 If you don't want to pay $29/month for Screen Studio but want a much simpler version that does what most people seem to need, making beautiful product demos and walkthroughs, here's a free-to-use app for you. OpenScreen does not offer all Screen Studio features, but covers the basics well!
 
 Screen Studio is an awesome product and this is definitely not a 1:1 clone. OpenScreen is a much simpler take, just the basics for folks who want control and don't want to pay. If you need all the fancy features, your best bet is to support Screen Studio (they really do a great job, haha). But if you just want something free (no gotchas) and open, this project does the job!
