Capture screenshots of websites in various resolutions. 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. It can also be used to render SVG images.

See pageres for the programmatic API and issues tracker.

$ npm install --global pageres-cli

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.

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

If no resolution is specified it will default to 1366x768 which is the most popular resolution.

pageres <url> <resolution>
pageres <resolution> <url>

# <url> can also be a local file path.
pageres <file> <resolution>

List multiple urls and resolutions for pageres to capture all combinations.

pageres <url> <resolution> ...

pageres todomvc.com 1024x768 1366x768 # 2 screenshots
pageres todomvc.com yeoman.io 1024x768 # 2 screenshots
pageres todomvc.com yeoman.io 1024x768 1366x768 # 4 screenshots

Group arguments with square brackets.
