Part of the Twitter Fabric toolkit, Screengrab from fastlane is entirely automated from the command line. Built to save time, Screengrab takes the work of grabbing, lining up and localizing your shots out of your hands.
Speaking of localization, Screengrab even lets you verify that labels fit on screens of all sizes. If you’re working on a team, Screengrab only needs to be configured once for everyone to use.
It’s also not contained; Screengrab works with the rest of the fastlane toolset. That means you can grab screenshots and deploy using Supply for a more streamlined updating process.
Of course, Screengrab is also open source and available on GitHub.
