Get screenshots of the websites in different resolutions

Build Status

A good way to make sure your websites are responsive.

It's speedy and generates 100 screenshots from 10 different websites in just over a minute.

CLI app


npm install --global pageres

PhantomJS, which is used for generating the screenshots, is installed automagically, but in some rare cases it might fail to and you'll get an Error: spawn EACCES error. Download PhantomJS manually and reinstall pageres if that happens.


$ pageres --help

Get screenshots of websites in different resolutions.

Specify urls and screen resolutions as arguments. Order doesn't matter.

  pageres <url> <resolution> [<resolution> <url> ...]
  pageres [<url> <resolution> ...] < <file>
  cat <file> | pageres [<url> <resolution> ...]

  pageres 1366x768 1600x900
  pageres 1366x768 < urls.txt
  cat screen-resolutions.txt | pageres

You can also pipe in a newline separated list of urls and screen resolutions which will get merged with the arguments.
If no screen resolutions are specified it will fall back to the ten most popular ones according to w3counter.

Programmatic API


npm install --save pageres


var pageres = require('pageres');

pageres([''], ['1366x768', '1600x900'], function () {
