When I’m working on localhost it works but after deploy it i got this alert “DeepAR license not valid”
I have put my license key but my question is it sholud be premium or not?
You can deploy a DeepAR project using a free license key! After your project reaches 10 users in a given month, the DeepAR watermark will show up but the AR features should continue to work.
One thing that can cause this issue is a project URL that isn’t the same as the domain that you’ve deployed the project to. You need to enter the domain name , not the URL where your app is running.
For example, if your app is running on https://www.domain.com/try-on/glasses the domain you need to enter is www.domain.com . Be sure to leave out any protocol name (like https ) and additional paths (like try-on/glasses ). You can check out more on our docs.
If that doesn’t fix it, please feel free to send us the project domain link (via email if you prefer - zak@deepar.ai) and we’ll take a look 
I’m a bit unsure about how to verify if the URL matches the domain name. However, I have already sent my deployed web app to your email. Thank you for your assistance.
