How much does Yodeck cost?

First installation Free then $79 for each player

This is literally on the main page here. It is free for one device that you have to provide. For us this was great to trial it and I had a personal raspberry pie that we could test with. If you move to the paid plan ($7.99 /month paid annually) you can get a free device (or for a minor extra cost you can get an upgrade device to keep if you are doing more process/memory intense content). Each screen you want to display is the extra cost with the same features as the free version. It looks like there might be an enterprise level but the standard level did everything we wanted and needed.

Yodeck is completely free if you only use it on one screen. That's right, there are no strings attached. It's a great way for smaller businesses to try out stuff in the realm of digital signage without spending a dollar. The beauty of Yodeck, however, is how it evolves with you. When your requirements grow and you begin adding more screens, they will introduce subscription plans. As of this writing, plans range from $7 to $12. These layouts are quite adaptable, and customized to a variety of requirements, whether you're adding a couple of additional screens or constructing an entire network. What is the price? It grows in size as you use more screens. So it's either they cost very reasonably or cost nothing at all.
