I tried using the demo files (and modifying them slightly), they work great exporting to Windows standalone exe & Android apk, but I get errors when I export to WebGL for browser use:

EasyAR is a C++ SDK, and we provide Unity plugins for some platforms, not including Javascript.

Are you planning to release any version compatible to WebGL?
commented Jul 16, 2018 by kenn (18,790 points)
Not yet for local tracking. Web(GL) support is much more than a Javascript binding.
If you need only the image detection feature, then you can use that in WebGL, because you can use web API of EasyAR CRS. We have some webGL demos for that. And we also have a few more features for that kind of usage like hand and body gesture detection. Send us an email (support@easyar.com) if you want to know more.

Is WebGL compatibility (within Unity) on VisionStar road map?

For those who come into this thread looking for Unity WebGL support, the answer is "YES and NO", if you are coming for "EasyAR" instead of "EasyAR Sense" or "EasyAR Sense Unity Plugin" or some other specific feature(s).

EasyAR has quite broad products from pure native SDKs and Unity plugins to cloud services. And there are quite a lot of different features in every product. You can always use cloud services in (Unity) Web(GL), but you have to use them like using any other cloud service you may see in the world.

We have also added some description/classification in the latest documents for the EasyAR Sense Unity Plugin: https://help.easyar.com/EasyAR%20Sense%20Unity%20Plugin/latest/GettingStarted/Platform-Requirements.html#webgl
