Using one DeepAR SDK project app on multiple domains is supported for projects using the <100k MAU (Pro) subscription and above as an add-on premium feature.
Please contact our team if you would like to request this feature.
By default, DeepAR SDK projects are limited to one domain per app.
Note: You can use multiple links using DeepAR under one domain such as domain_name.com/app1 domain_name.com/app2.
