Searching for a WebAR for m’y classroom

Hello everyone ! Sorry if it’s the wrong feed :/

I’m a spanish teacher and i discovered AR this summer and i think it’s a great way to make my students interested and to show them spanish paintings, architecture… etc

I began this year with myWebAR from DEVAN but i reached the limit of the free trial.

So, I’m here because i’m looking for a Webar platform to work with in class. Do you know free platforms ? Or good and cheap ones ?

Basically i’m looking for a web platform to « place » my 2D or 3D objects, generate a QR that allow my students to access the AR file without an app. Just that !

Thank you for your help !
