Is the Marzipano tool and source code completely free to use?

Hi, 

  Is the Marzipano tool and source code completely free to use? Can we use it for commercial purpose?

Hi,

Good question. I cant seem to find the exact question. Checking out the different hits I get from googling;

https://github.com/google/marzipano 

What I read, when you go to and read the file LICENSE, it says it is released under Apache 2.0 license.

Permissions: free for commercial use, modification, distribution, patent use and private use. Liability: trademark use, liability and warranty.

Quote "Google bought Marzipano and made it free for all projects, including commercial. "

https://groups.google.com/g/marzipano/c/NYdHu75EFy0

Quote by creator of Marzipano: "You're free to use and modify both Marzipano itself and tours generated by the Marzipano Tool (including for commercial purposes) under the terms of the Apache license."

The last threat is actually by the creator itself.

So bottom line: This tool is completely free, and you can use it in a commercial setting.

HiHo,
may i ask if you know how exactly the license should be added to projects?

Lets say i got these situation:
1: I created a tour with marzipano and i want to show it as a demo on my commercial website
2: I created a tour for a customer who wants to show it on their website
3: I sell creating panos and tours as a service

Q:
a: Where exactly do i need to put the license text? (In the HTML of the index? Visible under the panorama? Somewhere else?)
b. What exact text do i have to put?

(I am absolutely unexperienced with the different licensing conditions and the "How to")

Kind regards
axel

Hi Axel,

I don't think that any of the licenses involved specify exactly where you must put your license terms. The licences I know, like GPL, MIT, Apache, BSD, are all general software licenses, they apply to any kind of software and not only virtual tour plugins. This is a reason why they can't specify that the license must go on the "index.html" for example. Many software won't have this file. That said, you are going to have your software distributed. It is up to you how and where you will expose your license, but there, when you decide where you will put it (let's say, in a LICENSE.txt at the root directory of a publication) the license must be mentioned.

The marzipano code has many license terms distributed in many of its pieces of code, as it uses many sources of codes. In each piece it is possible to see its license, so as you use it I believe their license terms are already there. But those licenses have implications: GPL, for example, say that you can't close your code if you use any piece of GPL license code. MIT, BSD and Apache, on the other side, let you enclosure and not share your modifications. That said, if there is any GPL license inside marzipano you must also share your code, at least when asked for. I don't know if all GPL versions also obbly you to share using GPL, but surely some do.

I've searched for licenses here and found those:

So, as I said, the files already list each one's license. I didn't find any GPL, which is more restrictive. Based on found Apache and MIT licenses I would say that you might use it without worries, just keeping the credit of the original developers inside the code. In other words, if you change the code, don't erase their credits.
