I am trying use web sdk in my web app and trying this [GitHub - DeepARSDK/shoetryon-web-js: Shoe try-on example app with DeepAR Web SDK](https://github.com/DeepARSDK/shoetryon-web-js) shoe try on demo. It works fine on localhost but since I need to run it on my phone, i tried exposing my localhost using vite and it says “invalid Deepar key”, so I tried deploying my app on vercel and use vercel domain to create a key but even that is not working. So what is ideal way to setup development env. which can be used on mobile phone for testing? ---

We have a tutorial for testing with ngrok > **[Testing on a public domain | DeepAR](https://docs.deepar.ai/deepar-sdk/platforms/web/tutorials/testing-with-ngrok/)** > > In this article, we'll guide you through running DeepAR Web SDK using Ngrok. We also no longer officially support user made shoe try on, check out our new try on plugin that drastically streamlines the process > **[Online shoe shopping that feels like the real thing - ShopAR](https://www.shopar.ai/shoes)** > > AR Try-on, 3D Preview, Any Product, Any Website or Mobile App
