Please check out what Puppeteer can do for your own use case and host on your own servers.

The API can perform 3 actions:

URL - the URL with encoded pathname, search and hash.

Global parameters:

• width - width of viewport/screenshot (default: 1024)

For version 1.0, this uses cheeaun/puppeteer Docker image.

For version 2.0, this uses some parts from Zeit's now-examples: misc-screenshot.
