zoom
    • aspectratio is ignored (no errors thrown)
• Valid aspectratio values:
  • 1:1 (default)
  • 9:16
• Valid zoom values:
  • bigger (1.4 devicePixelRatio)
  • smaller (0.71 devicePixelRatio)

If the screenshots aren’t updating at a high enough frequency you can pass in your own cache busting key using an underscore prefix _ after your URL.

This can be any arbitrary string tied to your unique build, here’s an example that uses today’s date:

/:url/_20210802/
/:url/:size/_20210802/
/:url/:size/:aspectratio/_20210802/
/:url/:size/:aspectratio/:zoom/_20210802/
