Send finished html5 canvas project

"But they don't have adobe animate to open and they don't need the source code and so on. 
How can I send them the project to run on their machine?"

That isn't how web files work. 

When you publish (File > Publish) an Animate project you are creating a webpage:

• HTML document that holds the Canvas element

• JS document that the runs the code to make things display and move inside the canvas

• Folders of images, audio that the Javascript links to

So in order to run what you made they need all of that, lust like any other website project.

They don't need the source .fla but the published content they need, and they would need all of the files that are created when you publish the project.

Once they have all the published files they can use it for whatever their goal is. But in general this content is intended to be run off a web server like any other web page content.

Hi.

The best way is to host your content on a server like any other website.

The easiest web hosting service and that I use the most is Netlify. You can literally drag and drop a folder with your files onto their website and in a matter of seconds you get a link to access your content from anywhere. And it's free if you don't need advanced features.

I hope it helps.
