I have a Rails app that I want to capture a screenshot of a webpage when the user enters a url.
Is it possible to do this in Rails (is there any gem that would do this?)
If not, are there any reliable services that generate live screenshots

I use IMGKit gem for that: https://github.com/csquared/IMGKit

It is worth mentioning that this only works for HTML with inlined CSS, and no javascript is executed. You can use a gem like `premailer` to inline your CSS, but the results aren't great. – Navid Khan May 27 '20 at 14:55

ScreenCap gem which uses PhantomJS under the hood. Grab whole pages or just specific divs, or even exact x y coordinates.

Is there a way to allow the user to capture a screen-shot of their page with this gem after they have logged in? – Ctpelnar1988 Mar 26 '17 at 06:29

@Ctpelnar1988 Yes, the gem has the ability to fill out login form fields like username and password, e.g. `fill_in 'Username or Email', :with => '[email protected]'` – Joshua Pinter Aug 11 '18 at 06:18
